Fig. 11.

Shows the frequency histograms of the spontaneous unit activity from a neuron in the CA 1 area of the hippocampus. Histogram A corresponds to the registration of a neuron in the control group, while histogram B corresponds to a neuron in the group with treatment both at 3 months of the study. Histogram C is a neuron of the control group and D is a histogram of a neuron of the group treated both at 6 months. In both periods a decrease in the firing frequency is shown in the neurons of animals with treatment with respect to the control.
