Experimental protocol and swim path lengths. (a) The water maze protocol consisted of multiple acquisitions followed by goal reversals. The first 30s of the first trial after each reversal were considered as probe trials. The original experimental design also included a second period of behavioral testing (shaded), which was not subject of the analysis in the present study. (b–g) Path length to reach the hidden platform. Shown are means ± standard deviations. Control values are always connected by dashed lines.
