Neuroscientists focus on the brain and its impact on behaviour and cognitive functions. They study the nervous system's cellular, functional, behavioural, evolutionary, computational, molecular, cellular, and medical aspects.

Neuroscience is an interdisciplinary science. It works closely with mathematics, linguistics, engineering, computer science, chemistry, philosophy, psychology, and medicine.

Neuroscience affects all human functions, but it also assists in a better understanding of common conditions such as Down syndrome, Autistic spectrum disorders (ASD), ADHD, addiction, brain tumours, immune system disorders like multiple sclerosis, and Parkinson's disease.

Understanding the neurological factors can facilitate in developing medications and other strategies to treat and prevent these conditions.
