frequency coding
frequency coding[′frē·kwən·sē ‚kōd·iŋ] (neuroscience) A means by which the central nervous system analyzes the content of a receptor message; the frequency of discharged impulses is a function of the rate of rise of the generator current and indirectly of the stimulus strength; the greater the stimulus intensity, the higher the impulse frequency of the message. frequency coding
frequency coding A means by which the central nervous system, limited by the all-or-none properties of nerve impulse conduction, is able to convey information about varying intensity of signals. It does this by employing frequency modulation (FM). The frequency of impulses varies with the strength of the stimulus. |
