Reaffirming the Sensory Recruitment Account of Working Memory.
of visual information that was initially processed in the conventional visual system. Sensory recruitment, by contrast, provides a parsimonious model of VWM storage, as it decreases redundancy in cortical processing. Imaging studies provide ample support for a shared neural substrate for visual representations of retinal and mnemonic origin, while behavioral studies provide ample support for (e...
متن کاملFunctional connectivity during working memory maintenance.
Neurophysiological experiments with monkeys have demonstrated that working memory (WM) is associated with persistent neural activity in multiple brain regions, such as the prefrontal cortex (PFC), the parietal cortex, and posterior unimodal association areas. WM maintenance is believed to require the coordination of these brain regions, which do not function in isolation but, rather, interact t...
متن کاملMechanisms of Sensory Working Memory: Attention and Perfomance XXV
I was pleased to be asked to visit a remote, beautiful, verdant, and earthy location to give the symposium lecture at a conference on something researchers rarely discuss as such: the sensory aspect of working memory. Is there such a thing? Why is it rarely referred to in this way? First I will discuss terms and what they mean, with a short modern history of the usage of these terms and a gener...
متن کاملMechanisms of Sensory Working Memory: Attention and Perfomance XXV
The amount of visual information an individual can actively represent is severely limited; this limitation is known as the capacity of visual working memory (VWM). To estimate an individual’s VWM capacity, we present an observer with a memory array containing multiple visual stimuli to remember over a relatively short delay interval, after which we test their memory (Figure 1(a)). When we exami...
متن کاملSpatially global representations in human primary visual cortex during working memory maintenance.
Recent studies suggest that visual features are stored in working memory (WM) via sensory recruitment or sustained stimulus-specific patterns of activity in cortical regions that encode memoranda. One important question concerns the spatial extent of sensory recruitment. One possibility is that sensory recruitment is restricted to neurons that are retinotopically mapped to the positions occupie...
