Bottom-up retinotopic organization supports top-down mental imagery [PDF]

open access: yes, 2013
Finding a path between locations is a routine task in daily life. Mental navigation is often used to plan a route to a destination that is not visible from the current location. We first used functional magnetic resonance imaging (fMRI) and surface-based

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.

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.

Contextual modulation of primary visual cortex by auditory signals [PDF]

open access: yes, 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.

Cortical Dynamics of Contextually-Cued Attentive Visual Learning and Search: Spatial and Object Evidence Accumulation [PDF]

open access: yes, 2009
How do humans use predictive contextual information to facilitate visual search? How are consistently paired scenic objects and positions learned and used to more efficiently guide search in familiar scenes?

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.

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.

Integrating visual and tactile information in the perirhinal cortex [PDF]

open access: yes, 2009
By virtue of its widespread afferent projections, perirhinal cortex is thought to bind polymodal information into abstract object-level representations.

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 ...

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.
