EEG reference – linked ears, summed ears, etc.

Reference corresponds to the VIN- connection on EEG amplifiers; on the MP3X, if using the SS1LA lead adapter, VIN- is on the lead adapter.

Use each ear as a reference for its own hemisphere—this will reduce ECG artifact

1. For each hemisphere, connect a lead from the VIN- on one of the amplifiers to the ear on that hemisphere.
2. Use jumper cables JUMP100C to connect this VIN- to the other amplifiers.
3. Connect a lead from the VIN+ of each of amplifier to the electrode locations on the hemisphere.

Link ears—use a CBL204 “Y” electrode lead adapter to link the left and right ears

1. Connect the two electrode leads into the two inputs of the “Y” adapter.
2. Connect the single output end of the “Y” to a jumper cable JUMP100C.
3. Use jumper cables JUMP100C to connect this VIN- to the other amplifier VIN- inputs.
