Fixel-based analysis was used to probe age-related changes in white matter micro- and macrostructure of the corpus callosum between participants with (N = 54) and without (N = 50) autism spectrum disorder (ASD). Data were obtained from the Autism Brain Imaging Data Exchange-II (ABIDE-II). Compared to age-matched controls, young adolescents with…

Purpose: This study aimed to examine the activities of heart rate variability (HRV) and cortisol secretion as markers of the autonomous nervous system (ANS) and the hypothalamic-pituitary-adrenal axis (HPA) during the menstrual cycle in female athletes. Method: Saliva samples of the participants (n = 28) were collected successively at 0, 15, 30,…

Purpose: The significance of extended high-frequency (EHF) hearing (> 8 kHz) is not well understood so far. In this study, we aimed to understand the relationship between EHF hearing loss (EHFHL) and speech perception in noise (SPIN) and the associated physiological signatures using the speech-evoked frequency-following response (sFFR). Method:…

Menstruation is a global public health issue with negative discourses of shame, embarrassment, and disgust. There is growing anecdotal evidence linking negative menstruation experiences at school to absenteeism. This systematic review and line-of-argument synthesis aims to develop a conceptual understanding of menstruation experiences in schools…

Resting-state alpha brain rhythms provide a foundation for basic as well as higher-order brain processes. Research suggests atypical maturation of the peak frequency of resting-state alpha activity (= PAF) in autism spectrum disorder (ASD). The present study examined resting-state alpha activity in young school-aged children, obtaining…

Background: People with intellectual disabilities are at much higher risk of preventable deaths compared to the general community. However, studies identifying the cause of death in people with intellectual disability are generally based on one primary cause which is frequently attributed to the person's disability. Therefore, the aim of this…

NMDA receptors (NMDARs) and AMPA receptors (AMPARs) in amygdala nuclei and the dorsal hippocampus (dHipp) are critical for fear conditioning. Enhancements in synaptic AMPAR expression in amygdala nuclei and the dHipp are critical for fear conditioning, with some studies observing changes in AMPAR expression across many neurons in these brain…

This article details a 'puzzling' teaching and learning method to engage undergraduate nursing (BSN) and exercise sciences (BSES) students in physiology or medicine Nobel Prize-winning discoveries, while reviewing course material through the "Puzzling Physiology and Nobel Laureates" (PPNL) game. The qualitative evaluations of 117…

Urine formation in the nephron can be a very intimidating concept to students. This straightforward activity, performed by students during the nephron lecture, can help enforce the concepts as they uncover the structures and functions involved in urine formation.

Given the recently proposed three-filament theory of muscle contraction, we present a low-cost physical sarcomere model aimed at illustrating the role of titin in the production of active force in skeletal muscle. With inexpensive materials, it is possible to illustrate actin-myosin cross-bridge interactions between the thick and thin filaments…

The multidisciplinary nature of physiology requires students to acquire, retain, apply, and evaluate knowledge from different scientific disciplines. Optimal learning techniques, such as active learning, interleaving topics and conditions, and recall, can greatly enhance the speed and effectiveness with which students achieve this type of…

The complexity of modern societies necessitates that children learn highly abstract material, such as mathematics, which often conflicts with behavioral goals that are innately motivating. For instance, children's educational success is generally evaluated based on their individual achievements, while humans are motivated to learn by engaging in…

Undergraduate introductory human anatomy and human physiology courses are either taught as discipline-specific or integrated anatomy and physiology (A&P) sequences. An institution underwent a curricular revision to change the course approach from discipline-specific Human Anatomy and Human Physiology to an integrated A&P I and II sequence,…

The aim of this study was to investigate the effect of some sportive performance on the menstruation of female amateur volleyball players. 15 healthy female athletes with average age 20.0 ± 1.39 years, height average 165.93 ± 5.13 cm, body weight average 57.07 ± 4.42 kg and BMI (body mass index) 20.69 ± 4.78 kg/m2 , voluntarily participated in…

Climate change-related disasters have drawn increased attention to the impact of air pollution on health. 122 children ages 9-11 years old, M(SD) = 9.91(.56), participated. Levels of particulate matter (PM2.5) near participants' homes were obtained from the Environmental Protection Agency. Cytokines were assayed from 100 child serum samples: IL-6,…
