People with rare type of memory loss still sensitive to others, study shows

People with a devastating brain injury that has wiped out many of their personal memories may still be able to understand other people's feelings and intentions, according to a joint study by the Rotman Research Institute at the Baycrest Centre for Aging and the Brain, and York University's Department of Psychology, Faculty of Health.

Naturally occurring brain chemical acetylcholine enhances visual processing

Neuroscientists at New York University have found that a naturally occurring chemical in the brain can enhance visual processing and suggest that this chemical may represent part of the biological basis of visual attention.

Study shows how men and women differ in their neural responses to psychological stress

According to a study that appears in the current issue of SCAN (Social Cognitive and Affective Neuroscience), researchers at the University of Pennsylvania School of Medicine discuss how men and women differ in their neural responses to psychological stress.

People with migraines have differences in cortex area of the brain

People with migraines have differences in an area of the brain that helps process sensory information, including pain, according to a study published in the November 20, 2007, issue of Neurology, the medical journal of the American Academy of Neurology.

Brain compensatory mechanisms contribute to recovery from spinal cord injury

A research team led by Tadashi Isa, a professor at the Japanese National Institute for Physiological Sciences, NIPS (SEIRIKEN), and Dr. Yukio Nishimura (University of Washington, Seattle), have found that brain compensatory mechanisms contribute to recovery from spinal cord injury.

ADHD a result of delayed brain development

Scientists in the United States have discovered that youngsters with attention deficit hyperactivity disorder (ADHD) have a delay in the development of some parts of their brains.

Using neural signals to predict sensory decisions

The rodent whisker sensory system is particularly intriguing because it is "active": the animal generates sensory signals by palpating objects through self-controlled whisker motion (just as we move our fingertips along surfaces to measure their tactile features).

Researchers image a biomarker of neurogenesis

Mirjana Maletic-Savatic, M.D., Ph.D, and co-investigators from Stony Brook University Medical Center, Brookhaven National Laboratory and Cold Spring Harbor Laboratory have discovered a way to image a biomarker of neural stem and progenitor cells (NPCs) in the living human brain.

Cortex maturation in attention deficit hyperactivity disorder

In youth with attention deficit hyperactivity disorder (ADHD), the brain matures in a normal pattern but is delayed three years in some regions, on average, compared to youth without the disorder, an imaging study by researchers at the National Institutes of Health's (NIH) National Institute of Mental Health (NIMH) has revealed.

Prazosin curbs brain damage from post-traumatic stress disorder

A drug used to treat high blood pressure and enlargement of the prostate may protect the brain from damage caused by post-traumatic stress disorder, Alzheimer's disease, depression and schizophrenia.

Maternal link to Alzheimer's disease found

People who have a mother with Alzheimer's disease appear to be at higher risk for getting the disease than those individuals whose fathers are afflicted, according to a new study by NYU School of Medicine researchers.

Neural stem cells may help to restore memory after brain damage

In the study, mice with brain injuries experienced enhanced memory -- similar to the level found in healthy mice -- up to three months after receiving a stem cell treatment. Scientists believe the stem cells secreted proteins called neurotrophins that protected vulnerable cells from death and rescued memory.
