Hippocampal dynamics predict interindividual cognitive differences in rats.

Hippocampal dynamics predict interindividual cognitive differences in rats. Take-home message: Individual memory in old rats was assessed using DNMS. We recorded hippocampal CA1 place cells as these rats explored a familiar environment; 27% of recorded pyramidal neurons showed substantial delayed onsets of place field activity. This age-related firing onset delay occurred under basal conditions; it was… Read More
