Electrical stimulator
From SpinozaWiki
For electrical current stimulation, we use a Digitimer Constant Current Stimulator, model DS7A. It can be used at 3T, 7T, as well as the mock scanner.
Most important specifications:
- MDD CE certified and FDA cleared medical device
- Pulse durations from 50µs to 2ms (DS7A) and 50µs to 200µs (DS7AH)
- 100mA (DS7A) constant current output from 400V
- Flexible TTL compatible trigger options or front panel push button
- Alternating Polarity control – a toggle switch allows the stimulator to operate in +ve, -ve or alternating polarities during stimulation
