The auditory response areas of 192 inferior collicular neurons (IC) of Eptesicus fuscus were studied under free field acoustic stimulation. The boundary of the auditory response area of a neuron expands with stimulus intensity (Fig. 1). However, there is a response center within each neuron's response area at which the neuron has the maximal sensitivity… CONTINUE READING
