Auditory Brain Stem Evoked Responses to Bone-Conducted Signals

Exaggerated anticipatory anxiety is common in social anxiety disorder (SAD). Neuroimaging studies have revealed altered neural activity in response to social stimuli in SAD, but fewer studies have examined neural activity during anticipation of feared social stimuli in SAD. The current study examined the time course and magnitude of activity in threat processing brain regions during speech anticipation in socially anxious individuals and healthy controls (HC). Method Participants (SAD n = 58; HC n = 16) underwent functional magnetic resonance imaging (fMRI) during which they completed a 90s control anticipation task and 90s speech anticipation task.

“…Another candidate for the early signal would be bone conduction versus air conduction. However, bone conduction has been reported with longer, not shorter, latencies than air conduction, and thus, yields no explanation for the short latency of the first component [31], [32]. Artifacts caused by laser light interactions with the electrode could be ruled out since the signal disappeared ~4 min postmortem in the euthanized animal.…”

“…x Two case reports are included to illustrate the management of early investigation for hearing loss and infants, and only sporadic reports that discuss the BC-ABR in the presence of conductive HL in infants or adults are documented. 23,34 Despite the aforementioned limitations, considerable evidence suggests that bone conduction ABR testing can make important contributions to the assessment of hearing in infants. Furthermore, modi cations of test protocols can minimize some of these technical limitations allowing BC-ABR to be used as an additional tool in the differential diagnosis between conductive and sensorineural hearing.…”
