Neuro-Triggered Training
Abstract
Cortical neuroelectric patterns during a working memory task differed from a control task during two of four split-second intervals when access to the contents of working memory is assumed to take place. Prefrontal cortical areas were prominent among those differentially activated by working memory in these two intervals, which included a prestimulus preparatory interval and a late poststimulus response-inhibition interval. By contrast, patterns were similar between conditions during an early poststimulus interval and during a response interval, when the predominant activity was related to stimulus encoding or response execution. These results suggest that working memory is a dynamic process embodied in neuroelectric activity patterns distributed across the neural areas involved in performing a particular task. The active aspect of short-term memory, termed 'working memory' by A. Baddeley and co-workers, provides the basis for consciously directed perception, cognition and action, attentional programs, and extended logical and linguistic operations.
