TL;DR: Testing the hypothesis of a shift in sensitivity from "transient" to "sustained" channels in the aging visual system failed to support the transient-shift hypothesis, and additional tests showed no age-related changes in temporal summation even within a single channel.

TL;DR: The simulations described in this paper provide insights into mechanisms of axonal excitation that can be carried out by following an easily understood protocol.

TL;DR: The present study assessed temporal summation of transient and sustained stimuli in the startle eyeblink response system in neonates during quiet sleep to suggest that the transient system is immature in infants, and that this immaturity is expressed differently by startle amplitude, probability, and latency.

TL;DR: Bath application of L-glutamate at concentrations higher than 1 × 10 4M suppressed excitatory postsynaptic potentials and evoked both a depolarisation and a reduction in the input resistance of the muscle fibre, compatible with the hypothesis that L- glutamate is an exciteatory transmitter at the neuromuscular junction.

TL;DR: Area summation functions derived for the steady-pedestal paradigm decreased as a power function of area, approaching an asymptote above one square degree, consistent with the classical data of threshold spatial summation.
