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.

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.

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

Physiology and pathology of an immunoendocrine feedback loop
Immunology Today, 1988Abstract Research in autoimmunity has tended to focus on lymphocytes and their products at the expense of other factors that also contribute to the development of disease. Here, Guido Kroemer and colleagues stress that aberrations in immunoendocrinological communication may also be involved in autoaggression.

Physiological data feedback for application in distance education
Proceedings of the 2001 workshop on Perceptive user interfaces, 2001This paper describes initial experiments collecting physiological data from subjects performing computer tasks. A prototype realtime Emotion Mouse collected skin temperature, galvanic skin response (GSR), and heartbeat data. Possible applications to distance education, and a second-generation system are discussed.

The effect of visual feedback on physiological muscle tremor
Electroencephalography and Clinical Neurophysiology, 1974Abstract It has been reported that the availability of a visual monitor of force exerted during a voluntary constant contraction determines the presence or absence of a peak in the physiological tremor spectrum at 8–10 c/sec. This, together with other changes in the spectrum induced by added delays in the visual monitor system, has been taken to ...
