PSYB55H3 Chapter Notes - Chapter 2.19: Occipital Lobe, Visual Cortex, Parietal Lobe
Document Summary
Gyri are the protruding areas seen on the surface of the cortex; sulci, or fissures, are the enfolded regions of the cortex. Brodmann div"d the brain into distinct regions based on the underlying cytoarchitectonics. The lobes of the brain include the frontal, parietal, temporal, and occipital lobes. The frontal lobe is for planning, cognitive control, and execution of mvmnts. The parietal lobe receives sensory input about touch, pain, temperature, and limb position, and its inv"d in coding space and coordinating actions. The temporal lobe contains auditory, visual, and multimodal processing areas. The limbic lobe (not really a lobe) is inv"d in emotional processing, learning, and memory. Topography is the principle that the anatomical organization of the body is reflected in the cortical represen"s of the body, both in the sensory cortex and motor cortex. Association cortices are those regions of cortex outside the sensory specific and motor cortical regions. Association cortex receives + integrates input from multiple sensory modalities.
