We found that flies of both sexes aroused during several discrete epochs during the night.
We considered a simple model describing recent fluctuations in effective population size in two or three discrete epochs as well as the single epoch constant size (null) model (see Figure 1).
Thus, the genes isolated from the screen reveal two discrete "epochs" of gene expresssion associated with neural induction by an organizer graft, and these parallel similar phases of gene expression during normal neural plate development.
However, by separating the analyses of data into discrete epochs marked by significant events, we have included those cases whose illnesses straddle epochs.
As opposed to continuous simulation, discrete-event simulation (DES) can test systems that change states at discrete epochs over time [ 17].
The continuous EEG was then segmented into discrete 1,000-ms 1,000-msincluding a 100-ms prepochslus perincludingany epochs containing values exceeding ±75 μV were considered to contain artifacts and were rejected from further analysis.
The delay timing of the paradigm allowed us to divide the trial into discrete time epochs and isolate the sustained plan-related neural responses that evolve prior to movement from the transient visual response (Preview phase) and the movement execution response (Execute phase; Figure 1C,D).
These findings demonstrate that RSNs derived from conventional techniques such as ICA or seed based correlation may be identified from discrete transient epochs that represent only a small fraction of the total recording, confirming recent studies from both fMRI and MEG (Liu and Duyn, 2013; de Pasquale et al., 2012).
In some extracellular recordings, discrete ISO-derived epochs of HT bursting appeared to drive synchronous firing in additional cells, and could be associated with recurrent LFP oscillations in the α (8 13 Hz) band (frequency: 11.3±0.6 Hz; peak-to-peak amplitude: 79.2±4.8 µV; n = 5) (Fig. 2A) [27], [29], [29].
At training session, learning events occur at discrete time periods (learning epochs).
To detect EEG seizures in time domain, there is a need to analyze discrete time sequences of EEG epochs.
