New sleep-deprivation record holder Tony Wright tells Gelf he's altered his brain chemistry and thus can stay up indefinitely. On May 14, Tony Wright walked into the Studio Bar in Penzance, England. For 11 days and two hours, the long-haired horticulturist stayed there, playing pool, talking with other customers, and taking notes. One thing he didn't do, though, was sleep. When he finally left, he had broken the unofficial world record for sleep deprivation that has stood for more than 40 years.

The Key Step to Recovery, even Nationally, is to Admit we have a Problem: "Houston, we have a Problem..." We live in an "addictive age." If we would total the number of people that are addicted to gambling, drugs and alcohol, sex, eating, work, shopping, Internet, video games, pain killers, caffeine, smoking, etc. we would find ourselves in the midst of a national epidemic--and we are!
Aug. 3, 2010 — Where you grow up can have a big impact on the food you eat, the clothes you wear, and even how your brain works. In a report in a special section on Culture and Psychology in the July Perspectives on Psychological Science , a journal of the Association for Psychological Science, psychological scientists Denise C. Park from the University of Texas at Dallas and Chih-Mao Huang from the University of Illinois at Urbana-Champaign discuss ways in which brain structure and function may be influenced by culture.

The central nervous system (CNS) consists of the brain and the spinal cord, immersed in the cerebrospinal fluid (CSF). Weighing about 3 pounds (1.4 kilograms), the brain consists of three main structures: the cerebrum, the cerebellum and the brainstem. Cerebrum - divided into two hemispheres (left and right), each consists of four lobes (frontal, parietal, occipital and temporal). The outer layer of the brain is known as the cerebral cortex or the ‘grey matter’. It covers the nuclei deep within the cerebral hemisphere e.g. the basal ganglia; the structure called the thalamus, and the ‘white matter’, which consists mostly of myelinated axons. – closely packed neuron cell bodies form the grey matter of the brain.The unique ability of Dr Daniel Amen to link brain images to behavioral problems is inexplicable to a large section of the medical community. Dr.Amen has done path breaking work at the cutting edge of science in SPECT neuroimaging. He has documented links between SPECT images of neural activity and emotional problems such as depression, anxiety, temper, impulsiveness and obsession. After identifying these as “observable circuit problems,” he has successfully treated thousands of patients. Yet, in spite of his patent success, many dispute his claims. While they sneer at a “picture” of “this is what your brain looks like on drugs,” Dr.
