This document is intended to help you get started using the EPOC Flex. The EPOC Flex is a 32-channel, flexible EEG system. It was built on the award winning EPOC+ technology and is designed for researchers who would like to have a more flexible sensor placement and / or greater density of sensors. The reference sensors can be placed in any location on the cap, and on the ears with included earclips (gel sensors only ). EmotivPRO v1.4+ is required for operation.
