Researchers discover how antipsychotic drugs manage symptoms of schizophrenia

The classic symptoms of schizophrenia - paranoia, hallucinations, the inability to function socially-can be managed with antipsychotic drugs. But exactly how these drugs work has long been a mystery.

New mouse brain atlas provides insight into how genes work in cerebral cortex

A new atlas of gene expression in the mouse brain provides insight into how genes work in the outer part of the brain called the cerebral cortex. In humans, the cerebral cortex is the largest part of the brain, and the region responsible for memory, sensory perception and language.

Repeated cocaine use can increase individual's risk of mood disorders

It is well established that a mood disorder can increase an individual's risk for substance abuse, but there is also evidence that the converse is true; substance abuse can increase a person's vulnerability to stress-related illnesses.

Scientists generate stem cells from one of the most rapidly progressing forms of Parkinson's

Scientists have for the first time generated stem cells from one of the most rapidly progressing forms of Parkinson's disease.

Risk of Parkinson's disease increases with traumatic brain injury and exposure to pesticide paraquat

Traumatic brain injury has entered the public's consciousness as the silent, signature wound brought back by many of our military warriors from Iraq and Afghanistan. But such injuries don't only happen in warfare, they happen to civilians too. Think car crashes, a slip and fall, two football players colliding helmet to helmet.

Cellular pathology of Lou Gehrig’s disease discovered

Researchers claim to have found a common cause behind the mysterious and deadly affliction of amyotrophic lateral sclerosis, better known as Lou Gehrig’s disease. The discovery could pave the way to new treatments for the devastating disorder whose victims include top physicist Professor Stephen Hawking.

Study: Eye contact seems to act as an invitation for mimicry

Imitation may be the sincerest form of flattery but how do our brains decide when and who we should copy? Researchers from The University of Nottingham have found that the key may lie in an unspoken invitation communicated through eye contact.

New measurement technologies provide scientists more complete look at neurological activity

In 1991, Carl Lewis was both the fastest man on earth and a profound long jumper, perhaps the greatest track-and-field star of all time in the prime of his career. On June 14th of that year, however, Carl Lewis was human. Leroy Burrell blazed through the 100-meters, besting him by a razor-thin margin of three-hundredths of a second. In the time it takes the shutter to capture a single frame of video, Lewis's three-year-old world record was gone.

SIGMAR1 gene mutation associated with development of juvenile ALS

Researchers from the Kingdom of Saudi Arabia have identified a mutation on the SIGMAR1 gene associated with the development of juvenile amyotrophic lateral sclerosis.

Research: p38α MAPK protein plays a role in addiction, depression-like behavior

Researchers studying mice are getting closer to understanding how stress affects mood and motivation for drugs.

Insight into how neural circuit forms motor plan

The voluntary movements we make must be "prepared" in our brain before they are executed. However, be it perfect timing, a false-start, or a delayed reaction, the neural circuitry underlying movement preparation is not well understood.

New research uncovers role of p38alpha in mood disorders, addiction

Stressful experiences increase addictive drug consumption and can precipitate bouts of anxiety or depression in vulnerable people. Although the mechanisms linking stress and human behaviors are not well understood, animal models of some aspects of these behaviors have been developed and have been used to define some of the molecular events that may be responsible for stress vulnerability in people.

Researchers helps explain how the adult brain cleans out dead brain cells and produces new ones

Adult brains generate thousands of new brain cells called neurons each day; however only a small fraction of them survive. The rest die and are consumed by scavenger cells called phagocytes. Until now, scientists have not fully understood how this process works, which phagocytes are unique in the brain, and how the removal of dead neurons influences the production of new neurons.

Human brain cells created from skin cells: Potential for Alzheimer’s

This feat comes a year after researchers at Stanford University performed the same feat in mice, turning cells from the rodents' skin into neurons. The lab-created brain cells act the same as normal human brain cells, the researchers found. These cells have the same ability to send electric signals; they seem to express the same genes in the same ways; and they are able to communicate with other brain cells, as demonstrated in a lab dish and when implanted into mice.

UH undergraduates seek solutions to many maladies like diabetes, Alzheimer's

Students from a variety of majors are devoting their summers to serious research at the University of Houston (UH), seeking eventual solutions to many serious maladies that include Alzheimer's, high blood pressure and cholesterol, diabetes, alcoholism and anxiety.

Nacolepsy drugs may be effective in reversing illness-induced lethargy

A signaling system in the brain previously shown to regulate sleep is also responsible for inducing lethargy during illness, according to research conducted at Oregon Health & Science University Doernbecher Children's Hospital.

Scientists study how nervous system translates sensory information into coordinated motor output

Escape responses are some of the most studied behaviors by neurobiologists who want to understand how the brain processes sensory information. The ability to evade predators plays a vital role in the process of natural selection.

New software tools for fast, accurate reconstruction of neural networks

The human brain is the most complex of all organs, containing billions of neurons with their corresponding projections, all woven together in a highly complex, three-dimensional web. To date, mapping this vast network posed a practically insurmountable challenge to scientists.

Drug to prevent brain ageing: Study

A new study shows that some chemicals given to rhesus macaques blocked a brain molecule that slows the firing of the brain's nerve cells, or neurons, as they age—prompting those nerve cells to act young again.

Arterial spin labeling shows areas of brain activity in chronic low back pain patients

Research from Brigham and Women's Hospital (BWH) uses a new imaging technique, arterial spin labeling, to show the areas of the brain that are activated when patients with low back pain have a worsening of their usual, chronic pain.
