Figure 1: A set of 61 evoked excitatory post-synaptic potentials (EPSPs) Data in the left pane (a) describe the evoked voltage responses observed at the crayfish neuromuscular junction from 1000 stimulation trials. While the functions vary in height, width, and peak locations, all the functions have a similar underlying shape. The right pane (b) shows aligned firings with the estimated underlying shape g in red. These are the same data from (a) aligned to each other.
