LCGU values (mean ± SD in μmol/100 g/min) in temporal cortical areas for observation of reaching-to-grasp movements. Oi (Oc) values represent the average LCGU values from the three hemispheres of the O monkeys ipsilateral (contralateral) to the perceived forelimb. Oi/Cf% (Oc/Cf%), percentage differences between the Oi (Oc) and the Cf, calculated as [experimental (ipsilateral or contralateral) − control]/control × 100. Oi/Cmi% (Oc/Cmc%), percentage differences between the Oi (Oc) and the Cmi (Cmc), respectively. Boldface values indicate statistically significant differences by one-way ANOVA (p < 0.01) followed by Dunnett's post hoc test. Abbreviations are as defined in Table 3.
