A) Mean (+SEM) trials to reach criterion for Controls and DTN during cued platform training of Experiment 1. B–D) Representative paths from Control and DTN rats at Mid-Training (B), during the final training trial (C), and during the probe trial with the cue and platform removed from the pool (D). Swim paths were taken from animals with median values for path length (panels B–C) and initial heading error during the probe (panel D) within their respective group. E) Mean (+SEM) initial heading error for Controls and DTN during the probe trial of Experiment 1. Heading error (angular deviation from a straight trajectory to the platform) was measured when the animals has traveled path length equal to 25% of the pool diameter.
