Subject Preparation: Tactile Stimulation

The MEG Core has two types of tactile stimulators: the airpuff stimulator and the Galileo system.

Airpuff Stimulator

Directions:

In MSR:
- Attach airpuff device to channel 1,2, or 3 with medical tape.
- Place on subject’s finger to demonstrate pressure and press the corresponding valve (1,2, or 3) on the airpuff box.
- Remove and replace after the subject is situated in the helmet. (They will need their hands to hold the headpads in place.)
In Lab:
- Connect Airpuff channel to ADC cable 1 or 4 at the airpuff box with a t-connector.
At the ADC box:
- Connect the ADC cable (corresponding to the number you used above, 1 or 4) to D0 with a t-connector and attach a short BNC cable to channel 1 on the DSQ 3500 Electronics Control Console.

Note: ADC001 is the expected input for the HV Protocol. Your script may use ADC002. Be sure to confirm which input is expected by your scripts.

Instructions to be updated.
