Relationships between microstimulation effects on correct performance rates and reaction times for saccades toward the opposite directions in response to the same stimulus. A, Correlation between Δ correct performance rates on contralateral antisaccade trials and reaction times indices on ipsilateral prosaccade trials. B, Correct performance rates for contralateral prosaccades and reaction time indices for ipsilateral antisaccades. C, Correct performance rates for ipsilateral antisaccades and reaction time indices for contralateral prosaccades. D, Correct performance rates for ipsilateral prosaccades and reaction time indices for contralateral antisaccades. The number of data points in all panels is 179 (85 and 94 in monkeys O and E, respectively). Negative correlation between Δ correct performance rates and reaction time indices indicates that correct performance rates were worsened when microstimulation facilitated saccades toward the opposite direction. We confirmed the results using Spearman's correlation coefficients (data not shown). We also confirmed similar results when data from two monkeys were analyzed separately.
