PSY397H5 Lecture Notes - Lecture 5: Anterograde Amnesia, Theta Wave, Auditory Cortex
Document Summary
Anterograde amnesia is induced if removal of hippocampus. The brain can recover from stroke, but hippocampus is not replaceable. Electronic amplification techniques to measure single neuronal function. First sign of alzheimer"s disease is that spatial computation is adversely affected, as the function of hippocampus is compromised. If hippocampus is missing, salient cues, temporal (what day of the week is it?) features will be recognizable but the nuances cannot be distinguished or recognized. The cortex stores all the pieces of the information, just like books are stored in the library containing individual information. Isolated from the brain by white matter, enclosed in glial cells and is involved in outputting info and inputing info. Hippocampus is still alive, if the animal is not dead for too long and can be studied. Piece of grey tissue stay alive for weeks inside the hippocampus (grey lines) and are studied. Tri synaptic circuit dg ca3 ca1.
