Document Summary
Psych 261 - module 3. 2 - the cerebral cortex. Cerebral cortex: most prominent part of the mammalian brain, cells on the outer surface are gray matter and axons extending inward are white matter. Neurons in each hemisphere communicate with neurons in other parts through two bundles of axons: corpus callosum. Organization of the cerebral cortex in humans and most other mammals, cerebral cortex contains up to six distinct laminae (layers of cell bodies that are parallel to the surface of the cortex and separated by layers of fibres) Laminae v: sends long axons to the spinal cord and other distant areas, has greatest control of the muscles. Laminae iv: receives axons from the sensory nuclei of the thalamus, prominent in the sensory areas of the cortex (visual, auditory, somatosensory), but absent from motor cortex. At the posterior end of the cortex, main target for visual info. Posterior pole of the occipital lobe is known as the primary visual cortex.
