Neuroscience is a field of study which deals with the structure , function, development , genetics , biochemistry , physiology , pharmacology and pathology of the nervous system . The study of behavior and learning is also adivision of neuroscience.
The biological study of the human brain is an interdisciplinary field which involvesmany levels of study, from the molecular level through the cellular level (individual neurons ), the level of relatively small assemblies of neurons like cortical columns, that of larger subsystems likethat which subserves visual perception , up to large systems likethe cerebral cortex or the cerebellum , and at the highest level the nervous system as a whole.
At this highest level, neuroscientific approaches combine with cognitive science to create cognitive neuroscience , a discipline first populated mostly by cognitive psychologists , currently becoming a dynamic specialty of its own. Some researchersbelieve that cognitive neuroscience provides a bottom-up approach to understanding the mind and consciousness that is complementary to, or may replace, the top-downapproach of psychology .
The concern of neuroscience includes such diverse topics as
