Suppression of unwanted reflexive saccades is a crucial process allowing to sustain voluntary fixation, when required. This inhibition process, which is mainly controlled by the dorsolateral prefrontal cortex, may also involve other cortical and subcortical structures. We prospectively studied the effect of frontal cortical resections involving adjacent regions to the anterior cingulate cortex on the ability to inhibit reflexive saccades. This lesion study included six patients undergoing resection of frontal low grade gliomas, studied prior and after surgery with electro-oculography, using the antisaccade paradigm. Lesions were normalized and mapped in Talairach space allowing to detail the structures whose lesions were associated with antisaccade deficits.

 In three of the six patients significant early post-operative antisaccade errors were associated with resection of a common critical region, mainly involving the posterior part of the anterior cingulate cortex. This same region was spared in the three remaining patients with no antisaccade deficit, suggesting that the anterior cingulate cortex, known as the cingulate eye field, could play a role in suppression of unwanted saccades.
