Dissociating vision and visual attention in the human pulvinar.
The pulvinar region of the thalamus has repeatedly been linked with the control of attention. However, the functions of the pulvinar remain poorly characterized, both in human and in nonhuman primates. In a functional MRI study, we examined the relative contributions to activity in the human posterior pulvinar made by visual drive (the presence of an unattended visual stimulus) and attention (c...
متن کاملAttention gates visual coding in the human pulvinar
The pulvinar nucleus of the thalamus is suspected to have an important role in visual attention, based on its widespread connectivity with the visual cortex and the fronto-parietal attention network. However, at present, there remain many hypotheses on the pulvinar's specific function, with sparse or conflicting evidence for each. Here we characterize how the human pulvinar encodes attended and...
متن کاملPrefrontal contributions to visual selective attention.
The faculty of attention endows us with the capacity to process important sensory information selectively while disregarding information that is potentially distracting. Much of our understanding of the neural circuitry underlying this fundamental cognitive function comes from neurophysiological studies within the visual modality. Past evidence suggests that a principal function of the prefront...
متن کاملExploring the pulvinar path to visual cortex.
The primary pathway for visual signals from the retina to cerebral cortex is through the lateral geniculate nucleus of the thalamus to primary visual cortex. A second visual pathway has been postulated to pass through the thalamic pulvinar nucleus and to project to multiple regions of visual cortex. We have explored this second visual pathway using a method that allows us to identify the inputs...
متن کاملDissecting Spatial Visual Attention
it has been recognized that at least two forms of spatial attention can be found in vision. For example, Wundt (1902) observed that attention could be involuntary or voluntary. A variety of distinctions have been made that more or less correspond to Wundt’s distinction, including goal-directed attention versus stimulus-driven capture and endogenous attention versus exogenous attention. the term...
