A New Lab for conducting Electrophysiology and Psychophysiology work has been established in 237 Rawl. We acquired a two chambered sound-booth from the Department of Communication Sciences and Disorders, as they moved into the new Allied Health Sciences Building, which came equipped with sound chambers. This sound-booth greatly enhances our ability to conduct physiological recordings by attenuating outside noise and distraction and creating a controlled-environment.

We have EEG systems, psychophysiology systems, and a variety of computers for data collection and analysis.

The lab is equipped with 2 Neuroscan NuAmps Electroencephalogram (EEG) systems for  recording brain electrical activity.
The new EEG systems have 40 channels. EEG measures brain activity by sensing small voltage changes related to neural activity using electrodes on the scalp. We have software for time and frequency domain analysis and for dipole source modeling.

The picture below shows a participant wearing an EEG “cap” containing the electrodes, which is connected to an amplifier and computer for data collection. The electrodes are prepared by injecting a conductive electrolyte and electrodes around the eyes are used for rejecting eyeblink artifact.

We also have a J&J I-330 C12+ pscyhophysiology system. This system has 12 channels for  several types of physiological recording. The electrocardiogram (ECG) records heart waveforms and the electromyogram (EMG) motor nerve activity. Other channels record respiration, temperature, and skin conductance. This system also has a two-channel EEG. Below is a computer screen shot of a researcher working with the software.
