GABA and glutamate in hMT+ link to individual differences in residual visual function after occipital stroke by Willis, HE, Ip, IB, Watt, A, Campbell, J, Jbabdi, S, Clarke, WT, Cavanaugh, MR, Huxlin, KR, Watkins, KE, Tamietto, M, Bridge, H

“…We then measured and assessed the strength of relationships between participants’ residual vision in their blind field and in vivo neurotransmitter concentrations, as well as visually evoked functional magnetic resonance imaging activity in their hMT+. Levels of GABA and glutamate were also measured in a sensorimotor region, which served as a control.…”

Vivid visual mental imagery in the absence of the primary visual cortex. by Bridge, H, Harrold, S, Holmes, E, Stokes, M, Kennard, C

“…In this study, we show that in spite of his near-complete cortical blindness, SBR exhibits vivid visual mental imagery both behaviorally and when measured with functional magnetic resonance imaging. The pattern of cortical activation to visual mental imagery in SBR is indistinguishable from individual sighted subjects, in contrast to the visual perceptual responses, which are greatly attenuated.…”

Testing the inter-hemispheric competition account of visual extinction with combined TMS/fMRI by Petitet, P, Noonan, M, Bridge, H, O'Reilly, J, O'Shea, J

“…We tested these claims using low-frequency offline transcranial magnetic stimulation (TMS) to transiently inhibit activity in the right angular gyrus/intra-parietal sulcus, followed by a visual detection task to assess changes in attentional bias, and functional magnetic resonance imaging (fMRI) to test for the predicted leftward shift in brain activity. …”
