Recording and online analysis of auditory steady state responses (ASSR) in Matlab.
Auditory steady state responses (ASSR) are a current research focus because of their potential use as a diagnostic tool. Research platforms are required to test user defined stimuli and algorithms for the analysis of electrophysiologic responses. Commercially available ASSR devices are not adequately flexible. To enable a larger group of scientists to pursue ASSR research, we introduce a cost-efficient and flexible ASSR setup. ASSR recording and online analysis software in Matlab (The Mathworks, Inc.) was developed for a standard PC equipped with an external professional sound card, audiometric headphones, and an EEG biosignal preamplifier.
