ref: Jimbo-2003.02 tags: MEA microstimulation artifact supression date: 12-17-2011 01:41 gmt revision:2 [1] [0] [head]

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!)
