Getting Acquainted with the Lab
The Colgate ERP Lab is housed within two electrically shielded rooms located in Olin Hall (Rooms 135 and 136). The lab consists of a Central Control Room and an Experiment Room. The Central Control Room contains three primary computers for running experiments and recording data from the EEG nets. One of the computers (the NetStation computer) is the primary interface with the net amplifier, the other two computers are experiment control station computers, and are used for creating and running experiments through either E-Prime or Psykinematix software. The two experiment control stations have different presentation capabilities. Consult the ERP lab coordinator for further details on selecting the station that is best suited to run your experiment.

From left to right: Shielded doorway between the Central Control Room and the Experiment Room. To the right of that is the NetStation computer and monitor (Mac). NetStation is the primary software used to communicate with the net amplifier and to save and process EEG data. It is also used to monitor real-time EEG wave forms during experiments. To the right of that is the E-Prime Experiment Control computer (PC) and monitor. E-prime consists of a software package that allows the experimenter to create and run an experiment. When running an E-Prime experiment, the E-Prime monitor is cloned onto the ViewPixx EEG experiment monitor in the Experiment room. To the right of that computer is the Psykinematix Experiment Control computer (Mac). It basically does the same thing as the E-Prime computer, but uses a different experimental software program (Psykinematx). When running a Psykinematix experiment, the Psykinematix monitor is cloned onto the ViewPixx EEG experiment monitor in the Experiment room.
Panoramic View of the Experiment Room
From left to right: Shielded doorway (for optional entrance from the hallway -- the Experiment Room can be accessed directly through a shielded doorway between the Central Control Room and the Experiment Room). To the right of the door is a cabinet for Geodesic HydroCel EEG net storage. Immediately adjacent to the net cabinet is the Net Preparation Station (for electrolyte soaking and disinfecting). To the far right, the Experiment Station. The participant sits in the white chair for the duration of the experiment, resting their chin on the black chin rest connected to the table. The white keypad is the device the participant uses to input information during the experiment. The silver and white box is the amplifier. The white arm attached to the table connects to the EEG net and allows for more maneuverability for the participant. The experiment monitor (ViewPixx EEG; blue) is the monitor that the participant views for the duration of the experiment. It is an LCD monitor that operates like a CRT monitor, and is driven by either the E-Prime or Psykinematix experiment computer located in the Central Control Room. The other monitor (further to the right and behind the net amplifier; black) is only used when checking EEG net electrode impedance. This monitor (which should be turned off during your experiment) is linked with the NetStation computer in the Central Control Room.
