Broadband high frequency Activity initializes Distractor Suppression

|
By Paul Schmid, Christoph Reichert, Mandy Viktoria Bartsch, Stefan Duerschmid
| BioRxiv
Abstract Selective attention requires fast and accurate distractor suppression. We investigated if broadband high frequency activity (BHA; 80 to 150 Hz), indicative of local neuronal population dynamics in early sensory cortices, indexes rapid processing of distracting information. In the first experiment we tested whether BHA distinguishes targets from distracting information in a visual search paradigm using tilted gratings as targets and distractors.

Serial attentional resource allocation during parallel feature value tracking

|
By Christian Merkel, Mircea Ariel Schoenfeld, Luise Burgmann, Mandy Viktoria Bartsch
| BioRxiv
Abstract The visual system has evolved the ability to track features like color and orientation in parallel. This property aligns with the specialization of processing these feature dimensions in the visual cortex. But what if we ask to track changing feature-values within the same feature dimension? Parallel tracking would then have to share the same cortical representation, which would set strong limitations on tracking performance.
