Extended Data Fig. 2: Example recording performances of type-II (A) and –III (B) NET electrode designs.

These two designs offer high electrode density that allows for the recording of individual neurons by multiple channels and therefore perform better in single unit isolation. Color code corresponds to the location of the recording sites. Each dashed box outlines the waveforms of a single unit recorded on the corresponding sites. Scale bars: 100 μV (vertical) and 2 ms (horizontal).
