    • Beyond the labeled line: variation in visual reference frames from intraparietal cortex to frontal eye fields and the superior colliculus 

      Caruso, Valeria; Pages, D; Sommer, Marc A.; Groh, Jennifer M. (Journal of Neurophysiology, 2017-12-20)
      We accurately perceive the visual scene despite moving our eyes ~3 times per second, an ability that requires incorporation of eye position and retinal information. In this study, we assessed how this neural computation ...
    • Circuits for presaccadic visual remapping. 

      Rao, Hrishikesh; Mayo, J. Patrick; Sommer, Marc A. (J Neurophysiol, 2016-12-01)
      Saccadic eye movements rapidly displace the image of the world that is projected onto the retinas. In anticipation of each saccade, many neurons in the visual system shift their receptive fields. This presaccadic change ...
    • Evaluating the effects of image persistence on dynamic target acquisition in low frame rate virtual environments 

      Zielinski, David; Rao, Hrishikesh; Potter, Nicholas; Sommer, Marc A.; Appelbaum, Lawrence Gregory; KOPPER, REGIS (IEEE 3D User Interfaces (3DUI), 2016-03-19)
      User performance in virtual environments with degraded visual conditions due to low frame rates is an interesting area of inquiry. Visual content shown in a low frame rate simulation has the quality of the original image, ...
    • Neural network evidence for the coupling of presaccadic visual remapping to predictive eye position updating 

      Rao, Hrishikesh; San Juan, J; Shen, F; Villa, J; Rafie, K; Sommer, Marc A. (Frontiers in Computational Neuroscience, 2016-05-18)
      As we look around a scene, we perceive it as continuous and stable even though each saccadic eye movement changes the visual input to the retinas. How the brain achieves this perceptual stabilization is unknown, but a major ...
    • Probabilistic inference under time pressure leads to a cortical-to-subcortical shift in decision evidence integration 

      Oh-Descher, H; Beck, JM; Ferrari, Silvia; Sommer, Marc A.; Egner, Tobias (NeuroImage, 2017-08-24)
      Real-life decision-making often involves combining multiple probabilistic sources of information under finite time and cognitive resources. To mitigate these pressures, people “satisfice”, foregoing a full evaluation of ...

    • Sensorimotor learning during a marksmanship task in immersive virtual reality 

      Sommer, Marc; Appelbaum, Lawrence; Rao, Hrishikesh; Khanna, Rajan; Zielinski, David; Lu, Yvonne; Clements, Jillian; Potter, Nicholas; Kopper, Regis (Frontiers in Psychology, 2018-02-06)
      Sensorimotor learning refers to improvements that occur through practice in the performance of sensory-guided motor behaviors. Leveraging novel technical capabilities of an immersive virtual environment, we probed the ...
    • Serial decision-making in monkeys during an oculomotor task 

      Abzug, ZM; Sommer, Marc A. (Journal of Experimental Psychology: Animal Learning and Cognition, 2017-08-29)
      Much of everyday behavior involves serial decision-making, in which the outcome of one choice affects another. An example is setting rules for oneself: choosing a behavioral rule guides appropriate choices in the future. ...

    • Similar prevalence and magnitude of auditory-evoked and visually-evoked activity in the frontal eye fields: Implications for multisensory motor control 

      Caruso, Valeria; Pages, Daniel; Sommer, Marc A.; Groh, Jennifer M. (Journal of Neurophysiology, 2016)
      Saccadic eye movements can be elicited by more than one type of sensory stimulus. This implies substantial transformations of signals originating in different sense organs as they reach a common motor output pathway. In ...
    • Supplementary Eye Fields 

      Abzug, ZM; Sommer, Marc A. (Reference Module on Neuroscience and Biobehavioral Psychology, 2016-06-06)
      The supplementary eye fields (SEFs) are located in dorsomedial frontal cortex and contribute to high-level control of eye movements. Recordings in the SEF reveal neural activity related to vision, saccades, and fixations, ...

    • Visual continuity across saccades is Influenced by expectations 

      Rao, Hrishikesh; Abzug, Zack; Sommer, Marc A. (Journal of Vision, 2016-02-09)
      As we make saccades, the image on each retina is displaced, yet our visual perception is uninterrupted. This is commonly referred to as transsaccadic perceptual stability, but such a description is inadequate. Some visual ...
