“…In the present study, we confirmed findings of the past studies 1–4 that each item of measurement pertaining to auricular size continuously and significantly increased after reaching adulthood until advanced age. The rapid expansion until the age of 15 is that of maturation or development, whereas the subsequent slow extension is considered change with aging.…”

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.

“…He concluded that inclusive size of the external ear varies according to the ethnic groups. [2] All above mentioned study and researches had a close match with our findings which clearly signifies that male ears increases in all the parameters in comparison to that of females. Azaria R et al included a total of 547 subjects with healthy ear morphology.…”

“…Numerous studies have demonstrated a gradual, linear increase in ear length after maturation across various populations. 6,8,14 Our findings corroborate this observation, revealing a significant linear relationship between age and ear length. However, the coefficient for Tibetan individuals was unexpectedly low.…”
