Hierarchical and homotopic correlations of spontaneous neural activity within the visual cortex of the sighted and blind

open access: yesFrontiers in Human Neuroscience, 2015
Spontaneous neural activity within visual cortex is synchronized by both monosynaptic, hierarchical connections between visual areas and indirect, network-level activity.

Physiological Mechanisms Underlying Motion-Induced Blindness [PDF]

open access: yes, 2008
Visual disappearance illusions - such as motion-induced blindness (MIB) - are commonly used to study the neural underpinnings of visual perception. In such illusions a salient visual target becomes perceptually invisible.

Anodal transcranial direct current stimulation does not alter GABA concentration or functional connectivity in the normal visual cortex

open access: yesFrontiers in Neuroscience
IntroductionAnodal direct current stimulation (a-tDCS) of the visual cortex is a potential rehabilitation tool for vision disorders such as amblyopia and macular degeneration. However, the underlying neural mechanisms are currently unknown.

Experience-Dependent Development and Maintenance of Binocular Neurons in the Mouse Visual Cortex

open access: yesCell Reports, 2020
Summary: The development of neuronal circuits requires both hard-wired gene expression and experience-dependent plasticity. Sensory processing, such as binocular vision, is especially sensitive to perturbations of experience.

Evidence that primary visual cortex is required for image, orientation, and motion discrimination by rats. [PDF]

open access: yesPLoS ONE, 2013
The pigmented Long-Evans rat has proven to be an excellent subject for studying visually guided behavior including quantitative visual psychophysics. This observation, together with its experimental accessibility and its close homology to the mouse, has ...

Increased motor cortex excitability for concealed visual information [PDF]

open access: yes, 2019
Deceptive behaviour involves complex neural processes involving the primary motor cortex. The dynamics of this motor cortex excitability prior to lying are still not well understood.

Multisensory and Modality Specific Processing of Visual Speech in Different Regions of the Premotor Cortex

open access: yesFrontiers in Psychology, 2014
Behavioral and neuroimaging studies have demonstrated that brain regions involved with speech production also support speech perception, especially under degraded conditions.

Attentional preparation for a lateralized visual distractor: Behavioral and fMRI evidence [PDF]

open access: yes, 2006
Attending to the location of all expected visual target call lead to anticipatory activations In spatiotopic occipital cortex, emerging before target onset.

Category-specific responses to faces and objects in primate auditory cortex

open access: yesFrontiers in Systems Neuroscience, 2008
Auditory and visual signals often occur together, and the two sensory channels are known to infl uence each other to facilitate perception. The neural basis of this integration is not well understood, although other forms of multisensory infl uences have

Tactile spatial attention enhances gamma-band activity in somatosensory cortex and reduces low-frequency activity in parieto-occipital areas. [PDF]

open access: yes, 2006
We investigated the effects of spatial-selective attention on oscillatory neuronal dynamics in a tactile delayed-match-to-sample task. Whole-head magnetoencephalography was recorded in healthy subjects while dot patterns were presented to their index ...
