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.
Gut Feelings Have you ever had a "gut feeling" about something that's later turned out to be true? Have you ever felt "open-hearted"? Ever encountered a situation that's made you "hot under the collar"? World's most detailed scans will reveal how brain works 5 March 2013Last updated at 13:27 ET By Pallab Ghosh Science correspondent, BBC News Continue reading the main story Daydream Believer: an MRI scan of the brain at rest. Resilient people more satisfied with life Public release date: 23-May-2012 [ Print | E-mail Share ] [ Close Window ] Contact: Joaquín T LimoneroJoaquin.firstname.lastname@example.org Universitat Autonoma de Barcelona When confronted with adverse situations such as the loss of a loved one, some people never fully recover from the pain. Others, the majority, pull through and experiment how the intensity of negative emotions (e.g. anxiety, depression) grows dimmer with time until they adapt to the new situation.
Short-term memory is based on synchronized brain oscillations Scientists have now discovered how different brain regions cooperate during short-term memory. Holding information within one's memory for a short while is a seemingly simple and everyday task. We use our short-term memory when remembering a new telephone number if there is nothing to write at hand, or to find the beautiful dress inside the store that we were just admiring in the shopping window.
Brain Waves The human brain is more complex than your scientists suspect. They are busily mapping where certain functions occur, and how parts of the brain activate in syncronicity. They know that parts of the brain, near the stem, are older than, for instance, the forebrain, and that a human can survive remarkably well with only half a brain, as long as that half is either the right or left, intact. But what your scientists do not know is that beyond the old brain and the new, the subconscious and the conscious, the right and the left halves - there are yet more subdivisions of the human brain. Where it is known that the brain seems to specialize in activity that requires Beta frequency brain waves during wakefulness, and Alpha frequency waves during sleep or meditation, and Theta waves during rage, and Delta waves in coma - no one is quite sure why.
Intuition May Reveal Where Expertise Resides in the Brain In the instant before he drove Kuang's sting through the base of the first tower, he attained a level of proficiency exceeding anything he'd known or imagined. Beyond ego, beyond personality, beyond awareness, he moved, Kuang moving with him, evading his attackers with an ancient dance, Hideo's dance, grace of the mind-body interface granted him, in that second, by the clarity and singleness of his wish to die. —William Gibson,Neuromancer, 1984 Sometimes a solution just appears out of nowhere. You bring your multipage spreadsheet to the finance department, and within seconds the accountant tells you something isn't quite right without being able to say what.
Sensory substitution Sensory substitution means to transform the characteristics of one sensory modality into stimuli of another sensory modality. It is hoped that sensory substitution systems can help handicapped people by restoring their ability to perceive a certain defective sensory modality by using sensory information from a functioning sensory modality. A sensory substitution system consists of three parts: a sensor, a coupling system, and a stimulator.

Schizophrenia diagnosis associated with progressive brain changes among adolescents Adolescents diagnosed with schizophrenia and other psychoses appear to show greater decreases in gray matter volume and increases in cerebrospinal fluid in the frontal lobe compared to healthy adolescents without a diagnosis of psychosis, according to a report in the January issue of Archives of General Psychiatry, one of the JAMA/Archives journals. “Progressive loss of brain gray matter (GM) has been reported in childhood-onset schizophrenia; however, it is uncertain whether these changes are shared by pediatric patients with different psychoses,” the authors write as background information in the study. Celso Arango, M.D., Ph.D., of the Hospital General Universitario Gregorio Marañón, Madrid, Spain, and colleagues, examined the progression of brain changes in first-episode early-onset psychosis and the relationship to diagnosis and prognosis at two-year follow-up among patients at six child and adolescent psychiatric units in Spain.
