Hippocampal networks link temporally contiguous memories through spiking sequences that encode sensory cues (external world) and time between them (internal representations), constructing ‘memory-maps’ of related experiences. It was recently shown that such sequences combine particularly stable representations of sensory cues with highly dynamic, learning- dependent temporal-codes. This combination of stability and flexibility allows linking fixed elements of the external world across variable time intervals. But how does feedback inhibition by parvalbumin- (PV) and somatostatin-expressing (SO
