(A) For L-Dopa-starters, the magnitude of grid-like activity in the right EC is significantly higher under Placebo than under L-Dopa. For Placebo-starters, grid-like activity does not differ significantly between L-Dopa and Placebo. Error bars show bootstrapped 95% confidence intervals. (B) Distance to location across interventions and sessions. For L-Dopa-starters, the distance to location is significantly lower under Placebo than under L-Dopa. For Placebo-starters, the distance to location is not significantly different between L-Dopa and Placebo. (C) Magnitude of contrasts for control models (5- and 7-fold symmetries) for L-Dopa-starters in both intervention sessions. (D) Same for L-Dopa-starters.
