Description
The function of the frontal eye fields was first discovered through electrical stimulation, when David Ferrier showed he could evoke saccadic eye movements in monkeys by applying an electrical current. In humans, electrical stimulation of the brain can be achieved with transcranial direct current stimulation (tDCS). tDCS cannot induce sufficient activity to directly evoke saccades, but it can influence the excitability of neurons. By modulating baseline activity in the frontal eye field, tDCS can potentially probe its role in saccade execution, but also in related functions, like shifting spatial attention. One study has systematically explored the effects of frontal eye field tDCS on eye movements (Kanai et al., 2012, Front. Pscyhiatry). They showed that anodal tDCS of the frontal eye field can decrease the median latency of saccades, specifically when saccades were made to targets in the visual hemifield contralateral to the …
