  • Title: [Responses of bat cochlear nucleus neurons to ultrasonic stimuli].
    Author: Vasil'ev AG, Grigor'eva TI.
    Journal: Neirofiziologiia; 1977; 9(1):41-7. PubMed ID: 840328.
    Abstract:
    The responses of cochlear nuclei single units in Vespertilionidae and Rhinolophidae were studied by means of ultrasound stimuli of different frequencies. Most neurons were found to have one or two complementary response areas with best frequencies equal to 1/2 and 1/3 of the highest one (which we regard as the basic best frequency). In Vespertilionidae which emit frequency-modulated signals some neurons have complementary areas with upper thresholds. The latency of responses do not correlate with the stimulus frequency. This suggests that there is no correlative reception of echosignals at this level of auditory system in bats.
