The phrase "an increased stimulus" is correct and usable in written English.
It can be used in contexts discussing changes in stimuli, such as in psychology, biology, or economics, where a stimulus is heightened or amplified.
Example: "The experiment showed that an increased stimulus led to a more pronounced response in the subjects."
Alternatives: "a heightened stimulus" or "an amplified stimulus".
Furthermore, the frequency of APs within the initial burst tends to increase with increased stimulus intensity.
Johnson et al. (2008) reported that spatially very close clusters of activation showed very different responses to novelty: one cluster showed a categorical difference between new items and old items whereas the other cluster showed a linear response decrement as a function of increased stimulus familiarity.
Evoked KCs are suggested to originate from a brain state with relatively increased stimulus processing, revealing an activity pattern resembling novelty processing as previously reported during wakefulness.
In the group-level whole-brain analysis, a linearly weighted parametric contrast identified 3 clusters in the occipital cortex that exhibited a gradual increase in BOLD responses with increased stimulus durations (Fig. 8 and Supplementary Table 4).
Several brain regions, including the striatum and anterior cingulate, previously associated with mental set switching were found to be related more to resolving intra-stimulus interference conferred by increased stimulus complexity and increased motor response complexity than to executing the mental set switch.
In Experiment 1, we systematically tested for a paradoxically decreased response to increased stimulus size in the vicinity of LTC, and (as a control) throughout the brain.
One potential explanation for the insensitivity of the left calcarine ROI is that the BOLD response was not sensitive to the increase in visual input with increased stimulus durations because of saturation.
Of course, the between-experiment difference represents an expected result owing to the increased stimulus response alternatives used here [38] [39].
Fig. 4 displays a negative staircase of peak shortening (PS) with increased stimulus frequency in all 4 groups with a steeper decline in PS in both ethanol-treated groups (although PS decline in FVB-EtOH group failed to reach significant level between 1 and 5 Hz).
Mammary glands from WAP-Brk transgenic mice exhibited higher phospho-p38 levels relative to wild-type glands during Days 4 and 6 of the involution time course, again consistent with an increased survival stimulus in WAP-Brk mice.
