Bursting and theta modulation of remapping and stable cells. A, Remapping cells did not have higher burst index scores than stable cells. B, The degree of theta modulation, measured as the mean resultant length of the circular distribution of spike theta phases, was not different between remapping and stable cells. C, However, the mean theta phases of remapping cells were shifted to later phases compared with those of stable cells. *p < 0.05, n.s. indicates not significant.
