Effects of pharmacological inactivation of theVPL. a Schematic representation of the VPL inactivation procedure. b Goal area entrance times for four sessions before and after (black) the administration of muscimol in the VPL (green, 50 ng in 0.5 μl). The different phases of the sequence are indicated in the average trajectory. c Group effect for muscimol injections on entrance times (c) and percentage of correct trials (d) (median + 75th and 25th percentiles). Representative position (e) and speed (g) trajectories and group effects on position (f) and speed (h) before and after (black) muscimol (green). *P < 0.01, **P < 0.001, Kruskall–Wallis and Tukey’s HSD test (c, d, f, h)
