Haptic shape processing in visual cortex. by Snow, J, Strother, L, Humphreys, G

“…The shape-specific repetition effects we observed in primary visual cortex show that visual sensory areas are engaged during the haptic exploration of object shape, even in the absence of concurrent shape-related visual input. …”

Attentional modulation of perceptual grouping in human visual cortex: ERP studies. by Han, S, Jiang, Y, Mao, L, Humphreys, G, Qin, J

“…Moreover, our ERP results indicate that the neural bases underlying perceptual grouping in human visual cortex can be modulated by task relevance and attention as early as 100 ms after sensory stimulation. …”

Attentional modulation of perceptual grouping in human visual cortex: functional MRI studies. by Han, S, Jiang, Y, Mao, L, Humphreys, G, Gu, H

“…The findings reveal the neural basis for basic grouping operations, as well as illustrating how attention and proximity grouping interact in human visual cortex.…”

Loss of the visual object recognition does not disrupt tactile recognition: evidence for direct tactile activation of visual cortex by Allen, H, Humphreys, G

A computational neuroscience account of visual neglect by Heinke, D, Deco, G, Zihl, J, Humphreys, G

“…The model is based on the "biased competition hypothesis" and is structured in several network modules which are related to the dorsal and ventral pathway in the visual cortex. By damaging the model, visual neglect can be simulated and explained as an unbalanced neurodynamical competition. …”

Impaired visual sensitivity within the ipsilesional hemifield following parietal lobe damage. by Snow, J, Miranda, R, Humphreys, G

“…The parietal cortex is considered to be part of a network of brain areas that modulates competitive interactions between targets and irrelevant distracters in early visual cortex, however there is currently little causal evidence to support this in human observers. …”

Lower visual field advantage for motion segmentation during high competition for selection. by Lakha, L, Humphreys, G

“…The results are consistent with segmentation of moving targets from static distractors being mediated by dorsal regions of the visual cortex, particularly under conditions of high load (non-canonical patterns). …”

Reflexive and preparatory selection and suppression of salient information in the right and left posterior parietal cortex. by Mevorach, C, Humphreys, G, Shalev, L

“…Attentional cues can trigger activity in the parietal cortex in anticipation of visual displays, and this activity may, in turn, induce changes in other areas of the visual cortex, hence, implementing attentional selection. …”
