The complicated, multidisciplinary, and quickly developing field of neuroscience looks at the structure and function of the human brain and nervous system. Neuroscience research draws on cellular and molecular biology, anatomy and physiology, human behavior and cognition, and other disciplines, to tool out information about how the brain works at levels previously unrecognized. We have a hundred billion neurons, or brain cells, with close to a quadrillion connections between them, and we have yet to fully understand a single cell.
Neuroscience is the place where psychology meets biology to further our understanding of physical, psychological, and neurological health conditions, such as the brain’s role in how we perceive different types of pain and the underlying cause of Parkinson’s disease. Computer simulations, imaging, and other tools give researchers and medical experts new insight into the physical anatomy of the brain and its relationship to the rest of the mind and body.
