“…MacPhee (1981) rightly pointed out that the identification of the fenestra cochleae on the face of the petrosal assumes that the secondary tympanic membrane lies across the cochlear aperture. In most eutherians, the membrane sits within the aperture, meaning that there is a fossula leading to the fenestra cochleae ( Bast and Anson 1952 ; Frick 1952 ; Anson and Bast 1953 ; Donaldson 1968 ; Jollie 1968 ; MacPhee 1981 ; Wible et al. 2009 ; Billet and Muizon 2013 ; Orliac and O’Leary 2016 ; Wible and Shelley 2020 ; Gheerbrant et al.…”

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.

“…The round window membrane is recessed within the confines of the round window niche, which is highly variable in its morphology 10–12 . According to Su et al, 11 the opening of the niche ranges between 0.48 and 2.7 mm in width, with a mean width of 1.66 mm.…”

“…The shape of the RWM is difficult to examine in human temporal bone specimens, because of its location deep in the fossula (round window niche), 1,2 parallel to the floor of the external ear canal. We were able to obtain a whole RWM specimen from a temporal bone without touching or grasping the membrane itself.…”
