The phrase "at the stimulus" is correct and usable in written English.
It can be used in contexts related to psychology, biology, or any field discussing responses to stimuli.
Example: "The subject exhibited a noticeable reaction at the stimulus presented during the experiment."
Alternatives: "in response to the stimulus" or "upon the stimulus".
Republicans have been hammering away at the stimulus.
PAGE B1 REVIEWING THE STIMULUS PACKAGE David Leonhardt takes a look at the stimulus package proposed by President Obama, and finds much to like -- as well as a major flaw.
Subjects were instructed before stimulus onset either to look at the stimulus or to look away from the stimulus.
Children with ASD displayed deficits in low-contrast responses at the stimulus frequency of 12.5 Hz, notably under conditions that emphasized activity in the magnocellular pathway.
This is not to suggest that state-based, national capitalism is inferior, but that it may not apply so well to this vast, highly diversified economy–just look at the stimulus.
For the response at the stimulus frequency, the ASD group produced a relatively constant level of noise across the contrast range tested, with higher levels than controls at low contrasts and approximately equal levels of noise at moderate to high contrasts.
Michelson contrast was 1 at the stimulus center.
The power spectra for individual oscillators show a strong, narrow peak at the stimulus frequency (Figure 6B).
Similarly, TPS50, TPS90, TR50 and TR90 were unaffected by single mutation of APP or PS1 at the stimulus frequency of 0.5 Hz (data not shown).
We sought to measure the amount of information gained by combining successive estimates (i.e., How useful is it to take another glance at the stimulus?).
In the case of CNQX and AP5 administration, the some responses remained both at the stimulus position and at layer 2/3 (see Results).
