  • Values represent mean ± SEM. The table shows the average inhibition and rebound strengths calculated during each brain state. While the pairwise connection strengths between the theta phase-unmodulated cells are significantly different from those of the modulated ones, they do not differ significantly during two different states as can be seen from the table. While the calculation of strengths took them into account, the durations of the inhibition and rebound firing between pairs also did not seem to depend on the state. Typically, duration for statistically significant inhibition was up to 1.6 ms, while the typical rebound duration was ∼2.4 ms.

  • * indicate statistically significant stronger (p < 0.009) average inhibition and weaker (p < 0.002) average rebound excitation strengths for theta phase-modulated neurons in comparison with theta phase-unmodulated neurons.
