PSYCH 161 Lecture Notes - Lecture 1: Temporal Lobe, Entorhinal Cortex, Psych
Document Summary
Collections of interconnected areas which work together in processing information of a particular type. "large scale neural network" the highest level of functional organization, involving many different cortical systems including those in sensory, motor, and limbic cortex. A majority, but not all, of the connections are reciprocal. Processing proceeds in stages with each stage building on the. Sensory systems are located in posterior portions of the cerebral cortex computations carried out in the earlier stage. Encompasses portions of the occipital, temporal,& parietal lobes. Upstream areas on dorsal surface (temporal plane) Downstream areas spread in roughly concentric circles around the core. Four somatotopic maps in si, two responsive to skin, two responsive to deep receptors. Additional higher-level somato systems located in insula & ppc. Sii is inferior to si on anterior parietal operculum. Internal state systems are located in medial portions of the cerebral cortex. Medial temporal lobe important for ltm encoding.
