A neural model of contour integration in the primary visual cortex [PDF]
, 1998 Experimental observations suggest that contour integration may take place in V1. However, there has yet to be a model of contour integration that uses only known V1 elements, operations, and connection patterns.

FEBS Open Bio, EarlyView.The cytoskeleton‐mediated transport of mitochondria via tunnelling nanotubes restores respiration, increases ATP production, rescues cells from apoptosis, activates the AKT/mTOR signalling pathway, promotes cell migration and invasiveness, contributes to cancer progression and treatment resistance.

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).

Uncomfortable images produce non-sparse responses in a model of primary visual cortex [PDF]
, 2015 The processing of visual information by the nervous system requires significant metabolic resources. To minimize the energy needed, our visual system appears to be optimized to encode typical natural images as efficiently as possible.

FEBS Open Bio, EarlyView.Glioblastoma cells express calcitonin receptor variants (CT receptor isoforms) that may help them survive stress. Using qPCR, transcript‐specific long‐read nanopore sequencing, immunofluorescence co‐localisation and comparative sequence analysis, this study identifies a novel alternatively spliced CALCR transcript that encodes the CTb receptor isoform ...

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.

Posterior Cortical Atrophy in the Asia‐Pacific: A Report From the PCA Asian Workgroup
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Posterior Cortical Atrophy (PCA) is a distinct dementia syndrome primarily affecting spatial abilities and visual processing. It is associated with degeneration in the posterior part of the brain. PCA is subclassified into PCA‐pure and PCA‐plus syndromes based on consensus criteria.

The development of visual areas depends differently on visual experience. [PDF]
PLoS ONE, 2013 Visual experience plays an important role in the development of the visual cortex; however, recent functional imaging studies have shown that the functional organization is preserved in several higher-tier visual areas in congenitally blind subjects ...

Motion Opponency in Visual Cortex [PDF]
The Journal of Neuroscience, 1999 Perceptual studies suggest that visual motion perception is mediated by opponent mechanisms that correspond to mutually suppressive populations of neurons sensitive to motions in opposite directions. We tested for a neuronal correlate of motion opponency using functional magnetic resonance imaging (fMRI) to measure brain activity in human visual cortex.
