	You will want to bring a stimulus presentation computer (or use the CNI’s) as well as the laptop that runs NetStation. The EGI NetStation laptop should be kept on top of the amplifier in the mock scanner room. You will also need to use the peripheral gating monitor (please refer to the [[MR_Hardware#Physio_monitoring \| physio section]] on this wiki), which is permanently installed in the scanner suite on the desk next to the Linux computer. The EEG nets can be found either in the bathroom or in the mock scanner cabinet. There is a medium net (56-58 cm) and a large net (58-61 cm). For most people you will be using the medium net. There is also a small net in mock scanner cabinet.		You will want to bring a stimulus presentation computer (or use the CNI’s) as well as the laptop that runs NetStation.

			== Preparing to check electrode contact ==

			Plug the NetStation laptop into the Amplifier in the following way:

			*Firewire cable -> Firewire/Opt Converter -> short optical cable -> Amp Data I/O port

			These cables should be kept in the scanner suite desk on the far right next to the Linux machine.
