Document Summary
Information processing the processing of an input to creat an output is done by single neurons and neural circuits. One of the major forms of very simple information processing. Once the stimuli is turned on, it is constant (sensory or direct) As the stimulus gets larger and larger, the amplitude of the stimulus is encoded by the spike frequency (frequency coding). Your perception of the amplitude of the stimulus (loudness of a sound; brightness of a light) is a function of the frequency of action potentials going to that part of the brain. The spike frequency does not remain constant even if the stimulus does. You see a dramatic decrease in the spike frequency over time in the face of a constant stimulus=spike frequency adaptation. A constant sound in the background goes away with time, you get used to it. In the touch receptors in your skin, looking for your glasses.
