Neuroscience, also known as brain science, is a discipline dedicated to studying the structure, function, development, evolution, physiology, pharmacology, and pathology of the nervous system. Human memory, learning, perception, movement, motivation, and emotions are all closely linked to neuroscience. Current research primarily focuses on neural system molecules, the growth and development of brain neurons, cell differentiation, neuronal apoptosis, as well as various neurological disorders and diseases of the nervous system.
