Recent evidence has revealed that short-lived internal representations held in visual short-term memory (VSTM) can be modulated by top-down control via retrospective attention which impacts subsequent behavioral performance.

abstract

► We investigated the functional connectivity between the frontal cortex and visual areas. ► More effective top-down modulation increased visual activity. ► Coherency analyses revealed that top-down modulation produced stronger functional connectivity. ► Participants with stronger functional connectivity exhibit better memory performance. ► Augmented functional connectivity strengthens the VSTM representations.

Recent evidence has revealed that short-lived internal representations held in visual short-term memory (VSTM) can be modulated by top-down control via retrospective attention which impacts subsequent behavioral performance. However, the functional inter-regional interactions underlying these top-down modulatory effects are not fully characterized. Here we used event-related functional magnetic imaging to investigate whether the strength of functional connectivity between the frontal cortex and posterior visual areas varies with the efficacy of top-down...
