PS267 Chapter Notes - Chapter 9: Posterior Parietal Cortex, Temporal Lobe, Parahippocampal Gyrus
Document Summary
Encoding and the hippocampus: measures of brain activity during encoding show correctly recollected words activated both the hippocampus and posterior para-hippocampal cortex (see if there is difference in coding for words remembered vs not remembered) Found hippocampus also activated during retrieval, specifically for episodic memories. Perirhinal cortex: represents info about specific items (what and who) Para-hippocampal cortex: represents info about context (what and when) Modality-specific regions of activity in the neocortex during memory retrieval matched areas activated by the perceptual info alone. Had people look at pictures and measured brain activity , measured brain activity in retrieval of the memory of the picture and area of activation overlapped. Encoding, retrieval, and frontal cortex: meta-analysis found frontal cortex is often activated during episodic memory retrieval. Episodic memory (when and where tag): front left area. Everything semantic: left frontal area: material-specific frontal cortex activation during memory encoding. Linguistic encoding in the left frontal cortex, spatial/object encoding in the right frontal cortex.
