| الوصف: | Objective: \ud Time-based prospective memory (PM), remembering to do something at a particular\ud moment in the future, is considered to depend upon self-initiated strategic monitoring,\ud involving a retrieval mode (sustained maintenance of the intention) plus target checking\ud (intermittent time checks). The present experiment was designed to explore what brain\ud regions and brain activity are associated with these components of strategic monitoring in\ud time-based PM tasks.\ud Method: \ud 24 participants were asked to reset a clock every four minutes, while performing a foreground\ud ongoing word categorisation task. EEG activity was recorded and data were decomposed\ud into source-resolved activity using Independent Component Analysis. Common brain\ud regions across participants, associated with retrieval mode and target checking, were found\ud using Measure Projection Analysis.\ud Results: \ud Participants decreased their performance on the ongoing task when concurrently performed\ud with the time-based PM task, reflecting an active retrieval mode that relied on withdrawal of\ud limited resources from the ongoing task. Brain activity, with its source in or near the anterior\ud cingulate cortex (ACC), showed changes associated with an active retrieval mode including\ud greater negative ERP deflections, decreased theta synchronization, and increased alpha\ud suppression for events locked to the ongoing task while maintaining a time-based intention.\ud Activity in the ACC was also associated with time-checks and found consistently across participants;\ud however, we did not find an association with time perception processing per se.\ud Conclusion: \ud The involvement of the ACC in both aspects of time-based PM monitoring may be related to\ud different functions that have been attributed to it: strategic control of attention during the\ud retrieval mode (distributing attentional resources between the ongoing task and the timebased\ud task) and anticipatory/decision making processing associated with clock-checks. |
