Brain Challenge Events in Explorations of Neuroscience for Consumers

The last 4 years of IEEE Brain exploratory events in the form of hackathon, challenge or competition, regarding brain signal datasets have covered brain computer interface and brain data bank processing incorporating neural network /AI modeling. These exploratory efforts are analyzed from investigations of individual EEG profiles, multi-user and multi-modal physiological signal interactions. Some advancements are destined for IoT, to benefit consumers.
