متن کاملContrasting the roles of the supplementary and frontal eye fields in ocular decision making.
Single-unit recording in monkeys and functional imaging of the human frontal lobe indicate that the supplementary eye field (SEF) and the frontal eye field (FEF) are involved in ocular decision making. To test whether these structures have distinct roles in decision making, single-neuron activity was recorded from each structure while monkeys executed an ocular go/nogo task. The task rule is to...
متن کاملSupplementary eye field activity reflects a decision rule governing smooth pursuit but not the decision.
Animals depend on learned rules to guide their actions. Prefrontal (PFC) and premotor (PMC) cortex of primates have been reported to display rule-related neural activity, but it is unclear how signals encoded here are utilized to enforce the decision to act. The supplementary eye field (SEF) is a candidate for enforcing rule-guided ocular decisions because the activity of neurons here is correl...
متن کاملFlexible interpretation of a decision rule by supplementary eye field neurons.
Since the environment is in constant flux, decision-making capabilities of the brain must be rapid and flexible. Yet in sensory motion processing pathways of the primate brain where decision making has been extensively studied, the flexibility of neurons is limited by inherent selectivity to motion direction and speed. The supplementary eye field (SEF), an area involved in decision making on mo...
متن کاملThe effects of microstimulation of the dorsomedial frontal cortex on saccade latency.
Neural regions in the dorsomedial frontal cortex (DMFC), including the supplementary eye field (SEF) and the presupplementary motor area (pre-SMA), are likely candidates for generating top-down control of saccade target selection. To investigate this, we applied electrical microstimulation to these structures while saccades were being planned to visual targets. Stimulation administered to super...
