Averaged latencies of young and old rats.

<p>(A) Averaged peak response latencies of neurons from fore- and hindpaw-representations of young (black) and aged (red) animals are shown. Error bars indicate the SEM. * p<0.01. (B) Normalized age-related lengthening of peak response latencies. The lengthening was 24.4% for the forepaw and 36.2% for the hindpaw. In contrast to the parameter RF-size the lengthening of latencies was similarly affected in cortical neurons of fore- and hindpaw-representation.
