Neurons of the hippocampus form and function
... We compared the real-time activity of living cells in the three different regions (GC, CA3, CA1) of the hippocampus by using electrophysiology. The frequency of excitatory activity varies among granule and pyramidal cells. Granule cells tend to be more excitable. Confocal microscopy was then used to ...
