Facilities

Auditory Electrophysiology

The facilities house equipment for multi-channel auditory evoked/event-related potential recordings and corresponding brain mapping software, including 4- and 16-channel systems from TDT, three 2-channel systems from Intelligent Hearing Systems, and three 64-channel EEG systems from Advanced Neuro Technology (ANT Neuro). We use a Polhemus FastTrack to better estimate electrode position. The laboratory also has access to a Functional Near-Infrared Spectrometry (fNIRS) system by Imagent featuring 64 emitters and eight detectors for recording neural metabolic activity with the temporal resolution of ERPs while identifying the intra-cranial sources with millimeter precision.

These systems include a custom MATLAB-based software suite for stimulus generation, presentation, hardware triggering, and simultaneous behavioral response collection. We also have an extensive set of image processing software for data analysis and interpretation including asalabTM and asaTM from ANT-Neuro as well as MATLAB-based BrainStorm and EEG-Lab.
