Alpha power gates relevant information during working memory updating.
Human working memory (WM) is inherently limited, so we must filter out irrelevant information in our environment or our mind while retaining limited important relevant contents. Previous work suggests that neural oscillations in the alpha band (8-14 Hz) play an important role in inhibiting incoming distracting information during attention and selective encoding tasks. However, whether alpha pow...
متن کاملMultiple gates on working memory.
The contexts for action may be only transiently visible, accessible, and relevant. The corticobasal ganglia (BG) circuit addresses these demands by allowing the right motor plans to drive action at the right times, via a BG-mediated gate on motor representations. A long-standing hypothesis posits these same circuits are replicated in more rostral brain regions to support gating of cognitive rep...
متن کاملComponents of Working Memory Updating
Working memory updating (WMU)—the ability to maintain accurate representations of information changing over time— has been successfully used in individual differences research to predict higher cognitive abilities. For instance, WMU has been found to predict fluid intelligence and reading comprehension. However, little is known about the underlying component processes of WMU or the relationship...
متن کاملUpdating visual–spatial working memory during object movement
Working memory enables temporary maintenance and manipulation of information for immediate access by cognitive processes. The present study investigates how spatial information stored in working memory is updated during object movement. Participants had to remember a particular location on an object which, after a retention interval, started to move. The question was whether the memorized locat...
متن کاملEEG alpha power during maintenance of information in working memory in adults with ADHD and its plasticity due to working memory training: A randomized controlled trial.
OBJECTIVE The present study examined whether neural indices of working memory maintenance differ between young adults with ADHD and their healthy peers (Study 1), and whether this neural index would change after working memory training (Study 2). METHODS Study 1 involved 136 college students with ADHD and 41 healthy peers (aged 18-35 years) and measured their posterior alpha activity during a...
