Infrastructure

 

The Cognition, Brain, & Language Lab encompasses approximately 320 square feet of space in the Malicky Center. The front collaborative space is designated for training, storage, data processing/analysis, and electrode net sterilization. The testing suite is separated from the collaborative space into two smaller rooms, bisected by a 34”x34" window for participant observation. In the Participant room, subjects sit in front of a computer monitor and complete cognitive and psycholinguistic tasks while we record their EEG. In the Researcher room immediately behind the participant, researchers load the stimulus presentation sequences and visually inspect the EEG data during acquisition. A speaker was mounted above the window in Room C for auditory stimulus presentation.The two-room set up is well-suited for observing data collection and also training research assistants. 

 

EEG/ERP Equipment

 

  • Six HydroCel Geodesic 256 electrode-channel nets (MagStim-EGI) to fit adult head sizes

  • Three HydroCel Geodesic 128 electrode-channel nets (MagStim-EGI) to fit pediatric head sizes

  • Two EGI Net Amps 300 series amplifier and analog-to-digital converter

  • Net Station 5.4 EEG acquisition licenses with Geosource 3.0 source localization add-ins

  • E-prime 2.0 stimulus presentation licenses

  • Mac (MacOS) computers for EEG acquisition, processing and analysis

In the lab we have five 256-electrode EEG nets with the additional three 128-electrode EEG nets

For more information on our lab’s infrastructure and equipment, please see our recent publication in the Journal for Undergraduate Neuroscience Education

Training
IMG_7789.jpg

All student research assistants are trained in electrode net application and EEG acquisition. Face shields, masks, and gloves are worn during application.

Two student researchers together coordinate the data collection session. While one directly instructs the participant, the other is here managing the EEG acquisition and stimulus presentation programs.

Faculty or students interested in training in EEG are encouraged to contact Dr. Ledwidge directly for information on upcoming workshops.
