To compare the timing for oscillation of ILI in GOPC and ILI in GP to influenza activity, we calculated their phase difference at the annual cycle (52-week periodic band), which was the only cycle consistently evident throughout the whole study period.
Further, the precise timing of the oscillations differs depending on the cell system (integrated versus episomal reporter) and assay (real time PCR versus reporter) which may reflect differences in the precision inherent with each technique.
Some of these factors have been related to the timing of Ca2+ oscillations in mouse oocytes (24).
The timing of these oscillations was similar to 6.5 hr cells in control mixes, in support of the model.
From the cell class-specific theta-related firing of PV interneurons described above and the relative timing of epsilon oscillations during theta, we predicted that AACs were unlikely to be strongly modulated by these running-associated high-frequency oscillations.
However, the association of the timing of these oscillations to the different body postures is difficult because a simultaneous recording of e.g. the position of the arms and the ECG was not available.
Fast-spiking PV cells are neurons that orchestrate the precise timing of these oscillations in a region of the brain called the hippocampus, which is important for the formation of memories.
We first identify the timing of cortical oscillations responsible for rest tremor in the periphery by delivering tremor-frequency stimulation over motor cortex but do not couple this stimulation to the on-going tremor instead, the rhythms simply "drift" in and out of phase alignment with one another.
We obtained three individual-level cosine parameters that quantity the circadian pattern: mean (M), measures the overall average of a HRV index; amplitude, measures the amplitude of the oscillation of a HRV index; and acrophase time, measures the timing of the highest oscillation.
For example, reduced Scn8a activity may directly increase burst firing of thalamic relay neurons, as suggested for other excitatory neurons, or enhance activity of inhibitory neurons of the reticular thalamic nucleus in a manner suggested for GluR4 mutant mice with SWD (18), producing prolonged inhibition and affect the timing of the thalamocortical oscillation.
