Document Summary

Cerebral cortex: gray matter: superficial cortical layer of gray matter containing neuronal cell bodies. Cerebral white matter: deeper layer of white matter containing fibers connecting cell bodies to other cortical areas and the rest of the brain, corpus callosum are between the hemispheres, connections within the hemispheres. Deep gray matter: ganglia refers to collection of neurons in the periphery with the exception of, basal ganglia - deepest layer of large collections of neuronal cell bodies. Corpus callosum: hemisphere to the other hemisphere, the commissural fibers. Projection fibers: two types, how the cerebral cortex connects to the rest of brain (subcortical: sensory information: project into the cerebral cortex, motor information: project out from the cerebral cortex. Association fibers: short association fibers: from one gyrus to another, stay within one lobe and hemisphere, e. g. primary cortex into the association areas. Primary auditory cortex to the association area: long association fibers: go from lobe to lobe, within the same hemisphere, e. g.
