Neuroscience examines the structure and function of the human brain along with the nervous system. To map the brain at a mechanical level, neuroscientists use cellular and molecular biology, anatomy and physiology, human behavior and cognition, and other disciplines. 

Humans have around a hundred billion neurons, or brain cells, each with around a thousand connections to other cells. Mapping out all the networks of cell-to-cell communication is one of the greatest challenges of modern neuroscience. The result of connecting all the circuits that process thoughts, feeling, and behaviors is known as “the connectome”. The brain’s ability to elaborate new connections and neuronal circuits underlies all learning. 

Biology and psychology work together in the field of neuroscience in order to tackle questions such as the brain’s role in perceiving pain or the underlying cause of Parkinson’s disease. Computer simulation and other tools allow researchers and medical experts new insight into the physical anatomy of the brain and its relationship to the rest of the body. 

One of the current major objectives of neuroscience research is to figure out how the wiring of the brain works and what happens when it’s damaged. New developments in brain scanning technologies allow researchers to see more detailed images of the brain which allows them to determine where and how damage in wiring affects motor skills and cognitive behavior in conditions like multiple sclerosis and dementia. 

In a rapidly expanding field, neuroscience findings have exploded over the past half-century. However, more work will always be needed to fully understand the neural roots of human behavior, consciousness, and memory.
