Calyx of Held nervous system has allowed for direct research within a mammalian model and the large size increases the ease of electrophysiological recording. For these reasons it has been popular in understanding transmitter release. Specifically, the calyx of Held is used because of: Calyx of Held The Calyx of Held is a particularly large synapse in the mammalian auditory central nervous system, so named by Hans Held in his 1893 article "Die centrale Gehörleitung" because of its resemblance to the calyx of a flower.
