... of 50–250 ms and inter-burst intervals of 2–24 s. Muscles expressed similar facilitation measured with paired stimuli except at the shortest inter-spike interval. However, distinct decay time constants resulted in differences in temporal summation. In response to bursting activity, augmentation occurred...

... not be demonstrated between pairs of fast-twitch cells or between mixed pairs of cells. Spike-like responses in both cell types exhibited non-synaptic facilitation in response to direct depolarizing stimulation. Both the maximum size and the initial rate of facilitation were frequency-dependent. Spike-like responses...

...R. R. Stewart; W. B. Adams; J. G. Nicholls ABSTRACT The role of presynaptic Ca 2+ entry in facilitation of transmitter release has been analysed by voltage-clamp measurements at synapses formed in culture by Retzius and P neurones isolated from the central nervous system (CNS) of the leech...

... suited to optimize the release process at the terminal by utilizing a frequency-facilitation mechanism and by minimizing a mechanism of fatigue in the release process. The different properties of oxytocin and vasopressin neurones are of important physiological significance. The secretory terminals...

...W. Rathmayer; M. Hammelsbeck ABSTRACT The superficial muscle fibres in the proximal head of the closer muscle in the crab Eriphia belong to four distinct fibre types (I-IV). By stimulating either the ‘slow’ or the ‘fast’ axon, facilitation properties of the EJPs were investigated in eight...

... alone also enhances muscle contraction and work, and results in greater depolarization. This latter effect appears to involve an accumulation of short-term facilitation, which becomes more acute as the time interval between the bursts is progressively shortened. In addition, contraction...
