Studying the brain can be a hard thing to accomplish. There are quite a few methods that our bio psychologist’s use to study the brain. As stated in Biopsychology 8 Ch5, “Some of the methods used to study the brain include: X-rays, contrast x-rays, magnetic resonance imaging (also known as MRI), positron emission tomography (also known as PET), and in my opinion the best way of studying the brain; functional MRI.” Unlike using just MRI to visualize the brain; functional MRI is a great way to study the activity of the brain, while being able to visualize the brain. When using just a magnetic response imaging machine to study the brain, the only great thing about using it is being able to visualize what is going on in an individual’s brain. For example; if someone were to have an appointment to look at their brain, to determine whether or not they have a tumor; this type of method would be a great method to use. The reason I say this is because an MRI machine is able to visualize if there is anything growing inside the brain. While an MRI may be a great method to use for this type of procedure; a functional MRI would be able to not only visualize what is growing in the brain; it would be able to show the doctor the activity of the tumor and other activity in the brain. As stated in Biopsychology 8 Ch5, “Functional MRI produce images representing the increase in oxygen flow in the blood to active areas in the brain.” Another great aspect of Functional MRI’s are that unlike other methods used to study the brain; they are a UN invasive way to study the brain. Invasive procedures to visualize and study the brain are very dangerous to an individual and can cause many problems with the brain. Functional MRI’s are used to produce images inside the brain by a doctor or bio psychologist having an individual to ingest glucose and using the functional MRI to visualize what…...

...The Brain The Central Core of our brain is at times called the “Old Brain”, this is because the Central Core is responsible for basic functions that all other vertebrates have, such as eating, breathing and sleeping. The Central Core consists of five parts, the Medulla which regulates our breathing, heart rate and blood pressure. The Pons is responsible for the sleep-wake cycles, and the Cerebellum in controls balance, reflexes and movement. The Thalamus is a major relay center for the brain and the Peripheral Nervous System. The Hypothalamus controls the emotion and motivation and stress reactions, these are the functions that we share with all other vertebrates. The Cerebral Cortex is sometimes referred to as the “New Brain”, this is the portion of the brain that allows humans to evaluate and make complex judgments along with many other abilities theses abilities are what separates humans from other vertebrates. The Cerebral Cortex consists of four parts the Occipital lobe which is responsible for processing visual information. The Temporal lobe is responsible for many things such as smell, hearing, equilibrium, emotion, motivation, complex visual processing and some language comprehension. The Parietal lobe is responsible for the visual and spatial abilities and sensory projection and association areas. The Frontal lobe is also responsible for many functions, such as concentration, emotions, motor projection and association areas, many aspects of the personality,......

...The Brain Crystal Gartner University of Phoenix PSY 240 October 26, 2012 C Hines The brain is one of the largest and most complex organs in the human body. It is made up of more than 100 billion nerves that communicate in trillions of connections called synapses. It is the portion of the vertebrate central nervous system enclosed in the skull and continuous with the spinal cord through the foramen magnum that is composed of neurons and supporting and nutritive structures (as glia) and that integrates sensory information from inside and outside the body in controlling autonomic function (as heartbeat and respiration), in coordinating and directing correlated motor responses, and in the process of learning. The nervous system is responsible for making decisions and communication within the body. The nervous system categorized into the central and the peripheral nervous systems. The central nervous system consists of the brain and spinal cord while the periphery nervous system consists of numerous nerves. Nerves move from the brain to other parts of the body such as the nose, eyes, face and ears. They also move from the brain to the spinal cord and then to other body parts like legs, stomach and chest among others. Sensory nerves take information from the environment and transmit it to the spinal cord which finally conveys it to the brain for generation of response, which is carried by motor neurons to the other parts of the body. The brain weighs about three pounds......

...CheckPoint: Brain Studies PSY/240 Teacher: Lorry J Bradley Kimberly Roberts 10/12/2012 These are the five research methods that I chose out of our text: 1. Contrast X-Rays : Contrast x-rays involve injecting a substance into an area of the body that absorbs x-rays around the surrounding tissue. The injected substance shows the contrast between the compartment and surrounding tissue during an x-ray photograph. Cerebral Angiography is the process that uses radio opaque dye into a cerebral artery that shows the cerebral circulatory system. Contrast X-rays are beneficial to understanding mental health issues because they could find location of tumors that might cause mental abnormalities in a patient. 2. Positron Emission Tomography: Also known as PET, this type of study was the first brain imaging technique that provided images of the brain and its activity rather than just straight faced images. 2-DG is injected into the patient and if the patient is doing an activity while taking this scan, bin about 30 seconds after the injection, the scan will show the brain level that most active. This can be beneficial because it can show if parts of the brain are reacting normally or abnormally to exposures to certain activities and stimulus. 3. Muscle Tension: Muscle Tension would be considered a Biofeedback. This is a method that uses the mind to control a body function that the body regulates automatically. (1) Electromyography is the normal procedure for......

...numerous ways in studying methods of the brain. It ranges from electrical and chemical stimulation, recordings of the electrical activity from the brain, scanning and imaging techniques, and so on. The effects of electrical and chemical stimulation take place within different places in the brain that selectively affect specific psychological processes as well as psychologically active medications; anesthetics and recreational drugs). These selectively affect different mental processes because they act on the brain in different brain systems. Small amounts of psychologically active chemicals can be injected into small parts of the brain. These experimental ways have helped identify the location and function of brain systems that carry out the effects of these chemicals. Through electrical stimulation, we can only stimulate the desired part of the brain. The advances in technology have made it possible to study the internal work of the brain without having to cut into an individual’s skull. The brain scanning is the mechanical and electrical measurements of the specific activates of the brain. One example I am familiar with of a scanning technique is the MRI, or magnetic resonance imaging. It uses a magnetic field in which the individual’s head is put in place. The radio waves aimed in the brain cause certain atoms within the brain to emit signals which the computer picks up. These studying techniques can distinguish between closely related brain structures. There are a......

...The Brain The Five Major Structures of The Brain At the beginning of birth there are initially three swellings in the human brain. Once adulthood is reached the brain develops two new swellings. The forebrain and the hindbrain grow into two different swellings, this is how two more are added while becoming an adult. Once as an adult the brain consists of five structures that make up the fore, mid, and hindbrain from anterior to posterior. These five structures are the Telencephalon, the Diencephalon, the Mesencephalon (mid-brain), the Metencephalon, and the myelencephalon. Myelencecephalon The Myelencephalon is the posterior part of the brain, also known as the medulla. It is composed largely of tracts carrying signals between the brain and the rest of the body. An interesting part of the Myelencephalon is called the reticular formation. Reticular formation is a complex network of around 100 tiny nuclei that occupies the central core and also the brain stem from the posterior boundary of the Myelencephalon to the anterior boundary of the midbrain. This part of the brain even plays a role in arousal which is why it is sometimes referred to as reticular activating system. However, this term can be misleading because the nuclei of the reticular formation are involved sleep, attention, movement, the maintenance of muscle tone, and various cardiac, circulatory, and respiratory reflexes. Metencephalon The......

... * There are five major divisions which hold a specific function in the brain. These major divisions or structures are very important and can often be described or compared to neighborhoods or districts due to how they have different locations in the same area. The early development of the brain begins explaining the five major divisions and what each one does in particular. In the vertebrate embryo, the tissue that eventually develops into the CNS is recognizable as a fluid-filled tube. The first indications of the developing brain are three swellings that occur at the anterior end of this tube (Pinel, 2011). These three swellings with time develop into what is known as the forebrain, midbrain and hindbrain. Before birth, the three swellings in the neural tube become five which occur when the forebrain swelling grows into two different swellings just like the hindbrain. The five swellings then make up the brain at birth. These five sections or swellings are known as the Telencephalon, Deincephalon, Mesencephalon, Metencephalon and Myelencephalon. * The Myelencephalon, also known as the Medulla Oblongata, is located in the most posterior division of the brain (Hindbrain). The Mylencephalon is responsible for delivering signals between the brain and the entire body and responsible for reticular formation. Reticular formation is known for its net-like appearance that occupies the core of the brain stem and parts of it play a role arousal as well as other functions like......

...Journey of the brain-Birth to late adulthood Child development is crucial throughout the early years, during this time the development of the brain occurs and continues through late adulthood. The development of the brain contributes to the functioning of the body. The anatomy of the brain is made up of neurons and divided into four different lobes. The temporal, frontal, parietal, and occipital lobes control a variety of cognitive functions (Santrock, 2013). The brain controls simple functions such as fine and gross motor skills, vision, and memory. For instance the frontal lobes are involved in the voluntary movement, thinking, personality, and intentionality or purpose. The occipital lobes are responsible for vision. The temporal lobes are responsible for hearing, language processing and memory. The parietal lobes plays role in registering spatial location, attention and motor control. (Santrock, 2013). Brain development in children is vital during the early years. During the early years, children brains are active enabling children to learn a variety of information. However, as individual ages there are changes in the brain which influence cognitive functioning learned throughout the years of development. At birth the newborn’s brain is about 25 percent of its adult weight; by the 24 months the brain is about 75 percent of its adult weight (Santrock, 2013). The brain is very delicate and needs a lot of protection for its......

...Running Head: BRAIN DEVELOPMENT, GENDER, AND IQ Brain development, gender and IQ in children: A volumetric imaging study National University Understanding Young Children: Cognition and the Growing Child In partial fulfillment of ECE 652 Assignment 2.1 Dr. Brenda Sheppard-Johnson April 2010 Brain development, gender and IQ in children: A volumetric imaging study Recap The quantitative study conducted by Reiss, Abrams, Singer, Ross, and Denckla, attempts to answer the question of how brain size, and more importantly cerebral capacity, differs between genders; what, if any, correlation exists between brain morphology; and are there any patterns of age–related changes evident in during childhood. (Reiss et al., 1996, p. 1764) This is one of a few studies that utilizes volumetric imaging to “describe cerebral development and morphology” in normal, non-clinically referred children. (Reiss et al., 1996) Process 100 children between the ages of five and seventeen were given MRI scans of their brains. Of these 100 images, only 85 were used in the final data analysis due to 15 not containing the entire cerebrum in the end result. There were sixty-four females and twenty-one males. The mean ages were 10.6 and 10.7 respectively. The difference between the numbers of girls to boys was due to researchers “recruitment of gender-matched normal controls for ongoing studies of female children with specific......

...Bennett The Brian The brain is consisting of three main sections. They are the forebrain, the midbrain and the hindbrain. These are connected to the central nervous system of the spinal cord (Pinel, 2011). The three sections of the brain can be subdivided into five main structures. The forebrain is where the two main structures reside; this includes the telencephalon and diencephalon which are located within the central nervous system. The midbrain is where the mesencephalon is located along with the hindbrain; the forebrain has the two final structures which are metencephalon and myelencephalon these main structures reside within the central nervous system of the brain (Pinel, 2011). The Myelencephalon, which is known as the medulla, that is located in the hindbrain, this, is the most position part of the brain. The medulla of the brain is the main structure that can carry signals throughout the entire body (Pinel, 2011). The medulla is responsible for the reticular that controls information within the brains central nervous system. The reticular information can be a complex network of the white and gray matter; this can smooth the transition between the descending and ascending signals of the central nervous system within the myelencephalon. The reticular information affects other functions of the body that includes sleep, movements, and arousal. The myelencephalon along with its reticular information can process structures of the brain that can become more......

...The Brain- Introduction The brain is an amazing organ. It monitors, regulates, initiates basic drives, stores and retrieves information, performs intellectual functions, produces and interprets language, processes visual and auditory data, and, it's only the size of a coconut. The brain works using a vast connection of nerve cells, billions in fact, that connects with billions of other nerve cells. To get a visual of the parts of your brain, hold up your hand. Place your thumb across your palm and then close your fingers over your thumb. There is your brain. Your arm is the brain stem or messenger from the brain. The outer part of your hand is the cortex. This is where rational thinking occurs. You fingers that are bent over your thumb represent your frontal cortex. Here is where parasympathetic and sympathetic responses live as well as your executive functioning such as thoughts on right and wrong and decision-making. If you lift your fingers you see your thumb. This represents the limbic system. The limbic system is a very important part of mental health nursing. Here is where the amygdala lives which controls anger and sadness. The hippocampus is also here, which is part of memory. Overall, the limbic system controls emotion and plays a role in addiction. Notice that when you close your fingers, or your frontal lobe, over your thumb, they touch. What does that mean? Well, the limbic system and frontal cortex affect each other. Remember that the brain forms from back to...

...The Brain Terrie Oliver Axia College of University of Phoenix The Brain The brain is part of the central nervous system, which is located in the skull, and a very complex organ, with massive information data that flows throughout the body. The brain is like a hard-drive: storing daily active, awareness, memory, emotions, and reason. The brain is where decision-making is done, right, or wrong, what could have been, or should have been. The brain with all its mysterious complexities, and abilities, is one of the most study organs in the human body. The brain is divided into five divisions: the forebrain contains the Telencephalon, and the Diencephalon. In the midbrain we find the Mesencephalon, and in the hindbrain the Metencephalon, and the Myelencephalon are found. These five structures also contain divisions in their selves adding to the complexity of the human brain as we discus their functions (Pinel, 2007). The Telencephalon The Telencephalon, or cerebrum as referred to by many people, is located in the forebrain, divided into two hemispheres, is the largest of the structures, and can be compared to junction box at a train depot. Train cars are like the sensory input, and output that goes into the telencephalon, which like the junction box directs these senores, or train cars where to go. These functions could be voluntary movement, learning, solving issues, or problems, and speaking. There are other divisions found in the telencephalon and they......

...The Brain and Behavior Essay The brain is an organ that serves as the center of the nervous system in all vertebrate. The function of the brain is to exert centralized control over the other organs in the body. Contrasting the roles of behavior of the temporal and frontal lobe seems to be quite interesting. Temporal lobe is one of four major lobes of the cerebral cortex. This particular lobe is responsible for the retention of the visual memories, processing sensory, comprehending language, storing and emotions. The frontal lobe is located in the front of the brain. It contains most of the dopamine sensitive neurons in the cerebral cortex. It has similarities of the temporal lobe. Some of the behaviors that the frontal lobe is responsible for are conscious thought, voluntary movement and a person individual personality characteristics. Any damages to either frontal can cause a change in a person’s emotions, they become less motivated to do anything and they become very aggressive in their behavior. Paul Broca did a study that involved language in 1861.His first studied was a deceased patient that had a problem that caused him not to speak nor express his thoughts in writing. He came to find out the he had a small size lesion on the left inferior frontal cortex. After several other studies he discovered that they all had a small lesion and this is when he made the statement “We speak with the left hemisphere” and identify the existence of a “language centre” in the posterior......

...The brain is the most complex organ in the human body. The brain produces our every thought, action, memory, and feeling. It controls our voluntary movements, and it regulates involuntary activities such as breathing and heartbeat. The Brain is a jelly like mass of tissue, weighing in at around 3 pounds, and constitutes about 2 percent of total body weight but uses 20 per cent of the oxygen used by the entire body when at rest. The brain can go without oxygen for only three to five minutes before serious damage results. The brain contains a staggering one hundred billion nerve cells, or neurons. The left hemisphere of the brain controls the right side of the body while the right hemisphere of the brain controls the left side of the body. Our brains are made mostly of water 78 percent, fat 10 percent, and protein 8 percent. A living brain is so soft that you could cut it with a butter knife. The brain is not just a mass of tissue; the brain serves as the seat of human consciousness: it stores our memories, enables us to feel emotions, and gives us our personalities. In short words the brain dictates the behaviors that allow us to survive and makes us who we are. The brain consists of three major divisions: (1) the massive paired hemispheres of the cerebrum, which include the Frontal, Parietal, Occipital, and Temporal Lobes on the left and right hemispheres. (2) The brainstem, consisting of the thalamus, hypothalamus, epithalamus, subthalamus, midbrain, pons, and medulla...

...The Brain The brain is one of the most complex and magnificent organs in the human body. Our brain gives us awareness of ourselves and of our environment, processing a constant stream of sensory data. It controls our muscle movements, the secretions of our glands, and even our breathing and internal temperature. Every creative thought, feeling, and plan is developed by our brain. The brain’s neurons record the memory of every event in our lives. Anatomy of the brain There are different ways of dividing the brain anatomically into regions. Let’s use a common method and divide the brain into three main regions based on embryonic development: the forebrain, midbrain and hindbrain. Under these divisions: The forebrain (or prosencephalon) is made up of our incredible cerebrum, thalamus, hypothalamus and pineal gland among other features. Neuroanatomists call the cerebral area the telencephalon and use the term diencephalon (or interbrain) to refer to the area where our thalamus, hypothalamus and pineal gland reside. The midbrain (or mesencephalon), located near the very center of the brain between the interbrain and the hindbrain, is composed of a portion of the brainstem. The hindbrain (or rhombencephalon) consists of the remaining brainstem as well as our cerebellum and pons. Neuroanatomists have a word to describe the brainstem sub-region of our hindbrain, calling it the myelencephalon, while they use the word metencephalon in reference to......
