Brain's reward circuit activity ebbs and flows with a woman's hormonal cycle
Fluctuations in sex hormone levels during women's menstrual cycles affect the responsiveness of their brains' reward circuitry, an imaging study at the National Institute of Mental Health (NIMH), a component of the National Institutes of Health (NIH), has revealed. view more (2007-02-05)

Key to longer life (in flies) lies in just 14 brain cells
Two years ago, Brown University researchers discovered something startling: Decrease the activity of the cancer-suppressing protein p53 and you can make fruit flies live significantly longer. view more (2007-09-21)
No strong evidence linking amateur boxing with long-term brain injury
The evidence linking amateur boxing and chronic traumatic brain injury is not strong, concludes a study published on bmj.com today. As such, the researchers say they cannot firmly prove nor reject the theory that amateur boxing leads to chronic brain injury. view more (2007-10-08)
For The First Time, Patterns Of Excitation Waves Found In Brain's Visual Processing Center
Neuroscientists have long believed that vision is processed in the brain along circuits made up of neurons, similar to the way telephone signals are transferred through separate wires from one station to another. view more (2007-08-01)
Brain shows humans break down events into smaller units
In order to comprehend the continuous stream of cacophonies and visual stimulation that battle for our attention, humans will breakdown activities into smaller, more digestible chunks, a phenomenon that psychologists describe as "event structure perception." view more (2007-05-02)
Your brain cells may 'know' more than you let on by your behavior
We often make unwise choices although we should know better. Thunderstorm clouds ominously darken the horizon. We nonetheless go out without an umbrella because we are distracted and forget. view more (2005-10-20)
Mapping the neural landscape of hunger
The compelling urge to satisfy one's hunger enlists structures throughout the brain, as might be expected in a process so necessary for survival. view more (2006-08-17)
Brain imaging reveals breakdown of normal emotional processing
Brain imaging has revealed a breakdown in normal patterns of emotional processing that impairs the ability of people with clinical depression to suppress negative emotional states. view more (2007-08-17)
Neurons for numerosity: Parietal neurons 'sum up' individual items in a group
As any child knows, to answer the question "how many," one must start by adding up individual objects in a group. view more (2007-07-24)
Sudden death from stress linked to wonky signals in the brain
Sudden cardiac death from emotional stress may be triggered by uneven signals from the brain to the heart, according to a study by University College London (UCL) scientists published in the January issue of Brain. view more (2004-12-23)
Research finds older women who are more physically fit have better cognitive function
New research published in the international journal Neurobiology of Aging by Marc Poulin, PhD, DPhil, finds that being physically fit helps the brain function at the top of its game. view more (2009-01-09)
Learning to shape your brain activity
A study in the Oct. 1 issue of the journal Sleep shows that the successful manipulation of sensorimotor rhythm (SMR) amplitude by instrumental SMR conditioning (ISC) improved sleep quality as well as declarative learning. ISC might thus be considered a promising non-pharmacological treatment for primary insomnia. view more (2008-10-01)
Research links 'ecstasy' to survival of key movement-related cells in brain
New research from the University of Cincinnati (UC) suggests that the widely abused club drug "ecstasy," or MDMA, can increase the survival of dopamine cells in the brain during fetal development. view more (2006-10-19)
Pharmaceutical market fails pregnant women; and more
In a clinical trial published this week in PLoS Medicine, Charles Sawyers and colleagues looked at the safety of a drug called rapamycin in a selected group of patients who were undergoingsurgery after recurrence of glioblastoma (a highly malignant tumor of the brain). view more (2008-01-22)
Study Indicates How We Maintain Visual Details In Short Term Memory

Postmortem data support link between gene and schizophrenia
We have known for a long time that there is a genetic component to schizophrenia, but nailing down the gene(s) has not been easy. view more (2005-09-13)
Sitting and thinking, or just sitting?
Patients recovering from brain injuries such as strokes often experience difficulties carrying out two activities at the same time, according to researchers in the School of Psychology at the University of Reading. Most of us can walk, cycle or drive and carry on a conversation at the same time because the combination of motor actions is so... view more... (2004-03-19)
Brain's magnetic fields reveal language delays in autism
Faint magnetic signals from brain activity in children with autism show that those children process sound and language differently from non-autistic children. view more (2008-12-01)
Research shows how genetic mutation causes epilepsy in infants
New research from the Howard Florey Institute in Melbourne has shown why mutation in a single gene can cause epilepsy in infants. view more (2007-10-04)
