Document Summary
Cognition: the ability to attend to external stimuli or internal motivation, to identify the significance of the stimuli and to make appropriate responses. Most of the surface of the human brain is devoted to cognition except for the primary sensory and. The association cortices of the parietal, temporal and frontal lobes are involved in the integrative motor areas processing that underlies cognition. Association cortices receive and integrate information from a variety of sources and influence many cortical and sub-cortical regions: one of the major sources of cortical input is other cortical areas, other sources and targets are: Neocortex in humans is made of 6 laminae (layers) Layers are separated based on distinctive cells, density, input and outputs. Variations in cortex composition allows us to divide the brain into neuroanatomical regions. Interneurons within specific layers have extensive horizontal axons that link groups of cells with a similar function. 2 thalamic nuclei provide subcortical input to association cortices: pulvinar, medial dorsal nuclei.
