Schematic illustration of theta flickering. (a) Rats are trained for several days in two boxes (A and B) having different cues and develop uncorrelated neural populations in hippocampal area CA3 that fire preferentially in either A or B. After training, rats are ‘teleported’: they start in one environment (e.g. box A) but the cues are instantaneously switched to those of the other environment (e.g. box B). (b) After ‘teleporting’, distinct neural populations tend to be active at each theta cycle, which fire preferentially in A or B. (c) Example from [118] showing that neural populations code for spatial locations coherent with the actual animal position (indicated by +) in either the correct box B or the incorrect box A, at different theta cycles.
