Document Summary
External cue: mtl takes cue and completes the pattern at retrival. Hippocampus well-suited for formation, storage and retrieval of memories! b/c it represents a closed circuit. Info keeps flowing, processed, elaborated on over and over. Intricate sub-connections w/in hippocampus to allow memories to be re-activated at retrieval. H. m had damage to hippocampus, it is very well suited for formation of memories because represents a closed circuit, allows for memories to be processed over and over. Entorhinal cortex receives information from other parts of brain i. e. parahippocampal and perirhinal cortices. Suggests we should think about memory in terms of processes. Need to know that hippocampus is closed circuit as well as the diff bw dendrate gyrus ca3 subfield. Dentate gyrus: narrow, concave, wraps around ca4 subfield. Entorhinal neurons (major input to hippocampus) dendate gyrus ca3 ca1 subiculum and back around = entorhinal cortex *perferant pathways==closed circuit. Schaeffer collaterals: auto-associative, allows for info to reverberate w/in the ca3 sub-fields pattern completion.
