Concerned about how many brain cells you've killed? Don't be, you are constantly regenerating them. Around a decade ago, researchers put an end to the myth that we were born with a set number of brain cells. More recent discoveries show exercise is the best way...
PARIS AFP — Researchers may have found the reason why children who go to bed too late often fare badly at school: lack of sleep appears to disrupt functioning of the hippocampus, an area of the brain that formulates new memories. Reporting Sunday in the journal Nature Neuroscience, Harvard...
Byline: Andy Coghlan Dec 06, 2006 (New Scientist - ABIX via COMTEX) -- Researchers at Princeton University studied the effect of sleep deprivation on rats. They found that stress hormones built up in the hippocampus, which impeded the growth of the cells responsible for...
Jun 24, 2003 (The Economist - ABIX via COMTEX) Neuroscience and bioengineering scientists are devising "brain prostheses" and "neural interfaces". They are looking for cures for brain-related disorders such as epilepsy, as opposed to trying to create an artificial consciousness. Testing of an artificial...
This paper prospectively explored whether a reduction in the volume of the hippocampus occurs in recent trauma survivors who develop posttraumatic stress disorder PTSD. Smaller hippocampal volume is not a necessary risk factor for developing PTSD and does not occur within 6 months of expressing the disorder. This brain abnormality...
OTTAWA AFP — Canadian researchers have discovered that smoking marijuana could improve a person's memory and mood. A team at the University of Saskatchewan headed by Xia Zhang found that injections of a potent HU210 synthetic substance that mimics the active ingredients in cannabis increases the production of neurons...
STANFORD, Calif. -- Severe stress can damage a child's brain, say researchers at the Stanford University School of Medicine and Lucile Packard Children's Hospital. The researchers found that children with post-traumatic stress disorder and high levels of the stress hormone cortisol were likely to experience a decrease in the size...
Neurome, Inc. recently completed the second phase of its analysis of Elan's mouse model of Alzheimer's disease AD, which is to be published today in the Proceedings of the National Academy of Sciences of the United States of America PNAS, Vol. 100, No. 8, pp. 4837-4842 (2003). The paper...
The corpus callosum, the largest white matter tract in the brain, is a midline structure associated with the formation of the hippocampus, septum pellucidum, and cingulate cortex, which have been implicated in the pathogenesis of schizophrenia. Corpus callosum shape deformation, therefore, may reflect a midline neuro developmental abnormality. Corpus callosum...
In animals, exposure to severe stress can damage the hippocampus. Recent human studies show smaller hippocampal volume in individuals with the stress-related psychiatric condition posttraumatic stress disorder PTSD. Does this represent the neurotoxic effect of trauma, or is smaller hippocampal volume a pre-existing condition that renders the brain more vulnerable...
M2 PRESSWIRE-14 May 1999-US DEPT OF HHS: NICHD researchers discover gene for major brain structure C1994-99 M2 COMMUNICATIONS LTD RDATE:140599 Researchers at the National Institute of Child Health and Human Development NICHD have discovered a gene that controls the development of...
Evidence suggests that some structural brain abnormalities in schizophrenia are neuro developmental in origin. There is also growing evidence to suggest that shape deformations in brain structure may reflect abnormalities in neurodevelopment. While many magnetic resonance MR imaging studies have investigated brain area and volume measures in schizophrenia, fewer have...
How to Boost Your Memorygood infoThis is some good information. Part of my problem with memory is my lack of concentration and focus when I am dealing with several issues or things that I want to accomplish. Does anyone have any advice on how to concentrate more when...
