BACKGROUND & OBJECTIVES Regular practice of slow breathing has been shown to improve cardiovascular and respiratory functions and to decrease the effects of stress. This pilot study was planned to evaluate the short term effects of pranayama on cardiovascular functions, pulmonary functions and galvanic skin resistance (GSR) which mirrors sympathetic tone, and to evaluate the changes that appear...

OBJECTIVES The objective of this study was to study the effects of meditation on stress-induced changes in cognitive functions. METHODS The study was conducted on 32 healthy adult male student volunteers who had never practiced meditation before the study. The study consisted of practicing 20 minutes of guided meditation and administration of psychologic stress to the subjects. The psychologi...

There are numerous studies which suggest that perhaps music is truly the language of emotions. Music seems to have an almost willful, evasive quality, defying simple explanation, and indeed requires deeper neurophysiological investigations to gain a better understanding. The current study makes an attempt in that direction to explore the effect of context on music perception. To investigate the...

In recent papers Caldwell, Bibby and Brown (2002, 2003) (hereafter referred to as CBB) have introduced a new and elegant method for analysing magnetotelluric (MT) data which can be applied directly to galvanically distorted data in a regional conductivity structure of any dimension. It is therefore more general and direct than previous methods (e.g. Bahr, 1988; Groom and Bailey, 1989; Smith, 19...

The renewable energy sources such as PV modules, fuel cells or energy storage devices such as super capacitors or batteries deliver output voltage at the range of around 12 to 70 VDC. In order to connect them to the grid the voltage level should be adjusted according to the electrical network standards in the countries. First of all the voltage should be stepped up to sufficient level at which ...

This work aims to verify whether Galvanic Skin Response (GSR) can be used as a valid pain indicator and to analyze the changes in GSR during hypnotic analgesic condition. Two types of experiments were conducted namely ‘Pain-GSR’ (PG) and ‘Hypnosis-Pain-GSR’ (HPG) experiments for 10 subjects. The experiments were done under pain and no-pain conditions on subjects of both the gender in the age gr...

Sometimes, one needs to control different emotional situations which can lead the person suffering them to dangerous situations, in both the medium and short term. There are studies which indicate that stress increases the risk of cardiac problems. In this study we have designed and built a stress sensor based on Galvanic Skin Response (GSR), and controlled by ZigBee. In order to check the devi...

Affective reasoning holds significant potential for intelligent tutoring systems. Incorporating affective reasoning into pedagogical decision-making capabilities could enable learning environments to create customized experiences that are dynamically tailored to individual students’ ever changing levels of engagement, interest, motivation, and self-efficacy. Because physiological responses are ...
