PMID-12665038[0] A system for MEA-based multisite stimulation.
-
- stimulate and record the same MEA channel.
- used voltage-control stimulation.
- very low leakage current switches, DG202CSE, 100Gohm, Maxim, above. non-mechanical = low vibration.
- switches switch between stimulator and preamp. obvious.
- uses active shorting post-stimulation to remove residual charge,
- uses active sample/hold of the preamplifier while the stimulator is connected to the electrodes.
- adds stimulation pulse to the initial electrode offset (interesting!)
