Neuroscience

Neuroscience is the study of the nervous system, especially the brain, and how it produces thoughts, feelings, and behavior. It looks at everything from tiny cells called neurons, which send electrical and chemical signals to communicate, up to how billions of these cells work together to let you see, move, remember, and make decisions. Because it touches biology, chemistry, and psychology all at once, neuroscience helps explain both healthy brain function and what goes wrong in conditions like depression or Alzheimer's disease.
