Physiology and pathology of an immunoendocrine feedback loop

Immunology Today, 1988
Abstract 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.

Emotional and physiological responses to false feedback.

Cortex; a journal devoted to the study of the nervous system and behavior, 2001
The relationship between autonomic-visceral arousal and emotional experience is unclear. The attribution or cognitive-arousal theory of emotional experience posits that emotional experience is dependent on both visceral-autonomic nervous system feedback and the cognitive interpretation of the stimulus that induced this visceral activation.

Force feedback teleoperation with physiological motion compensation

IFAC Proceedings Volumes, 2009
Abstract In medical and surgical robotized applications one of the most recurrent problems is the physiological motion of the patient. Specifically, respiratory motion can have a large amplitude and thus prevent accurate gestures. So, for a robot which interacts with a patient, it is obvious that being able to compensate physiological motion would be ...

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.

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.

The effect of visual feedback on physiological muscle tremor

Electroencephalography and Clinical Neurophysiology, 1974
Abstract 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 ...

Somatostatin in the physiologic feedback control of thyrotropin secretion

Life Sciences, 1976
Abstract The addition of an antiserum against Somatostatin (SRIF) to a culture of dispersed rat pituitary cells incubated in the presence of hypothalamic tissue enhances thyrotropin (TSH) secretion into the medium. This indicates that SRIF is normally secreted in amounts sufficient to affect TSH secretion and suggests that SRIF may be the agent ...

Feedback from Physiological Sensors in the Classroom

2015
The 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.

Physiological data feedback for application in distance education

Proceedings of the 2001 workshop on Perceptive user interfaces, 2001
This 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.

Coaching robot behavior using continuous physiological affective feedback

2011 11th IEEE-RAS International Conference on Humanoid Robots, 2011
In this work we present a new way for human-robot interaction, where a robot is able to receive physiological affective feedback for its actions from a human trainer and learn from it. We capture the human trainer's facial expressions using a wearable device that records distal electromyographic signals and uses computational methods of signal ...
