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.

Retinotopic activation in response to subjective contours in primary visual cortex. [PDF]
, 2008 Objects in our visual environment are arranged in depth and hence there is a considerable amount of overlap and occlusion in the image they generate on the retina.

Auditory attention activates peripheral visual cortex. [PDF]
PLoS 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.

Visual perception: Spotlight on the primary visual cortex [PDF]
Current Biology, 1999 Visual search tasks appear to involve spatially selective attention to the target, but evidence for attentional modulation in the visual area with the most precise retinotopic organization V1 has been elusive. Recent imaging studies show that spatial attention can indeed enhance visual responses in human V1.

A survey of architecture and function of the primary visual cortex (V1) [PDF]
, 2006 The largest visual area, known as the primary visual cortex or V1, has greatly contributed to the current understanding of mammalian and human visual pathways and their role in visual perception.

High-level visual prediction errors in early visual cortex.
PLoS BiologyPerception is shaped by both incoming sensory input and expectations derived from our prior knowledge. Numerous studies have shown stronger neural activity for surprising inputs, suggestive of predictive processing.

Hebbian synapses in visual cortex [PDF]
The Journal of Neuroscience, 1994 We discovered in slices of rat visual cortex that reliable long-term potentiation (LTP) of synaptic responses in layer III could be elicited by theta burst stimulation delivered to a site in the middle of the cortical thickness, corresponding mainly to layer IV.

The human visual system differentially represents subjectively and objectively invisible stimuli.
PLoS Biology, 2021 The study of unconscious processing requires a measure of conscious awareness. Awareness measures can be either subjective (based on participant's report) or objective (based on perceptual performance).
