HEGStudio
HEGStudio is a program for performing HEG neurofeedback. HEGStudio is simple, easy to use, and free/open source. It was written by Jonathan Toomim of HEG Research.
HEGStudio requires an HEG system to operate. Currently, it supports the nIR HEG Peanut from HEG Research as well as the Pocket A1/A2/A3 and the nIR HEG Pendant from Pocket Neurobics. HEGStudio runs on Windows XP/Vista/7/8 as well as Mac OS X.
