Abstract

Alcohol consumption is known to associate with several diseases, injuries, and social problems. The long-term, excessive alcohol exposure can lead to liver cirrhosis and pancreatitis. After repating alcohol exposure, alcohol dependence would develop an individually behavioral, cognitive, and physiological phenomenon. Previous studies indicated that although the left hemisphere was selectively employed for processing linguistic information irrespectively of acoustic cues or subtype of phonological unit, the right hemisphere was employed for prosody-specific cues. These previous studies provided the impetus for future investigations of tone perception and temporal integration differences in tonal brain speaker who had long-term, excessive alcohol exposure such as Thai in the present study. The present study used both an auditory mismatch negativity (MMN) component of event-related potentials (ERPs) recording and the standardized Low-resolution Electromagnetic Tomography (sLORETA) techniques to measure the degree of cortical activation and to localize the brain area contributing to the scalp recorded auditory MMN component during the passive oddball paradigm. Ten healthy right-handed adults participated in this study. The findings showed that both [kha:] - mid tone perception and [khá:] - high tone perception elicited a strong MMN between 215-284 ms with reference to the standard-stimulus ERPs. Source localization was obtained in the middle temporal gyrus of the right hemisphere for both [kha:] - mid tone perception and [khá:] - high tone perception. Automatic detection of tone perception in alcoholic tonal brain is a useful index of language universal auditory memory traces.

Abstract

Aging affects facial tissues, including skin, fat, muscles, and bones, with the temporal region playing a crucial role in both function and appearance. Temporal depression contributes to an aged look, increasing demand for aesthetic procedures. However, the complex layered structure and vascular pathways present challenges for safe interventions in this region. This study utilized high-frequency ultrasound to map the depth and position of the deep temporal arteries and assess the anatomy of the temporal region in Thai individuals aged 25–50 years. The observational cross-sectional design included 33 participants (15.15% male, 84.85% female) with an average age of 33.42 years. High-frequency ultrasound was used to evaluate the soft tissue and artery positioning. The sample included 10 individuals with and 23 individuals without hyaluronic acid filler injections. Significant differences in skin thickness, subcutaneous layers, SMAS layers, temporalis muscle thickness, and temporal bone characteristics were observed between the two groups. Filler injections notably altered anatomical structures, affecting artery depth and position. Despite limitations in sample size and population specificity, the findings underscore the importance of detailed anatomical knowledge for safer and more effective injectable procedures. Ultrasound imaging serves as a healthcare tool in guiding aesthetic interventions in the temporal region.
