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. Nerves reach from your brain to your face, ears, eyes, nose, and spinal cord... and from the spinal cord to the rest of your body.

Primitive Brain Is 'Smarter' Than We Think, MIT Study Shows Primitive structures deep within the brain may have a far greater role in our high-level everyday thinking processes than previously believed, report researchers at the MIT Picower Center for Learning and Memory in the Feb. 24 issue of Nature. The results of this study led by Earl K. Miller, associate director of the Picower Center at MIT, have implications about how we learn. The new knowledge also may lead to better understanding and treatment for autism and schizophrenia, which could result from an imbalance between primitive and more advanced brain systems. Our brains have evolved a fast, reliable way to learn rules such as "stop at red" and "go at green."

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. The three main subjects that researchers have said are a cause of autism are brain development, genes, and environmental.

The depression map: genes, culture, serotonin, and a side of pathogens Maps can tell surprising stories. About a year ago, Northwestern University psychologist Joan Chiao pondered a set of global maps that confounded conventional notions of what depression is, why we get it, and how genes — the so-called “depression gene” in particular — interact with environment and culture. So she gathered it. Chiao and one of her grad students, Katherine Blizinsky, found all the papers they could that studied serotonin or depression in East Asian populations.

Student Nurse - A&P Anatomy and Sectional Terminology It sounds silly, but you learn as many new words in an A&P course as you do a beginning foreign language course.

What is the Hippocampus? By Dr Ananya Mandal, MD The hippocampus is a small region of the brain that forms part of the limbic system and is primarily associated with memory and spatial navigation. Anatomy and location The hippocampus is located in the medial temporal lobe of the brain, underneath the cortical surface.

Chapter 12: Attention and Consciousness Attention involves top-down (voluntary) goal-directed processes and bottom-up (reflexive), stimulus-driven mechanisms. 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. Theoretical Models of AttentionAttention is defined as the ability to attend to somethings while ignoring others.
