Bigger brain size matters for intellectual ability
Brain size matters for intellectual ability and bigger is better, McMaster University researchers have found. view more (2005-12-23)
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)
New methods for brain research
Novel methods of measuring magnetic fields outside the head give further insights to the functioning of the human brain. In his doctoral thesis "Estimating Neural Currents from Neuromagnetic Measurements", Kimmo Uutela developed new methods for finding electrical activity of the brain, which enable easier identification of different... view more...

Heightened level of amygdala activity may cause social deficits in autism
Something strange is going on in the amygdala - an almond-shaped structure deep in the human brain - among people with autism. view more (2009-03-20)
Neural stem cells reduce Parkinson's symptoms in monkeys
Primates with severe Parkinson's disease were able to walk, move, and eat better, and had diminished tremors after being injected with human neural stem cells. view more (2007-06-13)
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)
New brain cells listen before they talk
Newly created neurons in adults rely on signals from distant brain regions to regulate their maturation and survival before they can communicate with existing neighboring cells-a finding that has important implications for the use of adult neural stem cells to replace brain cells lost by trauma or neurodegeneration, Yale School of Medicine... view more...

Daytime light exposure dynamically enhances brain responses
Exposure to light is known to enhance both alertness and performance in humans, but little is understood regarding the neurological basis for these effects, especially those associated with daytime light exposure. view more (2006-08-22)
UCF Research Links Protein, Stem Cells and Potential Alzheimer's Treatment
A team of scientists led by professor Kiminobu Sugaya at the University of Central Florida may have found a new way to treat Alzheimer's disease. view more (2007-08-07)
University of Manchester develops vision chip for new generation of 'human' robots
The University of Manchester is to help develop a new generation of robots with 'human' instincts. view more (2005-05-18)
Family history of brain tumors linked to increased risk of brain cancer
People with a family history of cancerous brain tumors appear to be at higher risk of developing the same kind of tumors compared to people with no such family history. view more (2008-09-22)
Memory uses separate information pathways
The researchers studied two signals from different sensory parts of the brain, one of which arrived at the perirhinal and the other at the postrhinal cerebral cortex. These parts of the brain are located close to the sulcus and receive information from areas of the brain which process different types of sensory information. The information enters... view more...

Scientists close in on genes responsible for Parkinson's disease
Scientists have identified 570 genes that act abnormally during the development of Parkinson's Disease, a finding which could help doctors predict the likelihood of it developing, and provide targets for new treatments. view more (2005-12-20)
Bacteria design new plastic
A recently discovered group of chemicals could pave the way to better plastics for surgical implants that are more compatible to the human body and less likely to become infected by disease-causing microbes. A paper published in the January issue of Microbiology describes the unusual properties of polythioesters (PTEs) and how they were... view more... (2001-01-19)
New Brain Test to Monitor Alzheimer's Disease
A new test that taps brain records so accurately it caught out a serial killer, could soon be used by pharmaceutical companies to speed up approval of drugs for Alzheimer's and other brain diseases, reports Marina Murphy in Chemistry & Industry Magazine. 'Brain Fingerprinting' is the patented technology that can measure objectively, for the... view more... (2004-03-15)
Researchers identify target for therapeutic drugs to fight most common adult brain cancer
A research team at UT Southwestern Medical Center has discovered a cell-signaling mechanism instrumental in the most common brain cancer in adults. view more (2006-01-16)
Do bilingual persons have distinct language areas in the brain?
A new study carried out at the University of Haifa sheds light on how first and second languages are represented in the brain of a bilingual person. view more (2009-07-08)
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)
The immune system and Alzheimer's disease
Utrecht researchers, funded by NWO, have determined the role played by brain cells from the immune system that are located close to dying memory cells. The research will help determine the causes of Alzheimer's disease. In patients with Alzheimer's disease, the brain cells die off. The death of these neurones takes place primarily in the vicinity... view more... (2001-11-27)
Aging brain reduces ovulation
Dutch researcher Annelieke Franke has discovered that the aging of the brain adversely affects the fertility of female rats. The scientist suspects that her research will provide insights into fertility problems of women over the age of 30. Franke studied relatively young subfertile rats. Although the pituitary gland and ovaries of these rats... view more... (2003-10-10)
