PS365 Lecture 6: The Temporal Lobes
Document Summary
Temporal lobe anatomy: comprises all the tissue below the sylvian fissure and anterior to the occipital cortex, subcortical temporal lobe structures, limbic cortex. Lateral surface: brod(cid:373)a(cid:374)(cid:374)"s areas (cid:1008)(cid:1005), (cid:1008)(cid:1006), a(cid:374)d (cid:1006)(cid:1006, ventral stream of visual information. Inferotemporal cortex or te: brod(cid:373)a(cid:374)(cid:374)"s areas (cid:1006)(cid:1004), (cid:1006)(cid:1005), (cid:1007)(cid:1011), (cid:1006)(cid:1012, temporal sulci contain a lot of cortex. Surface anatomy: superior/middle/temporal gyrus, uncus (aka olfactory cortex), fusiform gyrus, inferior temporal gyrus. Inferotemporal cortex (area te) 20, 21, 37, 38. Internal structures of the temporal lobes: amygdala, hippocampus. Inferotemporal cortex to ventral striatum (nucleus accumbens) to process stimulus valence (attractive or aversive: medial temporal pathway long term memory, orbitofrontal pathway object-reward associations, ventrolateral prefrontal pathway object-working memory. Involves the hippocampus; contains cells that code for spatial location (space cells, code for location of where an animal is going to go and where it has been) Brain activity during natural vision: broad scenes parahippocampal place area (ppa, faces fusiform face area (ffa)
