In recent years, a diversity of methods have been proposed for reversibly inactivating neurons [19] [26]; the majority of these methods rely upon chemical delivery and washout to temporally delimit the duration of inactivation, which accordingly limits the induction and reversal kinetics to periods of at least several minutes or hours.
A given interval always can be subdivided into a sequential chain delimiting briefer durations, as with the regular units that provide empirical measures of time: the second, the day, the year.
Fourth, we might target atoms, or momentary experiencers, "units" defined and delimited by the duration of an experience.
Duration of tracheid formation was delimited by day of the year, when onset and end of cell enlargement was detected.
An empty interval is bounded by two perceptually discrete stimuli (e.g., two clicks in succession); a duration is full when there is continous stimulation, being delimited by an onset and cessation (e.g., a light stays on throughout the interval).
A commonly observed phenomenon to elucidate distortions of perceived duration is the filled-duration illusion: a temporal interval delimited by two marker signals is perceived to be shorter than the same interval with several identical filler signals.
PA was delimited to light, moderate, and vigorous activity of at least 10-min duration.
Once the characteristic properties of the data were delimited, the synthetic data were created by randomly sampling from a range of mean durations from 0.0 to 10.0 units.
Figure3 also shows particular cases where the active duration (defined by the AO parameter) takes special significance in the transmission bitrate, delimiting the maximum hop distance for delivering data.
The duration of exploration of each goal box (when the mouse is sniffing the grid delimiting the goal box) was measured, and the percentage of time the mouse took to explore the congener was used as an index of social preference (recognition preference).
