The response to colour in the human visual cortex: the fMRI approach
Sign Up to like & getrecommendations! Published in 2019 at "Current Opinion in Behavioral Sciences"
DOI: 10.1016/j.cobeha.2019.08.001
Abstract: fMRI has been an important tool for understanding the functional organization of the human visual cortex for colour vision. Here I focus on three distinct approaches used in fMRI, each addressing a different question. Univariate… read more here.

GABA, noise and gain in human visual cortex
Sign Up to like & getrecommendations! Published in 2020 at "Neuroscience Letters"
DOI: 10.1016/j.neulet.2020.135294
Abstract: Highlights • Cortical GABA levels correlate with contrast detection thresholds.• GABA appears to reduce contrast response gain and intrinsic noise.• Changes in contrast discrimination can be characterised by the Wilson-Cowan model. read more here.

DOI: 10.1016/j.neuroimage.2019.116057
Abstract: Studies of changes in cerebral neocortical thickness often rely on small control samples for comparison with specific populations with abnormal visual systems. We present a normative dataset for FreeSurfer-derived cortical thickness across 25 human visual… read more here.

DOI: 10.1016/j.neuroimage.2019.116277
Abstract: Human visual perception is modulated by both temporal and spatial contexts. One type of modulation is apparent in the temporal context effect (TCE): In the presence of a constant luminance patch (a long flash), the… read more here.

DOI: 10.1016/j.neuroimage.2020.117153
Abstract: Hysteresis is a well-known phenomenon in physics that relates changes in a system with its prior history. It is also part of human visual experience (perceptual hysteresis), and two different neural mechanisms might explain it:… read more here.

DOI: 10.1038/s41598-020-59175-0
Abstract: Deep Convolutional Neural Networks (CNNs) are gaining traction as the benchmark model of visual object recognition, with performance now surpassing humans. While CNNs can accurately assign one image to potentially thousands of categories, network performance… read more here.

DOI: 10.1101/2022.01.04.474849
Abstract: The human visual ability to recognize objects and scenes is widely thought to rely on representations in category-selective regions of visual cortex. These representations could support object vision by specifically representing objects, or, more simply,… read more here.
