Modeling the Extracellular Potential Generated by a Muscle Fiber as the Output Signal of a Convolutional System
Peer reviewed Peer reviewed
Direct linkDirect link
Javier Rodriguez-Falces – Advances in Physiology Education, 2024
A central topic in Bioelectricity is the generation of the extracellular potential that results from the propagation of a transmembrane action potential along the muscle fiber. However, the way in which the extracellular potential is determined by the propagating action potential is difficult to describe, conceptualize, and visualize. Moreover,…

Azpeleta, Clara; Santos, Pablo; Sobrado, Antonio; Lesmes, Marta; Gal, Beatriz – Advances in Physiology Education, 2021
Physiology is an integrative science that requires an understanding of the organism as a whole to acquire a deep comprehension of its functions and avoid misconceptions that may impair further learning. Thus it is necessary to develop resources that promote the integrative vision that Physiology requires. Chronobiology is a challenging discipline…

Teresa Zamalloa; Araitz Uskola; Ainara Achurra – Journal of Baltic Science Education, 2023
The human nutrition model is relevant in Biology education. Researchers and policymakers propose the introduction of modelling practices in science education, including the representation of the model. Despite being scarce, previous studies have shown that the guideline given to students conditions their performance when representing their models.…

Reinoso, Roberto; Delgado-Iglesias, Jaime – Journal of Baltic Science Education, 2020
Teachers' subject matter knowledge is a substantive component of the teaching-learning process. For a teacher to be able to transform and integrate into the classroom all the knowledge and experience they have acquired in the course of the professional activity, it is first necessary to acquire a deep and solid knowledge of the matter. The aim of…

Carpes – Advances in Physiology Education, 2024
Internationalization in higher education is essential, and although active learning methodologies are increasing and allow students to develop transversal skills, most still have a very local scope. In this context, the Collaborative Online International Learning (COIL) methodology is an interesting approach to benefit the students' development.…

A Novel Approach to Teach the Generation of Bioelectrical Potentials from a Descriptive and Quantitative Perspective
Peer reviewed Peer reviewed
Direct linkDirect link
Rodriguez-Falces, Javier – Advances in Physiology Education, 2013
In electrophysiology studies, it is becoming increasingly common to explain experimental observations using both descriptive methods and quantitative approaches. However, some electrophysiological phenomena, such as the generation of extracellular potentials that results from the propagation of the excitation source along the muscle fiber, are…

Assessing Photosynthesis by Fluorescence Imaging
Peer reviewed Peer reviewed
Direct linkDirect link
Saura, Pedro; Quiles, Maria Jose – Journal of Biological Education, 2011
This practical paper describes a novel fluorescence imaging experiment to study the three processes of photochemistry, fluorescence and thermal energy dissipation, which compete during the dissipation of excitation energy in photosynthesis. The technique represents a non-invasive tool for revealing and understanding the spatial heterogeneity in…
