Most medicines today were developed using trial-and-error techniques, which often do not reveal why a drug produces a particular effect. But the expanding knowledge gained from molecular biology methods makes safer and more effective drugs possible.

As our understanding of the processes that underlie brain damage progresses, it becomes possible to use small-molecule drugs, such as antibiotics and anti-tumor drugs, to alter these processes.

Chemical reactions within brain cells translate the neurotransmitter message for the neuron.

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.

Genes and the environment converge powerfully during early sensitive windows of brain development to form the neural circuits underlying behavior. Although most neuronal cell death occurs in the embryo, the paring down of connections occurs in large part during critical periods in early postnatal life.

Celebrate the brain year-round with interactive events and community outreach. Brain Awareness Week is March 12-18, 2018.

One of the preeminent U.S. science competitions emphasizing problem-solving and hands-on activities.

This booklet describes the symptoms of anxiety disorders, explains the role of research in understanding the causes of these conditions, describes effective treatments, and suggests ways to make treatment more effective.

In this two-part lesson by the American Association for the Advancement of Science, students learn about gelotology (the science of laughter) and its benefits to our social, mental, and physical well-being.

What happens in the brain of a person with Alzheimer's disease? This tour by the Alzheimer's Association explains how the brain works and how Alzheimer's affects it.
