Neurobiology is the study of the nervous system and its impact on behavior and cognitive functions. It encompasses various aspects of biology, psychology, and physiology, focusing on how neurons and neural circuits operate. Researchers in this field aim to understand the complex interactions that govern brain function and behavior. This discipline also explores the molecular and cellular mechanisms underlying neural processes. By studying neurons, synapses, and neurotransmitters, neurobiologists seek to uncover the biological basis of learning, memory, and emotions, contributing to advancements in treating neurological disorders such as Alzheimer's disease and Parkinson's disease.
