Electrophysiology modalities:

electroencephalography (EEG) = brain

surface electromyography (sEMG) = muscles

electrocardiography (ECG/EKG) = heart

The idea is to create a community focused on active EXG experimentation. Meet regularly, design, execute, and analyze results from experiments, together. The purpose of this group is to create a small community of people interested in electrophysiology sensor-based self-experimentation. We have some research-grade sensors and equipment which we can use together. Please bring your sensors / systems as well. I have easy signal processing tools (Matlab) ready to use so that we can do analysis together as well, making it a complete process. Other methods and tools welcome. :) The idea is to informally ask questions and actively gather data, work on experiments, and complete analyses together.

I'm starting this because I have been self-experimenting with biohacking and lifehacking techniques using electrophysiology sensors (sEMG, EKG, EEG), and realized there is no in-person community built around actual data-gathering and experimentation with these kinds of sensors (i.e. "lets get together every week and measure our EEG, EKG, or sEMG data in some context that is interesting or relevant to us.)

How is this different than Quantified Self? At QS, people come together and share their experiences with self-tracking. Here, we don't talk about completed activity as much as help each other rapidly design, execute, and analyze the results of quick experiments (which can then later be shared with others, of course), and typically our experimental "n size" is greater than 1. So we are all about active groups designing and carrying out experiments together, vs individuals working with self-tracking.

Some ideas...

-> The other day Lily started talking to me about how Kundalini Yoga made her feel more mentally focused, and I suggested we test it by recording her EEG before and after an intensive day-long White Tantra meditation marathon.

-> A few months earlier, Nick and I experimented a bit with bench press to max while measuring sEMG to see what the muscle data looks like as the muscles get stronger over a few months.

-> Awhile back, I started comparing sEMG in the forearms and wrists while typing at different kinds of computer keyboards - can we quantify "ergonomic"? Can we determine which products are generally safer / require least muscle force to operate?

-> How do different breathing patterns (Pranayama) affect Heart Rate Variability (HRV) and Stress?

-> How does caffeine affect my ability to focus/concentrate, as measured through EEG? In-house sensor modalities include: sEMG, EKG / ECG, EEG (adhesive-based, 2ch max, not full-cap), Skin Conductance, Respiration (pressure strap), PPG, Pulse Oximeter, and of course... the accelerometers and gyros we all carry around with us (iPhones...)

Let's start experimenting!

I started the group because there wasn't any other type of group like this. I've met some great folks in the group who have become close friends and have also met some amazing business owners.
