Connectivity changes underlying neurofeedback training of visual cortex activity.

open access: yesPLoS 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.

Why do children with autism spectrum disorder have abnormal visual perception?

open access: yesFrontiers 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

Audiovisual temporal correspondence modulates human multisensory superior temporal sulcus plus primary sensory cortices [PDF]

open access: yes, 2007
The brain should integrate related but not unrelated information from different senses. Temporal patterning of inputs to different modalities may provide critical information about whether those inputs are related or not.

Multi-voxel decoding and the topography of maintained information during visual working memory

open access: yesFrontiers 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.

Paroxetine can improve primary visual cortex activity in a high-risk mouse model of schizophrenia

open access: yesBiotechnology & 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.

Flexible adjustment of the effective connectivity between the fronto-parietal and visual regions supports cognitive flexibility

open access: yesNeuroImage, 2020
Evidence indicates the significance of the fronto-parietal regions and inertia sensory processing from previous trials in cognitive flexibility. However, how flexible cognitive performance is achieved by causal interactions between cortical regions ...

The significance of memory in sensory cortex [PDF]

open access: yes, 2017
Early sensory cortex is typically investigated in response to sensory stimulation, masking the contribution of internal signals. Recently, van Kerkoerle and colleagues reported that attention and memory signals segregate from sensory signals within ...

Auditory attention activates peripheral visual cortex. [PDF]

open access: yesPLoS ONE, 2009
BackgroundRecent neuroimaging studies have revealed that putatively unimodal regions of visual cortex can be activated during auditory tasks in sighted as well as in blind subjects.
