WebLittle is known about ion channels that regulate the graded, subthreshold properties of nerve terminals. Using 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. WebFinally, I attempted to link the tonotopic specificity of this circuit to a specific aspect of auditory perception, frequency discrimination.In Chapter 2, I mapped the tonotopic …
