Attention 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 کاملDissociating 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 کاملPulvinar-Cortex Interactions in Vision and Attention
The ventro-lateral pulvinar is reciprocally connected with the visual areas of the ventral stream that are important for object recognition. To understand the mechanisms of attentive stimulus processing in this pulvinar-cortex loop, we investigated the interactions between the pulvinar, area V4, and IT cortex in a spatial-attention task. Sensory processing and the influence of attention in the ...
متن کاملPostnatal development of spatial coding in the gravity sensing system
The critical maturation time of central otolith neurons in processing spatial orientations was examined in Sprague-Dawley rats. With the use of immuno-hybridization histochemical methods, we observed c-fos expression in vestibular nuclear neurons responding to transverse movement on the horizontal plane as early as P7 and those to antero-posterior stimulation as early as P9. In the inferior oli...
