Abstract :
We studied the dependence of response property of the syncytium consisting of receptor cells on dynamics of collective ion channel gating in the cells, which are periodic, stably chaotic, and unstably chaotic. The dynamics of unstable chaos state synchronizes the potential variation of all receptor cells in the syncytium induced by external stimuli. The syncytium system in the stable and unstable chaos states can detect a weak periodic input signal without assistance of any level of noise
