The School of Communication at Northwest University have developed a new audio test to help identify learning disabilities. Called BioMAP (Biological Marker of Auditory Processing) the technology has been licensed to Bio-logic Systems Corp.. According to the press release:
"The BioMAP is a robust and repeatable speech-evoked response that can reliably identify individuals with deficits in the timing of neural responses that cannot be revealed with other stimuli. Unlike conventional brainstem evoked response recordings using clicks or tones, the BioMAP uses speech syllables that better reflect the acoustic and phonetic complexities characteristic of speech. Using electrodes placed on the scalp, the BioMAP reflects neural activity produced by the auditory brainstem in response to speech. These neural events mimic the acoustic characteristics of the speech signal with remarkable fidelity."
