ABSTRACT
Neuroscience is the scientific study of the brain and nervous system. It is a large field and immediately splits into four subfields. Neuroanatomy is the scientific study of the form and structure of the brain and nervous system. Neurophysiology is the scientific study of the physical and biochemical processes of the brain and nervous system. Neuropsychology is the scientific study of the relationships between, on the one hand, the brain and nervous system and, on the other, perceptual, interoceptive, proprioceptive, affective and cognitive processes and functions. Neuropsychiatry is the scientific study of neuropsychological dysfunctions. Given these distinctions, we can put the relations between the subfields like this: neurophysiology studies the physical and biochemical processes that neuroanatomically identified things enter into, neuropsychology studies the psychological functions of neurophysiologically identified processes, and neuropsychiatry studies dysfunctions of neuropsychologically identified processes.
