Neurofeedback Prototype with Electroencephalography for Stimulation and Control, Using the Alpha Wave

This document is the result of a research project called design and implementation of a prototype EEG Neurofeedback for control and stimulation of alpha wave, where, Neurofeedback is identifier as a therapeutic technique that was development by the Chicago University, to reduce conditions such as stress, insomnia, physical exhaustion, and hallucinogens dependence. In the design and implementation of real-time Neurofeedback, were used instrumentation amplifiers (INA 128), and low-pass active filters, aiming to detect the alpha wave; which is in low frequency ranges, for analog operation was also used, the TL 084 amplifier and FPGA card, the module pmodAD1 with 12 bits of resolution, and the visualization is presented in a 7 inch VGA screen with a resolution of 640x480 pixels, and for recording the EEG signal was used cup electrodes. The prototype (Neurofeedback) is distinguished by features such as: Easy, Integrated viewing screen, rechargeable batteries, feedback and binaural sound with low cost compared with commercial Neurofeedback, allowing reducing the effects of stress and many symptoms more.
