WebUsing the calyx of Held, we demonstrate here a large presynaptic persistent Na(+) current with unusually hyperpolarized activation voltage. This feature allowed the current to determine both the resting potential and resting conductance of the nerve terminal. Calyces express presynaptic glycine receptors whose activation depolarizes the synapse. WebTraditionally, the calyx of Held synapse is viewed as a highly reliable relay in the sound localization circuit of the auditory brainstem, with every presynaptic action potential triggering a postsynaptic action potential in vivo. However, this view is at odds with slice recordings that report large short-term depression (STD). WebJan 13, 2024 · The Calyx of Held Synapse: A Model Synapse Suitable for Investigating Presynaptic Mechanisms. The calyx of Held is the largest nerve terminal in the mammalian central nervous system, occupying 25–50% of the postsynaptic cell body, located in the medial nucleus of the trapezoid body (MNTB) within the superior olivary complex .
