Extracellular recording of dissociated leech neurons mechanically placed on top of coaxial sensing region of a cNEA. (A) Schematic of ganglion sac placement onto an individual sensing region within the device. (B) Spontaneous bursts during 60 s recording. Scale bars: 400 μV/10 s (C) One waveform type found within burst. (D) Second waveform resembling extracellular action potential found during post-recording spike sorting analysis. (E,F) Closer looks at two distinct waveforms extracted during post-analysis spike sorting. Scale bars, upper right: 50 μV/10 ms, lower right: 200 μV/3 ms.
