... hair cell mechanoreception postsynaptic potential Superfusion with 50 mmol l –1 sodium glutamate in ASW caused a reversible tonic depolarization of the nematocytes of 9±3 mV within 5 min ( Fig. 8A ). Simultaneously, the amplitudes of superimposed L- and T-potentials decreased from 42±5 mV...

... periods without decrement. In contrast, inhibitory postsynaptic potentials (IPSPs) never last for more than 15–35 ms. This paper examines mechanisms which could limit the duration of these IPSPs. An IPSP begins 4-5 ms after a presynaptic neurone starts to depolarize from its resting potential...
