Lipid pathway alterations in Parkinson's disease primary visual cortex. [PDF]
PLoS ONE, 2011 BackgroundWe present a lipidomics analysis of human Parkinson's disease tissues. We have focused on the primary visual cortex, a region that is devoid of pathological changes and Lewy bodies; and two additional regions, the amygdala and anterior ...

Why do children with autism spectrum disorder have abnormal visual perception?
Frontiers in Psychiatry, 2023 Autism spectrum disorder (ASD) is associated with severe impairment in social functioning. Visual information processing provides nonverbal cues that support social interactions. ASD children exhibit abnormalities in visual orientation, continuous visual

fMRI of Monkey Visual Cortex [PDF]
Neuron, 1998 While functional magnetic resonance imaging (fMRI) is now used widely for demonstrating neural activity-related signals associated with perceptual, motor, and cognitive processes in humans, to date this technique has not been developed for use with nonhuman primates.

Connectivity changes underlying neurofeedback training of visual cortex activity.
PLoS ONE, 2014 Neurofeedback based on real-time functional magnetic resonance imaging (fMRI) is a new approach that allows training of voluntary control over regionally specific brain activity.

Multi-voxel decoding and the topography of maintained information during visual working memory
Frontiers in Systems Neuroscience, 2016 The ability to maintain representations in the absence of external sensory stimulation, such as in working memory, is critical for guiding human behavior.

Sensitivity to syntax in visual cortex [PDF]
Cognition, 2009 One of the most intriguing findings on language comprehension is that violations of syntactic predictions can affect event-related potentials as early as 120 ms, in the same time-window as early sensory processing. This effect, the so-called early left-anterior negativity (ELAN), has been argued to reflect word category access and initial syntactic ...

Paroxetine can improve primary visual cortex activity in a high-risk mouse model of schizophrenia
Biotechnology & Biotechnological Equipment, 2020 Visual cortex functional deficits can be observed in schizophrenia patients and in individuals at high risk of schizophrenia. However, to date, few studies have investigated methods to improve these functional deficits.

Attention: Control in the Visual Cortex [PDF]
Current Biology, 2007 A recent study in which the human visual cortex was directly stimulated to create visual percepts has shown that visual spatial attention can act directly on neural activity in sensory cortex without involving attentional modulation of subcortical visual inputs.

Contextual modulation of primary visual cortex by auditory signals [PDF]
, 2017 Early visual cortex receives non-feedforward input from lateral and top-down connections (Muckli & Petro 2013 Curr. Opin. Neurobiol. 23, 195–201. (doi:10.1016/j.conb.2013.01.020)), including long-range projections from auditory areas.
