- 1. Systems neuroscience is a multidisciplinary scientific field that seeks to understand the principles and mechanisms underlying complex brain functions. It integrates knowledge from various disciplines such as neuroscience, psychology, computer science, and engineering to study how neural circuits process information and generate behavior. By examining the interactions between different brain regions and how they give rise to perception, cognition, and action, systems neuroscience aims to unravel the mysteries of the brain and ultimately improve our understanding of brain disorders and develop new treatments.
