Close neighbor spiking neurons in mucus-stimulated ganglia fall in and out of synchronization. Sample traces showing spike activity recorded simultaneously from two different electrodes from a Euglandina ganglia stimulated by mucus applied to lip extension. Traces labeled a, b, and c are 4 second expanded samples of the regions under the bars in the top panel. Bottom Panel: Image of Euglandina snail ganglia on electrode array with displayed electrodes identified with arrows. Colors correspond to the particular electrode trace shown.
