Abstract

The idea that remembering involves an engram, becoming stable and permanent via consolidation, has guided the neuroscience of memory since its inception. The shift to thinking of memory as continuous and dynamic, as part of a trend toward neural dynamics, has challenged this commitment, with some, such as Lynn Nadel, calling for “the demise of the fixed trace” and others, such as Alcino J. Silva, urging rejection of the “consolidation dogma.” Does consideration of neural dynamics offer reasons to reject engram theory? No. I argue that they are compatible. At most, shifting to a dynamic view of neural processes compels revision of the implementational details.
