Quantifying Physiological Response to Inadequate Sensory Feedback

, 2018
Electrodermal activity (EDA) and electrocardiograms (ECG) have been shown to be strong indicators of physiological stress responses [1]. However, we do not know if EDA and ECG can also be used to quantify physiological response to inadequate sensory ...

Blood–Brain Barrier Regulation: Evolving From Classic Strategies to Electrochemical Ion and Reactive Oxygen Species Control

Advanced Healthcare Materials, EarlyView.
Conventional therapies suffer from poor blood–brain barrier (BBB) penetration and disordered ion/reactive oxygen species (ROS) homeostasis, hindering precise neurological treatment. Electrochemical strategies achieve accurate spatiotemporal regulation of neural homeostasis.

A Principle of Nonlinear Feedback Action in Physiological Systems

IFAC Proceedings Volumes, 1968
Abstract The changes in excitability associated with local responses of excitable membranes are discussed, from the point of view of their effects on the autorhythmic activity of nervous elements. Particular attention is given to the state of hypoexcitability created by a local response, for the purpose of presenting a mechanism by which the rate of ...
