1999) requires recurrent activation of hippocampal ionotropic glutamate receptors for about 1 week following conditioning, which led to the synaptic re-entry reinforcement hypothesis of memory consolidation (Wittenberg and Tsien 2002). Obviously, it seems to be an evolutionary advantage to delay memory consolidation until the signiﬁcance of an experience could be evaluated. In fact, events that precede or follow memory acquisition are able to interrupt the consolidation process by proactive and retroactive inhibition (Xu et al.

However, only a small subset of neurones or even synapses of a given neurone might be involved in a distinct memory process, and neurones are highly heterogeneous in their gene expression proﬁles (Kamme et al. 2003; Levsky and Singer 2003). Consequently, the signal-to-noise ratio would be very small on average over whole brain structures, making subtle changes in gene expression, expected for learning events, hard to detect (Geschwind 2000). The role of the amygdala for consolidation of aversive memories is generally accepted.
