Fig. 4
Effects of disrupting sensory flow of information to the DLS. a Schematic representation of the different phases of the Fron–Back–Front strategy expressed by the animals in the spatiotemporal task. Trajectories for every trial and average trajectory of a representative session are presented at the bottom. The different phases of the sequence are indicated in the average trajectory. b Schematic view of functional disconnections to remove forelimb somesthetic information from the DLS. Lesions are represented as dark areas in the corresponding structures. c, d, f Goal area entrance times (c), percentage of correct trials (b), and position stereotypy index (f) for the different experimental groups. Data are presented as median + 75th and 25th percentiles for the entire learning curve (left) or grouping early (middle) or late (right) sessions of training. Horizontal lines (left; two-way ANOVA, group × day of training and Bonferroni post hoc test); * and # represent significant differences vs. control and VPL–DLS groups, respectively (one-way ANOVA and Bonferroni post hoc test). e Representative position trajectories for one animal from each experimental group (median + 75th and 25th percentiles; color code as in (b))
