Auditory cortical tuning to band-pass noise in primate A1 and CM: A comparison to pure tones

► We compared responses to tones and band-pass noise (BPN) in primate auditory cortex. ► Core area A1 was compared to belt area CM of the marmoset. ► In both areas, responses to BPN were stronger and faster than responses to tones. ► BPN evoked responses at lower intensity and wider center frequencies than tones.
