Wolf, N. F., Gales, M., Shane, E., & Shane, M. (2000), Fear memories require protein synthesis in the amygdala for reconsolidation after retrieval. Nature, 406:722-726. This paper introduces the physiological basis for an important novel concept in our understanding of memory consolidation. The finding suggests that the process of retrieving a memory opens it up to the potential for disruption before reconsolidation. Thus, a memory (in this case for fear), which has already been well encoded, can be “erased” when disrupted during retrieval. In this experiment, rats were amnesic for previously learned items when a drug (anisomycin) was administered during memoryretrieval. The effect was found to be equally effective from 1 to 14 days after training. In narrow terms, the finding is probably one of the physiological bases for the reason that recall is more a process of active “remembering,” than one of passive recall of a fixed memory. In more general terms, it offers the physiological foundation for the range of well-described manipulations and distortions of memory (cf. Nachtraglichkeit), which are well known in the psychological literature (for example in the work of Elizabeth Loftus).
