A New Method For Assessing Neurological Development Of Fetuses? (p 779)
A preliminary study in this week's issue of THE LANCET outlines how light-emitting technology could help in the future assessment of fetal neurological development. There have been only a few studies of visual-evoked response in human fetuses, and all have focused on general changes such as heart rate, body movements, and eye movements. Curtis... view more...

Preventing overload in the brain
Brain researchers in Amsterdam have observed a double control system in the hippocampus. This double control system contributes to the memory and ensures that the brain does not `crash`, as is the case during an epileptic seizure. The neurobiologists from the University of Amsterdam carried out their observations on the hippocampus of rats. The... view more... (2002-01-29)
Hush Little Baby... Linking Genes, Brain, and Behavior in Children
It comes as no surprise that some babies are more difficult to soothe than others but frustrated parents may be relieved to know that this is not necessarily an indication of their parenting skills. view more (2009-07-14)
Rare cell prevents rampant brain activity
One of the mysteries of the brain is how it avoids ending up in a state of chaos, something which happens only on exceptional occasions, when it can lead to epileptic fits. Scientists at Karolinska Institutet have now uncovered a new mechanism controlling how the brain keeps its neuronal activity in check. view more (2007-03-05)
You will remember this
Scientists can now predict memory of an event before it even happens. A team at UCL (University College London) can now tell how well memory will serve us before we have seen what we will remember. view more (2006-02-27)
Hepatic encephalopathy and prehepatic portal hypertension rat model
A research article to be published June 21, 2009 in the World Journal of Gastroenterology addresses this question. The research team lead by Dr. Gabriela Beatriz Acosta, observed that the activity of GS was increased in the hippocampus in PH rats. view more (2009-06-29)
Not just your imagination: The brain perceives optical illusions as real motion
Ever get a little motion sick from an illusion graphic designed to look like it's moving? A new study suggests that these illusions do more than trick the eye; they may also convince the brain that the graphic is actually moving. view more (2009-02-03)
Findings on bladder-brain link may point to better treatments for problems in sleep, attention
Bladder problems may leave a mark on the brain, by changing patterns of brain activity, possibly contributing to disrupted sleep and problems with attention. view more (2008-07-30)
Flies on speed offer insight into the roles of dopamine in sleep and arousal
Methamphetamine, the drug of choice for long-distance truckers and college students pulling all-nighters, appears to do a similar trick for fruit flies, too. This finding is one of several in a new study that demonstrates a critical role for the neurotransmitter dopamine in the modulation of sleep, wake, and arousal states. view more (2005-07-12)
Hard-wiring the fruit fly's visual system
Both vertebrate and fruit fly have so-called visual maps in the brain that represent the world they see. view more (2006-09-21)
Computer obeys thoughts via Brain-Computer Interface
A research group led by Academy Professor Mikko Sams is developing a brain-computer interface, a device that transforms electrical or magnetic brain signals into commands a computer can understand. Equipment of this kind is necessary. For instance, it enables physically disabled persons to use a computer keyboard. The Brain-Computer Interface, or... view more... (2005-03-02)
Scan visualises poor memory in the elderly
Dutch psychologists have found that elderly persons with a poor memory demonstrate less activity in the mediotemporal lobe when storing new information than elderly persons with a normally functioning memory. Sander Daselaar from the Free University of Amsterdam made scans of the activity in various brain areas. These showed differences between... view more... (2003-03-21)
Scans show learning 'sculpts' the brain's connections
Spontaneous brain activity formerly thought to be "white noise" measurably changes after a person learns a new task, researchers at Washington University School of Medicine in St. Louis and the University of Chieti, Italy, have shown. view more (2009-10-09)
Study supports theory why brain-injured children often recover
The number of sites in children's brains involved in language recognition decreases as the children age, according to a University of Cincinnati (UC) study. view more (2006-04-06)
Shift in brain's language-control site offers rehab hope
Scientists have found that the site in the brain that controls language in right-handed people shifts with aging-a discovery that might offer hope in the treatment of speech problems resulting from traumatic brain injury or stroke. view more (2005-10-10)
Epsilon4 allele carriers show altered brain activity before onset of Alzheimer's symptoms
Healthy individuals who are at risk of Alzheimer's disease show reduced activity in the hippocampal region of the brain when performing tasks related to forming new memories. view more (2006-01-13)
Slow brain waves play key role in coordinating complex activity
While it is widely accepted that the output of nerve cells carries information between regions of the brain, it's a big mystery how widely separated regions of the cortex involving billions of cells are linked together to coordinate complex activity. view more (2006-09-15)
New insight into brain disorders
The function of an enzyme in the brain - strongly linked to a number of major brain diseases such as Alzheimer's, schizophrenia and bi-polar disorder - has been identified for the first time by researchers at the University of Bristol, UK. view more (2007-03-01)
Leptin has powerful effect on reward center in the brain
Leptin, a hormone critical for normal food intake and metabolism, exerts a strong effect on appetite by acting in the mid-brain region as well as in the hypothalamus. view more (2006-09-29)
Looking for something? Surprising number of neurons help find it, research shows
A person searching for a ripe tomato at the grocery store is more likely to notice apples, strawberries and other red fruits as well. view more (2007-07-19)
