The impact of early visual cortex transcranial magnetic stimulation on visual working memory precision and guess rate
Neuroimaging studies have demonstrated that activity patterns in early visual areas predict stimulus properties actively maintained in visual working memory. Yet, the mechanisms by which such information is represented remain largely unknown. In this study, observers remembered the orientations of 4 briefly presented gratings, one in each quadrant of the visual field. A 10Hz Transcranial Magnet...
متن کاملAssessing the Effect of Early Visual Cortex Transcranial Magnetic Stimulation on Working Memory Consolidation
Maintaining visual working memory (VWM) representations recruits a network of brain regions, including the frontal, posterior parietal, and occipital cortices; however, it is unclear to what extent the occipital cortex is engaged in VWM after sensory encoding is completed. Noninvasive brain stimulation data show that stimulation of this region can affect working memory (WM) during the early con...
متن کاملInvestigating via Transcranial Magnetic Stimulation (TMS) the interaction between Visual Short Term Memory (VSTM) and mental imagery in the Early Visual Cortex (EVC)
Visual mental imagery and visual short term memory are often assumed to play similiar roles. There are many evidence showing that they both involve visual cortical neurons which encode incoming sensory information. On the cognitive level it has been explained in terms of the visual cache, which is nvolved in the maintenance of visual short term memory and imagery content. Even though menatl ima...
متن کاملTopographic contribution of early visual cortex to short-term memory consolidation: a transcranial magnetic stimulation study.
The neural correlates for retention of visual information in visual short-term memory are considered separate from those of sensory encoding. However, recent findings suggest that sensory areas may play a role also in short-term memory. We investigated the functional relevance, spatial specificity, and temporal characteristics of human early visual cortex in the consolidation of capacity-limite...
متن کاملCausal evidence for a privileged working memory state in early visual cortex.
Emerging evidence suggests that items held in working memory (WM) might not all be in the same representational state. One item might be privileged over others, making it more accessible and thereby recalled with greater precision. Here, using transcranial magnetic stimulation (TMS), we provide causal evidence in human participants that items in WM are differentially susceptible to disruptive T...
