Neuroscience
Contributed by: McLoughlin
  • 1. Neuroscience is a multidisciplinary branch of biology that focuses on the study of the nervous system, including the brain, spinal cord, and peripheral nerves. It seeks to understand how the nervous system functions at various levels, from individual cells to complex interactions between different brain regions. By investigating the structure and function of the nervous system, neuroscientists aim to uncover the mechanisms underlying various neurological processes, such as sensation, movement, learning, memory, emotion, and cognition. Advances in neuroscience have led to a deeper understanding of brain disorders and conditions, paving the way for innovative treatments and therapies to improve human health and well-being.
