The application range of synthesized test signals is in general limited to the one system the stimuli have been targeted at, because the procedure does not address the effect of implementation changes in the system under test on the measurement results obtained with the synthetic stimuli.
In the auditory system, the stimulus-response properties of single neurons are often described in terms of the spectrotemporal receptive field (STRF), a linear kernel relating the spectrogram of the sound stimulus to the instantaneous firing rate of the neuron.
The rather narrow dynamic range for barrel cortex neurons is quite unusual, as in other sensory systems the stimulus intensity, such as increased visual contrast, increases the spike output across a broad range of firing frequencies, even in anaesthetised animals (Albrecht & Hamilton, 1982).
Some nodes of these networks (in this case those corresponding to cytokines), thanks to their peculiar location in the network architecture, are responsible for the sensitivity aspects, while the large degree of interconnection is at the basis of the resilience properties of the system, here appearing as a global adjustment of the entire system following the stimulus.
The phenomenon does not occur in linear systems, where the addition of noise to either the system or the stimulus only degrades the signal quality.

But the chairman was met at once with sharp questions from the senators, some of whom said they were passing on the resentment they have been hearing from constituents, not necessarily about President Obama's proposed $3.55 trillion budget for the next fiscal year but about the rescue plan for the financial system and the stimulus package.
In this type of bias, the information is already present in the system before the stimulus is observed [3].
An average of target and flanker identities could similarly mimic our results, because averaging the flankers with noise (arising from either the visual system or the stimulus) would also replicate the flanker identity.
Inter-stimulus intervals were 30 s to avoid adaptation of the olfactory system to the stimuli.
