Chapter 1: Introduction An understanding of functional neuroanatomy is critical to understanding the symptoms of nervous system damage. Most disorders of the nervous system either target particular brain structures or target components of functional systems. Therefore, knowing these structures and their basic functions permits localization of the nervous system damage. This chapter will consider the important elements of clinical neuroanatomy. There are several good texts that provide greater detail on these systems (1-3). Brain Structures and Their Functions The nervous system is your body's decision and communication center. The central nervous system (CNS) is made of the brain and the spinal cord and the peripheral nervous system (PNS) is made of nerves. Together they control every part of your daily life, from breathing and blinking to helping you memorize facts for a test.
Autism and Neuropsychology, by Marisa Marzillo Autism is a lifelong disorder that has become the discussion of many media outlets; it is a disorder that causes abnormal neurological development. It seems that lately autism prevalence is increasing, which is causing a demand for professionals to investigate on what causes autism. Autism disorder is characterized by different behavior including social impairments, difficulty in communication, and restrictive patterns of behavior. Individuals living with autism don’t have a lower IQ than most people, but it is common that they have weak social interaction. Researchers have stated that it is unclear what causes autism; it ranges from environmental surroundings to a strain on normal brain development.
Santiago Ramón y Cajal Santiago Ramón y Cajal ForMemRS (Spanish: [sanˈtjaɣo raˈmon i kaˈxal]; 1 May 1852 – 18 October 1934) was a Spanish pathologist, histologist, neuroscientist and Nobel laureate. His original pioneering investigations of the microscopic structure of the brain have led him to be designated by many as the father of modern neuroscience. His medical artistry was legendary, and hundreds of his drawings illustrating the delicate arborizations of brain cells are still in use for educational and training purposes. An afternoon nap markedly boosts the brain’s learning capacity If you see a student dozing in the library or a co-worker catching 40 winks in her cubicle, don’t roll your eyes. New research from the University of California, Berkeley, shows that an hour’s nap can dramatically boost and restore your brain power. Indeed, the findings suggest that a biphasic sleep schedule not only refreshes the mind, but can make you smarter. Students who napped (green column) did markedly better in memorizing tests than their no-nap counterparts. (Courtesy of Matthew Walker)
Chapter 9: Limbic System The limbic system is a convenient way of describing several functionally and anatomically interconnected nuclei and cortical structures that are located in the telencephalon and diencephalon. These nuclei serve several functions, however most have to do with control of functions necessary for self preservation and species preservation. They regulate autonomic and endocrine function, particularly in response to emotional stimuli. They set the level of arousal and are involved in motivation and reinforcing behaviors.

They influence the way information is processed in the brain and can occur early during sensory processing. Balint's syndrome is a visual attention and awareness deficit. Someone who has this syndrome can only perceive one object at a time.
The Brain's Dark Energy Imagine you are almost dozing in a lounge chair outside, with a magazine on your lap. Suddenly, a fly lands on your arm. You grab the magazine and swat at the insect. What was going on in your brain after the fly landed? Brain Function, Anatomy & Diagram Much of the brain's job involves receiving information from the rest of the body, interpreting that information, and then guiding the body's response to it. Types of input the brain interprets include odors, light, sounds, and pain. The brain also helps perform vital operations such as breathing, maintaining blood pressure, and releasing hormones. The brain is divided into sections. These sections include the cerebrum, the cerebellum, the diencephalon, and the brain stem.
Neurophysiology Neurophysiology (from Greek νεῦρον, neuron, "nerve"; φύσις, physis, "nature, origin"; and -λογία, -logia) is a branch of physiology and neuroscience that is concerned with the study of the functioning of the nervous system. The primary tools of basic neurophysiological research include electrophysiological recordings such as patch clamp and calcium imaging, as well as some of the common tools of molecular biology. Neurophysiology is connected with electrophysiology, neurobiology, psychology, neurology, clinical neurophysiology, neuroanatomy, cognitive science, biophysics, mathematical biology, and other brain sciences. History How Our Brains Make Memories Sitting at a sidewalk café in Montreal on a sunny morning, Karim Nader recalls the day eight years earlier when two planes slammed into the twin towers of the World Trade Center. He lights a cigarette and waves his hands in the air to sketch the scene. At the time of the attack, Nader was a postdoctoral researcher at New York University.
