Relative precision of top-down attentional modulations is lower in early visual cortex compared to mid-and high-level visual areas

S Park, JT Serences - Journal of Neurophysiology, 2022 - journals.physiology.org
Top-down spatial attention enhances cortical representations of behaviorally relevant visual
information and increases the precision of perceptual reports. However, little is known about …

Unifying model for three forms of contextual modulation including feedback input from higher visual areas

S Di Santo, M Dipoppa, A Keller, M Roth, M Scanziani… - bioRxiv, 2022 - biorxiv.org

[HTML][HTML] Increasing the spatial extent of attention strengthens surround suppression

M Kınıklıoğlu, H Boyaci - Vision Research, 2022 - Elsevier
Here we investigate how the extent of spatial attention affects center-surround interaction in
visual motion processing. To do so, we measured motion direction discrimination thresholds …

Dissociable neural mechanisms of selective visual information processing underlie the effects of attention on visual appearance and response bias

S Itthipuripat, P Wiwatphonthana, P Sawetsuttipan… - 2022 - researchsquare.com
It has been debated if attention can penetrate early perceptual representations to alter visual
appearance or it simply induces response biases. Here, we tested these alternative …
