What is Biofeedback? � Biofeedback = the technique of using monitoring devices to furnish information regarding an automatic bodily function, such as heart rate or blood pressure, in an attempt to gain some voluntary control over these functions[1].

Technology � (EEG) Electroencephalography is the recording of electrical activity along the scalp produced by the firing of neurons within the brain [2]. - Method of Detection: - Detects: Wave patterns (i. e. Delta, Theta, Alpha, Beta, Gamma and Mu) and Event Related Potentials (P 300, N 2 pc, and more)

Hardware Point of View � An example of a Two-channel EEG amplifier An example of an EEG device prototype

Commercial Product Emotiv EPOC Neuro. Sky Mind. Wave

Measuring Anxiety and Tension � Skin conductance, also known as galvanic skin response (GSR) is a method of measuring the electrical conductance of the skin, which varies with its moisture level. [3] � Heart Rate
