Intelligent Physiological Monitoring and Feedback System for Driver Safety
2011 Fifth International Conference on Genetic and Evolutionary Computing, 2011In the course of driving, sudden disease outbreak often cause serious traffic accidents. If drivers can real-time understand their physiological state, and then they could have a chance to get the best solution at the first time. Maybe accidents will be largely reduced.

Feedback regulation of thyrotropin by thyroxine under physiological conditions
American Journal of Physiology-Endocrinology and Metabolism, 1981We 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 Significance of the Negative Short-Loop Feedback of Prolactin
Neuroendocrinology, 2008The aim of the present study was to evaluate the physiological significance of the rapid, short-loop, negative feedback of prolactin by passive immunization with antiserum to rat prolactin injected into the third cerebral ventricle (3 V) of conscious, freely moving intact or castrated male rats.

Feedback from Physiological Sensors in the Classroom
2015The Bill and Melinda Gates Foundation recently announced the development of an “engagement pedometer” that can identify exciting or boring moments to be used in classrooms. Researchers at the University of Hawaii have also developed potential real-time cognitive load indicators that also could be used in the classroom.

Unresponsiveness of the endorphinergic system to its physiological feedback in obesity
Appetite, 1991Beta-endorphin (beta-Ep) plasma levels are higher in obese patients than in normal subjects. To establish that this finding constitutes hyperendorphinemia, 28 obese patients aged 12-55 years, six males and 22 females, (weighing 61-117 kg) were investigated twice by an overnight 1-mg p.o. dose dexamethasone suppression test (DST) before and after weight

The Impact of System Feedback on Learners’ Affective and Physiological States
2010We investigate how positive, neutral and negative feedback responses from an Intelligent Tutoring System (ITS) influences learners' affect and physiology. AutoTutor, an ITS with conversational dialogues, was used by learners (n=16) while their physiological signals (heart signal, facial muscle signal and skin conductivity) were recorded.

Proportional Control of Negative Feedback Physiological Systems
Understanding the dynamics of negative feedback physiological control systems is fundamental for assessing their stability and properties in healthy and diseased states. In this study, we aim to define a system-theoretic general mathematical framework to investigate the dynamics of physiological control systems that are supported by an external ...Granata, Rita +8 more

Periodic Diseases, Physiological Rhythms and Feedback Control—A Hypothesis
Australasian Annals of Medicine, 1970SummaryConsideration of some general features of controlled biological systems and examination of a particular system, granulo‐poiesis, suggest that feedback control may be responsible for many physiological rhythms and for the periodic features observed in a number of diseases.

The Bulletin of Mathematical Biophysics, 1959
In the human, the antagonistic, extensor-flexor system of the leg is an example of a common type of neurophysiological feedback system. After a brief introduction to the neuroanatomy and physiology of this feedback system, the paper formulates transfer functions from temporal response data available in the literature.

Mechanoelectric Transduction/Feedback: Physiology and Pathophysiology
2007Cardiac “mechanotransduction” involves various physiological and biophysical phenomena in which mechanical energy is transduced to changes in function of cardiac myocytes and of the whole heart. In this chapter different manifestations of mechanotransduction are reviewed, with special emphasis on the “mechano-electric” feedback aspect.
