EEG Lab Supervisor:
Alana Campbell, Ph.D.
EEG Lab Manager:
Mae Nicopolis, B.S.
The mission of the CIDD Electrophysiology Research Lab is to provide personnel and research affiliates with access to cutting edge electrophysiology equipment, as well as a place to run experiments. Services range from assisting researchers with the design aspect of experiments, to the creation and delivery of stimuli for electrophysiology studies, to training investigators as well as their assistants on equipment application, data recording, artifact removal, and data analysis.
Consultation regarding the advantages and disadvantages of different ERP analysis methods is offered. Additionally, the development of new methods for EEG/ERP analysis is provided.

Equipment and Software
Equipment at site 1
Location: 101 Manning Dr. Medical Wing D, Room 383, Chapel Hill
- One Electrical Geodesic Dense Array EEG Net Amplifier 300
This system allows for high-density EEG measurement up to 256 channels with a minimum of preparation time and without the need for skin preparation, hence, the usual, unpleasant scratching of the scalp after the electrode paste is applied can be omitted. These attributes make it a perfect choice for high density EEG in infant/pediatric populations.
- Four 128-Channel HydroCel Geodesic Sensor Nets (37-38cm, 44-47cm, 47-51cm, 51-54cm)
The HydroCel Geodesic Sensor net's elastic tension structure and electrolyte based application allows for quick application with a 15 minute set-up. The unique soft pedestal design of the HydroCel Skin Interface Chamber creates a sealed microenvironment, hydrating the skin and creating an interface between the skin and electrode. The HydroCel Geodesic Sensor Net's guarantees complete head coverage with attention to both appropriate inter-sensor distance and coverage of the underside of the head. The small inter-sensor distances translate to a more accurate measurement of the voltage field and coverage under the head allows for more accurate dipole source reconstruction.

- One NeuroScan SynAmps RT Amplifier system
SynAmps RT is a 70 channel amplifier system, consisting of 64 monopolar, 4 bipolar, and 2 high-level input channels (for receiving voltage outputs from other equipment). Each channel has a dedicated 24 bit A-to-D converter, to ensure the most accurate sampling available. SynAmps RT is a DC amplifier, allowing the recording of slow potentials without high pass filtering. Sampling rate can be up to 20,000Hz (synchronized across all channels) which allows for recording of the fastest activity such as ABRs (maximum low pass filter is 3500Hz).
