(A) An alternation task maze. Purple: an example episode field sequence. Green: an example place field sequence. Each dot represents the peak of an episode/place field. (B) An example SPW event. …
(A) Example SPW event before (black) and after (blue) the inactivation. (B) Locations of SPW events before (left) and after (right) the inactivation. (C) Frequency of SPW events before (Pre) and …
(A) Left: Example episode field sequence before (purple) and after (blue/purple) MS inactivation. Right: example SPW sequences correlated with the pre-injection episode field sequence recorded …
(A) Relationship between animal performance in the task and percentage of significant sequence replay before (Pre) and after (Musc) MS injection. (B) Frequency of sequence replay before (x-axis) and …
(A) Left: example electrode-signal with theta oscillations. One theta cycle is magnified (red). Right: example SPW event. (B) Left: example sequences generated during individual cycles of theta …
In this analysis we eliminated all spikes from each burst except for the first one. We did not observe any drop in the prevalence of SPW replay during Muscimol. The chance level (dash line) is …
In this analysis we shuffled the identity of cells and time stamps but preserved the autocorrelation function of each cell. The chance level (dash line) is determined by the mean of the percentages …
In this analysis we shuffled the identity of neurons without altering the spike timing. The chance level (dash line) is determined by the mean of the percentages of significant replay observed in …
Mean frequency of replay ± SEM: | Pre | Muscimol |
Correct trials | 0.22Hz ± 0.014 | 0.32Hz ± 0.024 |
Error trials | 0.5Hz ± 0.08 | 0.85Hz ± 0.25 |
