| Research Abstract |
Harmony is a kind of sounds whose components' frequencies are in relation of an integer ratio. Animals perceive the fundamental frequency (F0) which is the greatest common factor of harmonic sounds even if it does not exist. We observed mouse primary auditory cortex with two photon imaging and flavoprotein fluorescence imaging to investigate the neural mechanism to generate this phenomenon. As a result, it was revealed that the primary auditory cortex works as an associative memory circuit, and F0 is one of the components recalled by an associative memory circuit.
