The Cerebrum is the largest and “newest" part of the human brain and is made up of the cortex. Major regions of the cortext are responsible for the processing of our sensations, how we receive the world. The Frontal Lobe is implicated in motor control, complex thoughts, associations, and social thinking. It's important to understand that each lobe of the brain does not function alone. There are very complex relationships between the lobes of the brain and between the right and left hemispheres.. The cerebrum is divided into four lobes: frontal, parietal, temporal, and occipital. This lesson introduces you to the most marvelous and mysterious part of your anatomy — the human brain. Many people never totally discover or exert the full potential of their brain. In this lesson you will explore current research on what the brain is. (structure) and how it works (function). You'll learn practical ways to apply. What makes the human brain unique is its size. Our brains have a larger cerebral cortex, or cerebrum, relative to the rest of the brain than any other animal. (See the Cerebrum. In this fact sheet: • The purpose of this fact sheet is to give a concise overview of some of the key parts of the brain and to outline their functions. In this booklet, we describe what we know about how the brain works and how much there still is to learn. Its study involves scientists and medical doctors from many disciplines, ranging from molecular biology through to experimental psychology, as well as the disciplines of anatomy, physiology and pharmacology.

However, such a distinction would be possible only if sex/gender differences in brain features were highly dimorphic (i.e., little overlap between the forms of these features in males and. Functional Brain Imaging and Human Brain Function. Marcus E. Raichle. Washington University School of Medicine, St. Louis, Missouri 63110. Introduction.

The brain is an organ that serves as the center of the nervous system in all vertebrate and most invertebrate animals.

In his recent book J. B. Hellige states: "Individuals differ from each other in patterns of hemispheric asymmetry and in the ways that the two hemispheres interact. In the past, much of this individual variation was treated as random. Virtually all domains of cognitive function require the integration of distributed neural activity.

It regulates all of our physical and mental functions and shapes who we are. This six-week course explores this remarkable organ: how it has evolved, how it works and how it changes over the course of our lives. Each week, participants will draw from essays, media. The nervous system—in particular, the brain and its cognitive abilities—is among humans' most distinctive and impressive attributes. How the nervous system has changed in the human lineage and how it differs from that of closely related primates is not well understood. Here, we consider. How to increase serotonin in the human brain without drugs. Simon N. Young, PhD. Editor-in-chief, Journal of Psychiatry and Neuroscience, and Department of Psychiatry, McGill University, Montréal, Que. For the last 4 decades, the question of how to manipulate the serotonergic system with drugs has been an important. To relate behavioural function to anatomy using the lesion approach, it is necessary to identify the location and extent of a brain injury.
