CSF signaling in physiology and behavior

2000
Publisher Summary Cerebrospinal fluid (CSF) has traditionally been considered as a drainage system for the brain. Recent work provides compelling evidence that the CSF provides a route of communication for signals. There are several aspects of existing evidence for CSF signaling that are particularly impressive.

AKT Signaling in Physiology and Disease

2010
The serine/threonine kinase AKT functions as a critical mediator of signaling downstream of PI3 kinase. Studies over the last two decades have firmly established the importance of AKT in the regulation of cell survival, proliferation, and insulin-dependent metabolic cell responses.

Physiological Foundations of Neural Signals

2013
One of the central goals in neuroscience is to understand the function of neural circuits in the brain and how they are related to behavior. As a result, a great effort has been dedicated to developing techniques which enable the recording of the brain’s electrical activity at different spatial scales.

Active Sensors for the Acquisition of Physiological Signals

2018 IEEE SENSORS, 2018
The acquisition of physiological signals from human subjects has been an important research area for quite some time. Common issues involved in standard schemes for acquisition and processing of physiological signals, such as the possibility of the electrodes being easily damaged, or the probability of irritation upon prolonged usage, necessitate the ...

Analysis of Physiological Signals

1978
In this chapter we discuss briefly the nature of signals encountered in physiological systems and some of the analytical tools used to study them. We avail ourselves of this opportunity to present the mathematical preliminaries necessary for the development of the methodology of functional identification of systems (primarily the white-noise approach ...

Physiological Signal Processing

1997
Several clinical situations lend themselves to the repetitive, closely grouped measurement of physiological parameters. These include recording electrical signals and measuring pressures, frequencies, volumes, flows, or temperatures. In general, physiological signals vary continuously over time.

Discrete Signal Processing for Physiological Signals

2019
Digital signal processing is widely used in a variety of applications from telecommunications and medical diagnostics to entertainment and recreation. The mathematics of such digital signal processing is the same in all these areas. In this chapter we take a broad overview of some of the fundamental techniques in digital signal processing, like optimal

Using physiological signals for emotion recognition

2013 6th International Conference on Human System Interactions (HSI), 2013
Recognizing user's emotions is the promising area of research in a field of human-computer interaction. It is possible to recognize emotions using facial expression, audio signals, body poses, gestures etc. but physiological signals are very useful in this field because they are spontaneous and not controllable.
