Conclusions
-
1.
The limiting frequency of modulation of the amplitude of the stimulus at which differentiation between tonal and amplitude-modulated stimuli is still possible, detectable after bilateral ablation of the auditory cortex of the rat brain, does not change following bisection of the brachia of the posterior colliculus.
-
2.
Bilateral ablation of the auditory cortex and section of the brachia of the posterior colliculus in rats completely impair differentiation between the tonal stimulus and the amplitude-modulated signals with a modulation frequency below 27–31 Hz, and have no effect on the differentiation between tonal and amplitude-modulated signals with modulation frequencies above 27–31 Hz.
