Visual mode switching learned through repeated adaptation to color

Autor: Yanjun Li, Katherine EM Tregillus, Qiongsha Luo, Stephen A Engel

Publikováno v: eLife, Vol 9 (2020)

When the environment changes, vision adapts to maintain accurate perception. For repeatedly encountered environments, learning to adjust more rapidly would be beneficial, but past work remains inconclusive. We tested if the visual system can learn su

Control of visual adaptation depends upon task.

Autor: Mark Vergeer, Stephen A Engel

Publikováno v: PLoS ONE, Vol 15, Iss 2, p e0229343 (2020)

The visual system optimizes its functioning for a given environment through processes collectively called adaptation. It is currently unknown, however, whether adaptation is affected by the particular task the observer performs within that environmen

Evidence for intact stimulus-specific neural adaptation for visual objects in schizophrenia and bipolar disorder: An ERP study.

Autor: Jonathan K Wynn, Stephen A Engel, Junghee Lee, Eric A Reavis, Michael F Green

Publikováno v: PLoS ONE, Vol 14, Iss 8, p e0221409 (2019)

People with schizophrenia (SZ) or bipolar disorder (BD) experience dysfunction in visual processing. Dysfunctional neural tuning, in which neurons and neuronal populations are selectively activated by specific features of visual stimuli, may contribu

Sustained Cortical and Subcortical Measures of Auditory and Visual Plasticity following Short-Term Perceptual Learning.

Autor: Bonnie K Lau, Dorea R Ruggles, Sucharit Katyal, Stephen A Engel, Andrew J Oxenham

Publikováno v: PLoS ONE, Vol 12, Iss 1, p e0168858 (2017)

Short-term training can lead to improvements in behavioral discrimination of auditory and visual stimuli, as well as enhanced EEG responses to those stimuli. In the auditory domain, fluency with tonal languages and musical training has been associate

Abnormal Ventral and Dorsal Attention Network Activity During Single and Dual Target Detection in Schizophrenia

Autor: Amy M. Jimenez, Junghee eLee, Jonathan K Wynn, Mark S. Cohen, Stephen A Engel, David C. Glahn, Keith H. Nuechterlein, Eric A. Reavis, Michael F. Green

Publikováno v: Frontiers in Psychology, Vol 7 (2016)

Early visual perception and attention are impaired in schizophrenia, and these deficits can be observed on target detection tasks. These tasks activate distinct ventral and dorsal brain networks which support stimulus-driven and goal-directed attenti

Larger Neural Responses Produce BOLD Signals That Begin Earlier in Time

Autor: Serena eThompson, Stephen A Engel, Cheryl eOlman

Publikováno v: Frontiers in Neuroscience, Vol 8 (2014)

Functional MRI analyses commonly rely on the assumption that the temporal dynamics of hemodynamic response functions (HRFs) are independent of the amplitude of the neural signals that give rise to them. The validity of this assumption is particularly

Confidence intervals for fMRI activation maps.

Autor: Stephen A Engel, Philip C Burton

Publikováno v: PLoS ONE, Vol 8, Iss 12, p e82419 (2013)

Neuroimaging activation maps typically color voxels to indicate whether the blood oxygen level-dependent (BOLD) signals measured among two or more experimental conditions differ significantly at that location. This data presentation, however, omits i

Slowed alpha oscillations and percept formation in psychotic psychopathology

Autor: Scott R. Sponheim, Joshua J. Stim, Stephen A. Engel, Victor J. Pokorny

Publikováno v: Frontiers in Psychology, Vol 14 (2023)

IntroductionPsychosis is in part defined by disturbances in perception. Recent investigations have implicated the speed of alpha oscillations observed in brain electrical activity as reflective of a sampling rate of the visual environment and percept
