    Frontal eye field sends delay activity related to movement, memory, and vision to the superior colliculus. 

    Sommer, Marc A; Wurtz, RH (J Neurophysiol, 2001-04)
    Many neurons within prefrontal cortex exhibit a tonic discharge between visual stimulation and motor response. This delay activity may contribute to movement, memory, and vision. We studied delay activity sent from the frontal ...

    Division of labor in frontal eye field neurons during presaccadic remapping of visual receptive fields. 

    Shin, S; Sommer, Marc A (J Neurophysiol, 2012-10)
    Our percept of visual stability across saccadic eye movements may be mediated by presaccadic remapping. Just before a saccade, neurons that remap become visually responsive at a future field (FF), which anticipates the saccade ...

    Express saccades elicited during visual scan in the monkey. 

    Sommer, Marc A (Vision Res, 1994-08)
    Monkeys trained to saccade to visual targets can develop separate "express" and "regular" modes in their distribution of saccadic latencies. The purpose of this study was to determine whether this occurs under more natural ...

    Neuronal correlates of metacognition in primate frontal cortex. 

    Middlebrooks, PG; Sommer, Marc A (Neuron, 2012-08-09)
    Humans are metacognitive: they monitor and control their cognition. Our hypothesis was that neuronal correlates of metacognition reside in the same brain areas responsible for cognition, including frontal cortex. Recent ...

    Electrically evoked saccades from the dorsomedial frontal cortex and frontal eye fields: a parametric evaluation reveals differences between areas. 

    Sommer, Marc A; Tehovnik, EJ (Exp Brain Res, 1997-12)
    Using electrical stimulation to evoke saccades from the dorsomedial frontal cortex (DMFC) and frontal eye fields (FEF) of rhesus monkeys, parametric tests were conducted to compare the excitability properties of these regions. ...

    Neuronal adaptation caused by sequential visual stimulation in the frontal eye field. 

    Mayo, J Patrick; Sommer, Marc A (J Neurophysiol, 2008-10)
    Images on the retina can change drastically in only a few milliseconds. A robust description of visual temporal processing is therefore necessary to understand visual analysis in the real world. To this end, we studied subsecond ...

    Dynamics of visual receptive fields in the macaque frontal eye field. 

    DiTomasso, AR; Mayo, J Patrick; Smith, MA; Sommer, Marc A (J Neurophysiol, 2015-12)
    Neuronal receptive fields (RFs) provide the foundation for understanding systems-level sensory processing. In early visual areas, investigators have mapped RFs in detail using stochastic stimuli and sophisticated analytical ...

    What the brain stem tells the frontal cortex. I. Oculomotor signals sent from superior colliculus to frontal eye field via mediodorsal thalamus. 

    Sommer, Marc A; Wurtz, RH (J Neurophysiol, 2004-03)
    Neuronal processing in cerebral cortex and signal transmission from cortex to brain stem have been studied extensively, but little is known about the numerous feedback pathways that ascend from brain stem to cortex. In this ...

    Express averaging saccades in monkeys. 

    Chou, IH; Schiller, PH; Sommer, Marc A (Vision Res, 1999)
    When monkeys are presented simultaneously with multiple stimuli, they can make one of two types of response. Either they make averaging saccades, that land at intermediate locations between the targets, or target-directed ...

    What the brain stem tells the frontal cortex. II. Role of the SC-MD-FEF pathway in corollary discharge. 

    Sommer, Marc A; Wurtz, RH (J Neurophysiol, 2004-03)
    One way we keep track of our movements is by monitoring corollary discharges or internal copies of movement commands. This study tested a hypothesis that the pathway from superior colliculus (SC) to mediodorsal thalamus ...
