Tubuloglomerular feedback: Its physiological and pathophysiological significance [PDF]
Kidney International, 1998 The mammalian nephron has a unique structure called juxtaglomerular apparatus (JGA); the primary function of the JGA includes tubuloglomerular feedback. Why is such a structure necessary? Analyses of available data strongly suggest that JGA has evolved to provide a fine tuning of the autoregulation of glomerular hemodynamics and high glomerular ...

Effects of Manipulating Physiological Feedback in Immersive Virtual Environments
Proceedings of the 2018 Annual Symposium on Computer-Human Interaction in Play, 2018 Virtual environments have been proven to be effective in evoking emotions. Earlier research has found that physiological data is a valid measurement of the emotional state of the user. Being able to see one’s physiological feedback in a virtual environment has proven to make the application more enjoyable.

On the Role of Negative Feedback in Physiological Systems
2025 IEEE 13th International Conference on Healthcare Informatics (ICHI)The study of physiological systems often involves the modeling of complex interactions and feedback mechanisms critical for maintaining homeostasis. This paper introduces a general dynamical model structure for multivariable physiological control systems, emphasizing intrinsic negative feedback.

A Physiological Feedback Controlled Exercise Video Game
, 2012 Purpose: This thesis presents a proof-of-concept for the use of physiological feedback in active video games to control the heart rate of players. Rationale: Physiological feedback controls can be used to increase or decrease the physical demands of an active video game presented to the user.

Feedback regulation of thyrotropin by thyroxine under physiological conditions
American Journal of Physiology-Endocrinology and Metabolism, 1981 We have studied the contribution of thyroxine (T4) itself to the feedback regulation of thyrotropin (TSH) secretion. Thyroidectomized rats received T4 replacement by one of two methods: 1) 5 or 10 micrograms T4 . 100 g-1 . day-1 in drinking water or 2) continuous subcutaneous infusion of 0.5, 1.0, or 2.0 micrograms T4 . 100 g-1 . day-1. Replacement of

Physiological Factors Related to Delayed Auditory Feedback and Stuttering: A Review
Perceptual and Motor Skills, 1982 Delayed auditory feedback (DAF) generally produces speech disturbances in normal speakers and improved fluency in stutterers. Several theorists have proposed that the speech disruptions of normal persons under such delayed feedback are an analog of stuttering. Related research has linked delayed auditory feedback and stuttering to several physiological

Time-delay signature suppression in delayed-feedback semiconductor lasers as a paradigm for feedback control in complex physiological networks [PDF]
Frontiers in Network PhysiologyPhysiological networks, as observed in the human organism, involve multi-component systems with feedback loops that contribute to self-regulation. Physiological phenomena accompanied by time-delay effects may lead to oscillatory and even chaotic dynamics

A Sensing Platform for Physiological and Contextual Feedback to Tennis Athletes [PDF]
2009 Sixth International Workshop on Wearable and Implantable Body Sensor Networks, 2009 In this paper we describe our work on creating a multimodal sensing platform for providing feedback to tennis coaches and players. The platform includes a fixed installation around a tennis court consisting of a video camera network and a localisation system as well as wearable sensing technology deployed to individual athletes. We describe the various

Predictive feedback control and Fitts' law [PDF]
, 2008 Fitts’ law is a well established empirical formula, known for encapsulating the “speed-accuracy trade-off”. For discrete, manual movements from a starting location to a target, Fitts’ law relates movement duration to the distance moved and target size ...
