Visual Attention: The Thalamus at the Centre?
نویسنده
چکیده
New work shows that spatial attention modulates visual responses of single neurons in monkey thalamus, providing empirical support for a long-standing theoretical prediction that specific thalamic nuclei play a key role in controlling the spotlight of visual attention.

Thalamic Control of Human Attention Driven by Memory and Learning
The role of the thalamus in high-level cognition-attention, working memory (WM), rule-based learning, and decision making-remains poorly understood, especially in comparison to that of cortical frontoparietal networks [1-3]. Studies of visual thalamus have revealed important roles for pulvinar and lateral geniculate nucleus in visuospatial perception and attention [4-10] and for mediodorsal tha...
متن کاملGuarding the gateway to cortex with attention in visual thalamus
The massive visual input from the eye to the brain requires selective processing of some visual information at the expense of other information, a process referred to as visual attention. Increases in the responses of visual neurons with attention have been extensively studied along the visual processing streams in monkey cerebral cortex, from primary visual areas to parietal and frontal cortex...
متن کاملAttentional modulation of thalamic reticular neurons.
The major pathway for visual information reaching cerebral cortex is through the lateral geniculate nucleus (LGN) of the thalamus. Acting on this vital relay is another thalamic nucleus, the thalamic reticular nucleus (TRN). This nucleus receives topographically organized collaterals from both thalamus and cortex and sends similarly organized projections back to thalamus. The inputs to the TRN ...
متن کاملCognitive and Perceptual Functions of the Visual Thalamus
The thalamus is classically viewed as passively relaying information to the cortex. However, there is growing evidence that the thalamus actively regulates information transmission to the cortex and between cortical areas using a variety of mechanisms, including the modulation of response magnitude, firing mode, and synchrony of neurons according to behavioral demands. We discuss how the visual...
متن کاملSpatially Distributed Encoding of Covert Attentional Shifts in Human Thalamus
Spatial attention modulates signal processing within visual nuclei of the thalamus--but do other nuclei govern the locus of attention in top-down mode? We examined functional MRI (fMRI) data from three subjects performing a task requiring covert attention to 1 of 16 positions in a circular array. Target position was cued after stimulus offset, requiring subjects to perform target detection from...
