Frank Guenther's research is aimed at uncovering the neural computations underlying the processing of speech by the human brain. He is the originator of the
Directions Into Velocities of Articulators (DIVA) model, which is currently the leading model of the neural computations underlying speech production. This model mathematically characterizes the computations performed by each brain region involved in speech production as well as the function of the interconnections between these regions. The model has been supported by a wide range of experimental tests of model predictions, including electromagnetic articulometry studies investigating speech movements, auditory perturbation studies involving modification of a speaker's feedback of his/her own speech in real time, and
functional magnetic resonance imaging studies of brain activity during speech, though some parts of the model remain to be experimentally verified. The DIVA model has been used to investigate the neural underpinnings of a number of communication disorders, including
stuttering apraxia of speech, and hearing-impaired speech. He has also made headlines for his research into non-invasive brain–computer interfaces for communication. In 2011, Guenther founded the
Unlock Project, a non-profit project aimed at providing free brain–computer interface technology to patients with locked-in syndrome. == Media ==
