Striatal involvement in visual encoding

A capacity limited system, such as the human brain, needs effective strategies to deal with large amounts of incoming information. The theory of visual attention (TVA) allows for formal quantification of specific processes related to selection and recognition of visual information. In the present model-based fMRI study, parameters derived from the TVA-framework were used to determine trial-by-trial changes in the distribution of attention and to relate these to specific cortical attentional networks. Trial-by-trial changes in the single trial likelihood (STL), an inferred variable representing an element's proba…
