“…Electrophysiological recordings from human visual cortex were carried out with electrodes chronically implanted in 13 patients for localization of an epileptogenic focus. …”

Imagery for shapes activates position-invariant representations in human visual cortex. by Stokes, M, Saraiva, A, Rohenkohl, G, Nobre, A

“…We argue that a general model of top-down control must account for dynamic modulation of functional connectivity between high-level control centres and overlapping neural codes in visual cortex.…”

Human extrastriate visual cortex and the perception of faces, words, numbers, and colors. by Allison, T, McCarthy, G, Nobre, A, Puce, A, Belger, A

Shape-specific preparatory activity mediates attention to targets in human visual cortex by Stokes, M, Thompson, R, Nobre, A, Duncan, J

“…Influential theories suggest that attentional biases are mediated via preparatory activation of task-relevant perceptual representations in visual cortex, but the neural evidence for a preparatory coding model of attention remains incomplete. …”

Shape-specific preparatory activity mediates attention to targets in human visual cortex. by Stokes, M, Thompson, R, Nobre, A, Duncan, J

“…Influential theories suggest that attentional biases are mediated via preparatory activation of task-relevant perceptual representations in visual cortex, but the neural evidence for a preparatory coding model of attention remains incomplete. …”

Temporal expectation enhances contrast sensitivity by phase entrainment of low-frequency oscillations in visual cortex. by Cravo, A, Rohenkohl, G, Wyart, V, Nobre, A

“…The concurrent electrophysiological data revealed that the phase of delta oscillations overlying human visual cortex (1-4 Hz) was predictive of the quality of target processing only in regular streams of events. …”

Long-term memory prepares neural activity for perception. by Stokes, M, Atherton, K, Patai, E, Nobre, A

“…Next, we examine oscillations in EEG to show that memory-guided attention is associated with spatially specific desynchronization of alpha-band activity over visual cortex. Additionally, we use functional MRI to confirm that target-predictive spatial information stored in LTM triggers spatiotopic modulation of preparatory activity in extrastriate visual cortex. …”

Auditory evoked visual awareness following sudden ocular blindness: an EEG and TMS investigation. by Rao, A, Nobre, A, Alexander, I, Cowey, A

“…Neurophysiological and neuroanatomical studies have provoked controversy about whether the visual cortex may be more modifiable than previously believed. …”

Face recognition in human extrastriate cortex. by Allison, T, Ginter, H, McCarthy, G, Nobre, A, Puce, A, Luby, M, Spencer, D

“…Twenty-four patients with electrodes chronically implanted on the surface of extrastriate visual cortex viewed faces, equiluminant scrambled faces, cars, scrambled cars, and butterflies. 2. …”

Selection mechanisms for working memory by Wallis, G, George Wallis

“…The pattern of alpha (8-12Hz) power in visual cortex was modulated by cue direction following both precues and retrocues, but whilst this modulation was sustained following a precue (until presentation of the memory array) it was transient following a retrocue, suggesting that a memory representation was briefly retrieved or refreshed, but that there was not a sustained biasing of top-down input to visual cortex following retrocues. …”

Filtering of distractors during visual search studied by positron emission tomography. by Nobre, A, Sebestyen, G, Gitelman, DR, Frith, C, Mesulam, M

“…Selective filtering of foils affected visual processing in ventral areas associated with object recognition and in primary visual cortex.…”

Modulation of human extrastriate visual processing by selective attention to colours and words. by Nobre, A, Allison, T, McCarthy, G

“…The present study investigated the effect of visual selective attention upon neural processing within functionally specialized regions of the human extrastriate visual cortex. Field potentials were recorded directly from the inferior surface of the temporal lobes in subjects with epilepsy. …”

Qualitative mapping of cerebral blood flow and functional localization with echo-planar MR imaging and signal targeting with alternating radio frequency. by Edelman, R, Siewert, B, Darby, D, Thangaraj, V, Nobre, A, Mesulam, M, Warach, S

“…CBF changes in the motor strip, primary visual cortex, and the motor area for eye movements were well localized to the cortical gray matter ribbon. …”

Neural markers of category-based selective working memory in aging by Mok, R, O'Donoghue, C, Myers, N, Drazich, E, Nobre, A

“…Activation levels in category-sensitive visual cortex showed reliable modulation according to attentional demands, and positively correlated with subsequent memory measures of attention and WM span. …”

The role of cortical oscillations in the control and protection of visual working memory by Myers, N

“…</p> <p>When information is of particular importance, anticipatory attention can be directed to where it will likely appear. Oscillations in visual cortex, in the 10-Hz range, play an important role in regulating excitability of such prioritized locations. …”
