Explain what is meant by a place cell and discuss the role of these cells in spatial memory
What will be an ideal response?
Answer: The ability to navigate requires an intact hippocampus. H.M. had difficulties in spatial navigation. The firing rate of individual hippocampal cells was a function of the spatial location of the rat as it wandered around a maze. The external cues of the environment can control the firing rate of hippocampal cells, particularly of cells in the dorsal hippocampus (a key region for spatial navigation). The entorhinal cortex, which is an important input zone for the hippocampus, is also important for spatial navigation.
