The stimulus intensities are adjusted so that S1 activates fewer fibres than S2.

Klinokinesis: in which the frequency or rate of turning is proportional to stimulus intensity.

By functioning in this manner, a sense organ can work over far greater ranges of stimulus intensity than would otherwise be possible.

Fechner's law states that subjective sensation is proportional to the logarithm of the stimulus intensity.

N1 is also sensitive to the manipulation of a visual stimulus' intensity.

Thus, the stimulus intensities are based on various fibers.

Neural adaptation is also tied very closely to stimulus intensity, whereas habituation is not.

They steadily increase their firing rate as the stimulus intensity rises into the noxious range.

There is also a strong correlation between the stimulus intensity and the intensity of referred and local pain.

In most sensory systems, the firing rate increases, generally non-linearly, with increasing stimulus intensity.
