Scientists Discover Hunger's Timekeeper

(PhysOrg.com) -- Researchers at Columbia and Rockefeller Universities have identified cells in the stomach that regulate the release of a hormone associated with appetite. The group is the first to show that these cells, ...

Exercise helps treat addiction by altering brain's dopamine system

New research by the University at Buffalo Research Institute on Addictions has identified a key mechanism in how aerobic exercise can help impact the brain in ways that may support treatment—and even prevention strategies—for ...

Scientists explain how ketamine vanquishes depression within hours

(Medical Xpress)—Many chronically depressed and treatment-resistant patients experience immediate relief from symptoms after taking small amounts of the drug ketamine. For a decade, scientists have been trying to explain ...

Brain wiring quiets the voice inside your head

During a normal conversation, your brain is constantly adjusting the volume to soften the sound of your own voice and boost the voices of others in the room.

Scientists identify ALS disease mechanism

Researchers have tied mutations in a gene that causes amyotrophic lateral sclerosis (ALS) and other neurodegenerative disorders to the toxic buildup of certain proteins and related molecules in cells, including neurons. The ...

Neuroscience

Neuroscience is the scientific study of the nervous system. Such studies span the structure, function, evolutionary history, development, genetics, biochemistry, physiology, pharmacology, informatics, computational neuroscience and pathology of the nervous system.

The International Brain Research Organization was founded in 1960, the European Brain and Behaviour Society in 1968, and the Society for Neuroscience in 1969, but the study of the brain dates at least to ancient Egypt. Traditionally, neuroscience has been seen as a branch of the biological sciences. Recently, however, there has been a surge of interest from many allied disciplines, including cognitive and neuro-psychology, computer science, statistics, physics, philosophy, and medicine. The scope of neuroscience has now broadened to include any systematic, scientific, experimental or theoretical investigation of the central and peripheral nervous system of biological organisms. The empirical methodologies employed by neuroscientists have been enormously expanded, from biochemical and genetic analyses of the dynamics of individual nerve cells and their molecular constituents to imaging of perceptual and motor tasks in the brain. Recent theoretical advances in neuroscience have been aided by the use of computational modeling.
