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.

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.

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.

The brain uses some unconventional means to communicate.

The two halves of the nervous system work together in order for your body to properly communicate its sensations and needs.

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.

Once the neural induction has occurred, the next step for new neurons is a journey to the proper position in the brain. This process is called migration, and it begins three to four weeks after a human baby is conceived.

HIV attacks the immune system’s cells that help protect the body from infection and can also lead to severe neurological disorders.
