The olfactometer can present either solid or liquid odor sources, and it exhibits a fast stimulus-rise time and a fast and stable stimulus-onset time.
Here, we show that event-related NIRS is able to detect age-related differences in the neural processing in a simple visual Go/NoGo task using a relatively fast (stimulus onset asynchrony approx. 1.4 s) event-related design together with a model-based analysis approach.
The latency of activation in that area is 28 32 ms after onset of a fast moving stimulus (> 10 °/s) and 74 ms after onset of a slow moving stimulus (< 5 °/s; ffytche et al., 1995); hence V5 is activated before V1 with the former and after it with the latter, a finding that flashed stimuli would not have revealed.
Depending on the nature of an experiment, it is important to know the measurement accuracy averaged over a large number of samples (e.g., when you are tracking a slow moving or static stimulus) or to know the measurement accuracy for single samples (e.g., when you are tracking a fast moving stimulus).
Selective listening at fast stimulus rates: so much to hear, so little time.. Electroencephalography and Clinical Neurophysiology.
Furthermore, during normal reading, rapid input rates of four to five words per second require high perceptual efficiency and encourage fast stimulus processing.
We compared speeded and delayed responses and expected only the former to modulate eGBRs, since speeded responses can only be based on fast stimulus discriminations.
To identify the origin of the observed SSDW components we next varied the retinal position of the stimuli in the fast stimulus sequence.
In contrast to the fronto-central peaks, the T-complex peaks appear less sensitive to stimulus rate as they can be recorded in young children even with fast stimulus presentation (Gomes et al., 2001).
It is possible that these fatal factors could have been avoided by better vetting from DOE, or that removed from the pressures of a fast-paced stimulus environment, DOE may not have made this bad bet.
