    • A Refined Neuronal Population Measure of Visual Attention. 

      Mayo, Patrick; Cohen, Marlene R; Maunsell, John HR (PloS one, 2015-01)
      Neurophysiological studies of cognitive mechanisms such as visual attention typically ignore trial-by-trial variability and instead report mean differences averaged across many trials. Advances in electrophysiology allow ...
    • Advances in color science: from retina to behavior. 

      Johnson, Elizabeth; Field, Greg; Conway, Bevil R; Chatterjee, Soumya; Horwitz, Gregory D; Koida, Kowa; Mancuso, Katherine (The Journal of neuroscience : the official journal of the Society for Neuroscience, 2010-11)
      Color has become a premier model system for understanding how information is processed by neural circuits, and for investigating the relationships among genes, neural circuits, and perception. Both the physical stimulus ...
    • Changes in Brain Resting-state Functional Connectivity Associated with Peripheral Nerve Block: A Pilot Study. 

      Browndyke, Jeffrey Nicholas; Harshbarger, Todd Brenson; Klein, SM; Madden, David Joseph; Melton, MS; Nielsen, Karen C (Anesthesiology, 2016-08)
      BACKGROUND: Limited information exists on the effects of temporary functional deafferentation (TFD) on brain activity after peripheral nerve block (PNB) in healthy humans. Increasingly, resting-state functional connectivity ...
    • Configural specificity of the lateral occipital cortex. 

      Ales, JM; Appelbaum, Lawrence Gregory; Cottereau, Benoit R; Norcia, AM (Neuropsychologia, 2010-09)
      While regions of the lateral occipital cortex (LOC) are known to be selective for objects relative to feature-matched controls, it is not known what set of cues or configurations are used to promote this selectivity. Many ...
    • 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 ...
    • Feature-specific clusters of neurons and decision-related neuronal activity. 

      Mayo, Patrick; Verhoef, Bram-Ernst (The Journal of neuroscience : the official journal of the Society for Neuroscience, 2014-06)
    • Graded Neuronal Modulations Related to Visual Spatial Attention. 

      Mayo, Patrick; Maunsell, John HR (The Journal of neuroscience : the official journal of the Society for Neuroscience, 2016-05)
      UNLABELLED:Studies of visual attention in monkeys typically measure neuronal activity when the stimulus event to be detected occurs at a cued location versus when it occurs at an uncued location. But this approach does not ...
    • Imagery and retrieval of auditory and visual information: neural correlates of successful and unsuccessful performance. 

      Daselaar, SM; Huijbers, W; Pennartz, CM; Rubin, David C (Neuropsychologia, 2011-06)
      Remembering past events - or episodic retrieval - consists of several components. There is evidence that mental imagery plays an important role in retrieval and that the brain regions supporting imagery overlap with those ...
    • Neuronal Adaptation: Tired Neurons or Wired Networks? 

      Mayo, Patrick; Smith, Matthew A (Trends in neurosciences, 2017-03)
      Neuronal adaptation - time-dependent modulation of sensory responses following sequential stimuli - is thought to be a consequence of synaptic plasticity. But recent, empirically-grounded, modeling by Quiroga and colleagues ...
    • Spatial and temporal scales of neuronal correlation in visual area V4. 

      Smith, MA; Sommer, Marc A (J Neurosci, 2013-03-20)
      The spiking activity of nearby cortical neurons is correlated on both short and long time scales. Understanding this shared variability in firing patterns is critical for appreciating the representation of sensory stimuli ...
    • The time course of segmentation and cue-selectivity in the human visual cortex. 

      Appelbaum, Lawrence Gregory; Ales, JM; Norcia, AM (PLoS One, 2012)
      Texture discontinuities are a fundamental cue by which the visual system segments objects from their background. The neural mechanisms supporting texture-based segmentation are therefore critical to visual perception and ...
    • The time course of shape discrimination in the human brain. 

      Ales, JM; Appelbaum, Lawrence Gregory; Cottereau, Benoit R; Norcia, AM (Neuroimage, 2013-02-15)
      The lateral occipital cortex (LOC) activates selectively to images of intact objects versus scrambled controls, is selective for the figure-ground relationship of a scene, and exhibits at least some degree of invariance ...
