Intracerebral dynamics of saccade generation in the human frontal eye field and supplementary eye field.
Recent functional imaging and electrical stimulation studies have localized in humans two frontal regions critical for the production of saccadic and anti-saccadic eye movements: the frontal and supplementary eye fields (FEF and SEF, respectively). We investigated the time course of their activations during the generation of pro- and anti-saccades from direct intracranial EEG recordings of thre...

متن کاملRole of supplementary eye field in saccade initiation: executive, not direct, control.
The goal of this study was to determine whether the activity of neurons in the supplementary eye field (SEF) is sufficient to control saccade initiation in macaque monkeys performing a saccade countermanding (stop signal) task. As previously observed, many neurons in the SEF increase the discharge rate before saccade initiation. However, when saccades are canceled in response to a stop signal, ...
متن کاملCombination of neuronal signals representing object-centered location and saccade direction in macaque supplementary eye field.
Neurons in the macaque supplementary eye field (SEF) fire at different rates in conjunction with planning saccades in different directions. They also exhibit object-centered spatial selectivity, firing at different rates when the target of the saccade is at the left or right end of a horizontal bar. To compare the rate of incidence of the two kinds of signal, and to determine how they combine, ...
متن کاملFrames of reference for saccadic command tested by saccade collision in the supplementary eye field.
In what frame of reference does the supplementary eye field (SEF) encode saccadic eye movements? In this study, the "saccade collision" test was used to determine whether a saccade electrically evoked in the monkey's SEF is programmed to reach an oculocentric goal or a nonoculocentric (e.g., head or body-centered) goal. If the eyes start moving just before or when an oculocentric goal is impose...
