Reading the streamMEA, biochip, threshold, and activity terms
- MEA
- A multi-electrode array. This component shows 4 MEAs, 32 electrodes each.
- Biochip
- Each MEA is grouped into four logical 8-electrode biochips.
- Window
- Each pushed frame contains 4096 samples, roughly 1092.3 ms of raw voltage.
- Threshold
- Crossings are simple voltage threshold events. No unit identity is inferred.
- Center of activity
- A statistical average position weighted by crossing counts, not a biological region.
Mapping check: absolute 37 = MEA 2, local 05, biochip 0, electrode 5.
