Scatter Plot from Scientific Research

Comparison of PSE with (ordinate) and without (abscissa) microstimulation during the stimulus-presentation period. Black arrows mark the median PSE. Marginal histogram counts the frequency of ∆PSE, with the median value indicated by a perpendicular solid line. Solid bars and dots indicate significant shifts; open bars and dots are insignificant changes. All p values are from a two-tailed Wilcoxon signed-rank test; significance level, 0.01. Dots above or below the dashed diagonal, respectively, represent that animal choices are biased toward ipsilateral or contralateral side compared to the manipulated hemisphere.
