The inferior collicular (IC) response has been studied in several species of myomorph rodent previously investigated at a cochlear level. In most cases the cochlear microphonic (CM) response has been obtained from the same individuals. The results obtained showed that the peak already found in the CM response at high frequencies was far greater at the level of the inferior colliculus (Figs. 2–5), and showed good correspondence in frequency with ultrasounds produced by the species concerned (Table 2).
Careful controls were made for factors which may have affected the response. Body temperature, in particular, was shown to have a marked effect on the high frequency response (Fig. 10).
