To develop and evaluate a probabilistic model of auditory receptor transduction linking hair cell transmitter release to auditory neuron EPSPs and firing patterns.
Formulated a probabilistic mathematical model incorporating stimulus-dependent transmitter release fractions, transmitter reuptake into the cell, and cleft clearance.
Simulated mammalian auditory nerve discharge patterns, rate-intensity functions, interval/period histograms, and incremental adaptation responses.
Modeled and compared EPSP amplitude adaptation against empirical afferent neuron data from the goldfish sacculus.
Accurately reproduced mammalian rate-intensity functions, discharge interval and period histograms, and incremental auditory responses without requiring multiple discrete release sites.
Replicated the adaptation dynamics of successive EPSP amplitudes observed in the afferent neurons of the goldfish sacculus, indicating that transmitter reuptake and variable release fractions account for synaptic adaptation.
