Dr. Randall Benson speaks with editor Amy Zellmer of The Brain Health Magazine and host of “Faces of TBI Online Radio” about how to take the mystery out of TBI through research. It is a podcast dedicated to traumatic brain injury (TBI) awareness. Created by survivors for survivors. They interview survivors, caregivers, medical professionals, andRead More

Phonetic processing areas revealed by sinewave speech and acoustically similar non-speech
The neural substrates underlying speech perception are still not well understood. Previously, we found dissociation of speech and nonspeech processing at the earliest cortical level (AI), using speech and nonspeech complexity dimensions. Acoustic differences between speech and nonspeech stimuli in imaging studies, however, confound the search for linguistic– phonetic regions. Presently, we used sinewave speech (SWsp) and nonspeech (SWnon), which replaceRead More
Parametrically Dissociating Speech and Nonspeech Perception in the Brain Using fMRI
Candidate brain regions constituting a neural network for preattentive phonetic perception were identified with fMRI and multivariate multiple regression of imaging data. Stimuli contrasted along speech/nonspeech, acoustic, or phonetic complexity (three levels each) and natural/synthetic dimensions. Seven distributed brain regions’ activity correlated with speech and speech complexity dimensions, including five left-sided foci [posterior superior temporal gyrus (STG), angular gyrus, ventralRead More
