The short-latency DR-EPSPs resistant to Ca2+-lack and to addition of Mn2+ and Mg2+ result from electrical coupling between primary afferents and spinal motoneurons in frogs and toads. There are two time constants by which the time constant for the decay of the electrotonic DR-EPSP can be described: 1. the membrane time constant which determines the rate of passive decay of the membrane potential shift produced directly by the presynaptic spike, 2. the rate at which the presynaptic after… CONTINUE READING
