One of the most common and least understood neurobiological disorders, Tourette syndrome is an inherited disorder that affects about 200,000 Americans. Males are affected three to four times as often as females.

PET is one of the most important techniques for measuring blood flow or energy consumption in the brain. This method of measuring brain function is based on the detection of radioactivity emitted when positrons, positively charged particles, undergo radioactive decay in the brain.

Our best insights into how the normal brain ages come from long-term studies of the nervous system that began decades ago.

Insulation covering wires preserves the strength of the electrical signals that travel through them. The myelin sheath covering axons serves a similar purpose.

Much as vaccinations eradicated many destructive diseases in the past, neuroscientists are engineering antibodies to try and treat degenerative diseases such as Alzheimer's and Parkinson's.

A major breakthrough in understanding how the brain accomplishes learning and memory began with the study of a person known by his initials, H.M.

Cells within the nervous system, called neurons, communicate with each other in unique ways. The neuron is the basic working unit of the brain.

Brain injury is all too common, but treatments are being improved constantly. Those who survive a brain injury face a lifetime of disability, with economic costs approaching $60 billion annually.

Currently approved treatments for Alzheimer’s disease do not modify the course of the disease and offer only temporary mitigation of some symptoms, such as agitation, anxiety, unpredictable behavior, sleep disturbances, and depression.

Processing information from the sensory systems is one of many functions of the brain. Such information is often the first step in other brain activities, including learning and retaining knowledge.
