Vision on the internationalization of physiology education: Trends and prospects / 生理学报

Rapid advancement of physiology education has occurred since the twentieth century due to the emergence of new pedagogies and collaborative effort of physiologists worldwide. Physiological organizations and institutions contribute to the teaching of physiology through international congresses, education symposia, teaching workshops, exchange programs, and journal publications. The Internet and information technologies play a crucial role in the promotion and improvement of computer-based physiology education across different countries. Interactive teaching practices and problem-based learning have also become globally applied strategies to enhance students' motivation and facilitate learning effectiveness. In this article, we review the global development and implementation of pedagogical approaches to the teaching of physiology, as well as the emerging trends and practices for physiology education in the future.

Development of neural correlates of linear motion in the rat vestibular nucleus / 生理学报

The capability of the central vestibular system in utilizing cues arising from the inner ear determines the ability of animals to acquire the sense of head orientations in the three-dimensional space and to shape postural movements. During development, neurons in the vestibular nucleus (VN) show significant changes in their electrophysiological properties. An age-dependent enhancement of membrane excitability is accompanied by a progressive increase in firing rate and discharge regularity. The coding of horizontal and vertical linear motions also exhibits developmental refinement in VN neurons. Further, modification of cell surface receptors, such as glutamate receptors, of developing VN neurons are well-orchestrated in the course of maturation, thereby regulating synaptic efficacy and spatial coding capacity of these neurons in local circuits. Taken together, these characteristic features of VN neurons contribute to developmental establishment of space-centered coordinates within the brain.

Neuronal plasticity of otolith-related vestibular system / 中国医学科学院学报

This review focuses on our effort in addressing the development and lesion-induced plasticity of the gravity sensing system. After severance of sensory input from one inner ear, there is a bilateral imbalance in response dynamics and spatial coding behavior between neuronal subpopulations on the two sides. These data provide the basis for deranged spatial coding and motor deficits accompanying unilateral labyrinthectomy. Recent studies have also confirmed that both glutamate receptors and neurotrophin receptors within the bilateral vestibular nuclei are implicated in the plasticity during vestibular compensation and development. Changes in plasticity not only provide insight into the formation of a spatial map and recovery of vestibular function but also on the design of drugs for therapeutic strategies applicable to infants or vestibular disorders such as vertigo and dizziness.
