We specified the duration of the estimated response from stimulus onset (time = 0) to 18-s poststimulus onset (13 TR), a sufficient duration for the estimated BOLD response to return to baseline, for each separate epoch of the trial.

More recently there was "Snow Flower and the Secret Fan," another bifurcated movie about women in separate epochs, one a past in which women are imprisoned by law and broken feet, the other a present in which they're burdened by ennui and high heels.
News & Media
Since these discoveries are typically rare events, the population dynamics can be subdivided into separate epochs, with rapid transitions between them.
Temporal detrending was essential to remove low-frequency, reproducing time trends; the number of cosine basis functions for detrending was optimized by assuming that separate epochs of baseline scans have constant, equal means, and this assumption was assessed with prediction metrics.
Science
To assess how the selection of outcomes has changed over time, we divided the period 1988 to 2007 into sixteen separate epochs, each lasting five years.
Science
Although adolescents recruited a largely similar neural network as adults throughout the task, including the VS, sPCS, IPL, and middle frontal gyrus, there were distinct developmental differences in activation during separate epochs of the task.
Science
As a brief aside, we find it important to note that these time-resolved decoding results also provide an validation of our past published work (Gallivan et al., 2011a; Gallivan et al., 2011b; Gallivan et al., 2013), which divided the trial into separate epochs for decoding analysis (i.e., Preview, Plan and Execute).
Science
There was no significant difference detected between epochs in the proportion of transferred twins/triplets of 27-28 weeks' gestation who were separated (epoch one, England, Wales, and Northern Ireland: 33% (39/119); epoch two, England: 29% (38/129)), although the small numbers limit power to detect a difference.
Science
What are the features that separate the epochs of the signal that trigger a spike with reliable timing from those that cannot?
We tested spatial exploration and lever pressing for sucrose in separate behavioral epochs within the same recording session.
Science
As a validity check for our deconvolved time courses from the separate trial epochs, we sought to verify that the sum of the individual trial components would result in a typical HDR shape and that the summed response closely matched the time course obtained when considering the trial as a whole.

Common error
Avoid using "separate epoch" when a more general term like "time" or "period" would suffice. Reserve it for instances where emphasizing the distinct nature of the timeframe is crucial.
