Neurobiology is the branch of biology that focuses on the structure and function of the nervous system. It studies how neurons, the basic building blocks of the nervous system, communicate with each other and how they influence behavior, thoughts, and emotions. This field combines aspects of biology, psychology, and medicine to understand how the brain and spinal cord operate. Researchers in neurobiology explore various topics, including neurotransmitters, which are chemicals that transmit signals between neurons, and neuroplasticity, the brain's ability to adapt and change throughout life. By studying these processes, scientists aim to uncover the underlying mechanisms of neurological disorders and develop potential treatments.
