DOI: http://dx.doi.org/10.7554/eLife.08969.011 Following auditory fear conditioning the latency of responses to a conditioned stimulus decreases in the LA (Quirk et al., 1995; Maren, 2000).
Aging has been reported to decrease memory to an aversive stimulus (decreased freezing) in context- and cue-dependent fear response [ 31- 34].
In addition, analyses of a series of single-epoch data from a single individual revealed a stimulus-by-stimulus decrease in the activation in the anterior cingulate cortex that paralleled the decrease in the subject's psychophysical responses.
Over 90 s of the test, flies' preference for a previously shock-paired visual stimulus is decreased in comparison to an unpaired visual stimulus.
Finally, because responses from the same cell could be compared across stimulus intensities, these data show that the absolute number of responding cells becomes more sparse as the stimulus strength decreases in control animals.
As acclimatisation develops, constant workload exercise protocols may result in a progressively lower training stimulus (ie, decreases in relative exercise intensity).
The interaction of Stimulus and Age occurred due to decrease in N170 latency associated with infrequent stimuli with increasing age (6 7 years > 8 9 years, p = 0.024; 8–9 years > 10 12 years, p = 0.024): this was irrespective of laterality.
As expected, as the interval is increased, the interaction between the stimuli decreases, resulting eventually in a paired-pulse ratio close to one.
As Maspin enhances cellular sensitivity to apoptotic stimuli, decreased Maspin expression in Atf-2 heterozygotes could contribute to immortalization by the abrogation of apoptosis.
When a stimulus is anticipated or attention is directed toward the location of a stimulus, alpha power decreases in visual, auditory or somatosensory cortex, respectively, contralateral to the expected or (covertly) attended site.
Animals develop hyperalgesia to thermal stimulus (hot plate), decreases in grip force lasting for up to 9 days and enhanced response to inflammatory stimuli (formalin and carrageenan) (male rats) [ 59- 61].
