Neurosciencestructure, function, development, genetics,
biochemistry, physiology, pharmacology and pathology of the
nervous system. The study of behavior and learning is also a
division of neuroscience. The biological study of the human
brain is an interdisciplinary field which involves many 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 like
that which subserves visual perception, up to large systems like
the 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 researchers believe that cognitive
neuroscience provides a bottom-up approach to understanding the
mind and consciousness that is complemen
