To define stimulus-related activity, each spike was smoothed with a Gaussian kernel (sigma = 10 ms; width 3 sigma), followed by ANOVA comparing each 1-ms bin of poststimulus activity with equivalent data sampled from the prestimulus period (20, 1-ms samples prior to each stimulus onset, spaced 10 ms apart over the period 10- to 200-ms prestimulus).
The ability of an ion channel to open in response to a defined stimulus is central to its function.
The response indicative of learning was the selection of the blank comparison, which indicates that the participant identified the figure presented in the exclusion trial as a defined stimulus and therefore not corresponding to the new undefined name dictated in the trial.
Lines connecting individual data points indicate ethologically defined stimulus categories.
In the tissue culture model there is a single cell type and a clearly defined stimulus.
This is in contrast to a reflex, where a defined stimulus gives an invariant response.
This aspect, if integrated in a network, may give hints about the temporal activation of metabolic pathways under a defined stimulus in different compartments.
Investigation of the basal synaptic transmission was performed by correlating fEPSP sizes to defined stimulus intensities (input-output curve, 8-22 μA in steps of 2 μA).
However, individual sensory responses in the MeA rarely form sharply defined stimulus categories, but rather, maintain enough information to distinguish between individual elements of each category.
Dentin hypersensitivity might either be evaluated in terms of a stimulus intensity required to provoke pain (stimulus-based assessment) or as a subjective evaluation of the pain produced by a defined stimulus (response-based assessment) [ 30, 33, 68].
For EA stimulation, eight discrete blocks of EA stimuli were applied (stimulation duration = 6 sec, ISI = 60 sec, total length = 480 sec, Figure 2B) using the previously defined stimulus frequency and current intensity.
