According to conventional views, holding information in working memory (WM) involves elevated and persistent neuronal firing. This has been challenged by models in which WM maintenance is implemented by activity-silent synaptic mechanisms. A new study suggests that both have a role, consistent with cognitive models positing several states of WM. However, do these states reflect the operation of attention or awareness?
