From: Lateral intraparietal area (LIP) is largely effector-specific in free-choice decisions
(A) Proportion of contralesional reach and saccade choices for monkey H across control and inactivation sessions. The error bars correspond to SD across sessions (13 control and 9 inactivation sessions). (B) Similar to A, but for monkey G (11 control and 4 inactivation sessions). LIP inactivation caused a reduction of contralesional saccade and reach choices in both animals. However, the effect was stronger when choices were made using eye rather than hand movements, as indicated by the interaction between the factors treatment and effector (mixed factorial ANOVA main effect on treatment for contralesional choices in monkey H: F(1,20) = 39.405, p = 4 × 10−6 and monkey G: F(1,13) = 27.277, p = 1.64 × 10−4, main effect on interaction in monkey H: F(1,20) = 4.487, p = 0.04 and in monkey G: F(1,13) = 5.511, p = 0.035). *p < 0.05, ***p < 0.0001 from a separate two-tailed t test analysis.
