From the population average to the raw voltage

This starts with the figure everyone publishes — the average PSTH across all neurons, one trace per stimulus — and lets you click your way down to the data it was computed from.

1. click a trace
2. click a neuron's row
3. click a trial row
4. you are looking at voltage

normalize each TRIAL before averaging trials normalize each NEURON before averaging neurons average with

Try divide by baseline on the TRIAL selector, then move it to the NEURON selector instead. Per neuron the peak is a sane ~3.9× over a baseline of 1. Per trial it jumps to ~6.2× and the whole post-stimulus period floats near 1.8 — because each denominator is a baseline estimated from a couple of spikes. Averaging ratios with noisy denominators biases the answer upward.
