Using biologically plausible neural models to specify the functional and neural mechanisms of visual search (2009)
Journal Article
Humphreys, G. W., Allen, H. A., & Mavritsaki, E. (2009). Using biologically plausible neural models to specify the functional and neural mechanisms of visual search. Progress in Brain Research, 176, https://doi.org/10.1016/S0079-6123%2809%2917609-4

We review research from our laboratory that attempts to pull apart the functional and neural mechanisms of visual search using converging, inter-disciplinary evidence from experimental studies with normal participants, neuropsychological studies with...

Ventral extra-striate cortical areas are required for human visual texture segmentation (2009)
Journal Article
Allen, H. A., Humphreys, G. W., Colin, J., & Neumann, H. (2009). Ventral extra-striate cortical areas are required for human visual texture segmentation. Journal of Vision, 9(9), Article 2. https://doi.org/10.1167/9.9.2

A patient (HJA) with bilateral occipital lobe damage to ventral cortical areas V2, V3 and V4 was tested on a texture segmentation task involving texture bar detection in an array of oriented lines. Performance detecting a target shape was assessed as... Read More about Ventral extra-striate cortical areas are required for human visual texture segmentation.

Direct tactile stimulation of dorsal occipito-temporal cortex in a visual agnosic (2009)
Journal Article
Allen, H. A., & Humphreys, G. W. (2009). Direct tactile stimulation of dorsal occipito-temporal cortex in a visual agnosic. Current Biology, 19(12), https://doi.org/10.1016/j.cub.2009.04.057

The human occipito-temporal cortex is preferentially activated by images of objects as opposed to scrambled images [1]. Touching objects (versus textures) also activates this region [2–10]. We used neuropsychological fMRI to probe whether dorsal regi... Read More about Direct tactile stimulation of dorsal occipito-temporal cortex in a visual agnosic.
