Quantal Release Statistics: 2D Synapse Model

This 2D counterpart strips the neuromuscular junction down to its core statistics: a fixed grid of N release sites, each an independent coin flip with probability p on every trial. Firing a trial genuinely runs N separate Bernoulli draws, sums the released quanta into an end-plate-potential amplitude, and animates the fusing sites and released transmitter live. Run many trials and the running histogram builds the classic multi-peaked quantal distribution in real time — while a live quantal-analysis panel recovers the true N and p purely from the mean and variance of the trials, exactly as del Castillo and Katz first inferred synaptic quantal content from statistics alone.
