a graph of neuronal reaction as an operation of a ongoing stimulant attribute, like wavelength,, orientation, or frequency. A neuron is thought to be "tuned" for the stimulant which induces the largest reaction, and the width of the curve from the half-maximum reaction on either side of the peak indicates how widely or narrowly tuned a neuron is for a particular stimulant attribute. With regard to the auditory system, it is a gauge of frequency selectivity.

TUNING CURVE: "The tuning curve could be lowered slightly without much impact on other variables."
