The Visual Mismatch Negativity Elicited with Visual Speech Stimuli

Frontiers in Human Neuroscience, 2013
The visual mismatch negativity (vMMN), deriving from the brain’s response to stimulus deviance, is thought to be generated by the cortex that represents the stimulus. The vMMN response to visual speech stimuli was used in a study of the lateralization of

Assessing differential effects of single and accelerated low‐frequency rTMS to the visual cortex on GABA and glutamate concentrations

Brain and Behavior, 2020
Background The application of repetitive transcranial magnetic stimulation (rTMS) for therapeutic use in visual‐related disorders and its underlying mechanisms in the visual cortex is under‐investigated.

Surface-Based Analyses of Anatomical Properties of the Visual Cortex in Macular Degeneration.

PLoS ONE, 2016
IntroductionMacular degeneration (MD) can cause a central visual field defect. In a previous study, we found volumetric reductions along the entire visual pathways of MD patients, possibly indicating degeneration of inactive neuronal tissue.

Visual Deprivation Decreases Somatic GAD65 Puncta Number on Layer 2/3 Pyramidal Neurons in Mouse Visual Cortex

Neural Plasticity, 2009
Proper functioning of the visual system depends on maturation of both excitatory and inhibitory synapses within the visual cortex. Considering that perisomatic inhibition is one of the key factors that control the critical period in visual cortex, it is ...

Reward coding across mouse visual cortical areas

Frontiers in Behavioral Neuroscience
The visual cortex is an established site of reward-related signaling, but this evidence comes almost entirely from the primary visual cortex and from trained associative paradigms, leaving open whether and how a dedicated reward signal is organized ...

Classification of Real and Imagined Sounds in Early Visual Cortex

i-Perception, 2011
Early visual cortex has been thought to be mainly involved in the detection of low-level visual features. Here we show that complex natural sounds can be decoded from early visual cortex activity, in the absence of visual stimulation and both when sounds

Neural signature of chronic migraine mice model and related photophobia in the primary visual cortex

The Journal of Headache and Pain
Background Migraine episodes are known to induce heightened photosensitivity. Neuroimaging investigations have revealed that the primary visual cortex exhibits abnormal activation patterns both during and between migraine attacks.

Distinct gradients of cortical architecture capture visual representations and behavior across the lifespan

eLife
The microstructure of cells within the human cerebral cortex varies across the cortical ribbon, where changes in cytoarchitecture and myeloarchitecture are thought to endow each region of the cortex with its unique function.

Investigating the Effect of Space Frequency Modulation of Visual Stimuli on the Visual Acuity of the Optic Cortex

Majallah-i Dānishgāh-i ̒Ulūm-i Pizishkī-i Bābul, 2017
BACKGROUND AND OBJECTIVE: The choice of the response of the visual cortex to different space frequencies has been studied in several studies. The importance of the present study is to investigate the role of space frequency modulation in determining the ...
