Biosensors And You
- 1. BIOSENSORS AND YOU! JEAN RINTOUL
- 2. ADDING SENSORS GIVES US SHORTER AND BETTER FEEDBACK LOOPS We improve, by making mistakes, realizing what went wrong, so that we can do it better next time.
- 3. Past: Complex, expensive, detailed, regulated, small scale, inaccessible Now => Future: Simple, cheap, unregulated(no FDA approval), mass consumer scale, democratized Cost versus function?
- 6. NEUROFEEDBACK Train yourself to focus attention, and ignore distraction.
- 7. BRAIN TRAINING- READ THE COLOR OF THE INK AS FAST AS POSSIBLE
- 8. NOOTROPICS
- 10. LOTS OF POWERFUL INFORMATION… • Blood pressure through blood velocity • Blood alcohol • Circadian rhythms, slow wave sleep • Respiratory rate • Allergy monitoring • Correlations to location, local plants, diet, weight, blood nutrients, DNA sequencing etc especially when you add in the data streeams coming from 23 and me, sano intelligence and other health sensors. • Heart beat • Arrhythmia • Stress(heart rate variability)/GSR • temperature variations with stress or fever • EMG (muscle activity) • Movement/steps/calorific burn

- 12. THE AUTONOMIC NERVOUS SYSTEM “Rest / Digest” “Fight / Flight” d (and the “brain” is distributed throughout your body)
- 13. THE BODY IS THE GATEWAY TO THE BRAIN (AND THE “BRAIN” IS DISTRIBUTED THROUGHOUT YOUR BODY) Autonomic nervous system: rest and digest (parasympathetic nervous system) vs fight or flight (sympathetic nervous system). The wandering nerve-the vagus nerve sends information from the body, back to the brain.
- 14. EXAMPLE OF THE DISTRIBUTED BRAIN Brain: 100 billion neurons Stomach: 1/1000th the number of neurons in the brain Spinal chord: 1/100th the number of neurons in the brain Heart: 40 000 neurons The Brain-Gut Connection – The Enteric Nervous System: Why do we get butterflies in our stomach before a performance? Why does indigestion produce nightmares? Why are antidepressants now also being used for gastrointestinal ailments?
- 18. WOULD YOU DO THIS TO YOURSELF?
- 19. Thanks!
Notes de l'éditeur
- bio-hacking, bio-tracking? Why? Because we don’t understand ourselves. You could work on astronomy and space - but it seems like we could get further faster by looking at the problems we experience everyday – sickness, sleep deprivation, caffeine addiction, and stress… if we can optimize these problems, it seems that colonizing other planets, will be much easier… (y’know, if that’s what you want to do, otherwise, just hanging out here on earth will be much more pleasant) Become more aware so we can make better decisions The question is where to start with bio-hacking – with the brain? The seat of the intellect, or the body? I think the body has been overlooked, and let me tell you why.
- It’s better to make small mistakes frequently, than very large ones occasionally. If the mistake is not terminal, we can just adjust our path continuously based on the sensor feedback so that we are generally headed in the right direction. Long feedback loops gives us less room to make mistakes, and play around the edges Short feedback loops give us more instantaneous feedback, so that we can reach our goals. More data, gives us greater visibility of patterns … Adding sensors to ourselves gives us more data, so we can see more patterns. Habit modification: I can’t stick to the plan, unless I have some way to tell I’m heading in the right direction. If we can measure minute changes, you get direct feedback that your actions are working to reach your goals. Neuroplasiticity/evolution/adaptation.
- - cost vs function - democratizing research. (I,e, seti @ home) if each person does a little bit of research about them selves, it contributes to a greater learning. Most people seem to focus on the brain. That’s cool, I get it. It’s complex and we don’t understand it. We focused on the brain and made expensive devices only a few special groups of people could afford. EEG,MRI,NIRS,TMS,ECT,MEG An MRI machine costs around 3m million dollars. An EEG that you can publish a paper with costs $40K (Biosemi) A wheatstone bridge, the circuit most commonly found behind galvanic skin response, costs less than $2 A pulse sensor, made from an ambient light sensor that you find in laptops, and an LED costs less than $2. Cheap, and readily accessible. Prohibitive and hard to get your hands on. Also, none of them are yet high enough in fidelity to be able to detangle the complex information being generated within our 100 billion neurons. These technologies are currently less accessible, and more complex. So far, much of this research has centered on the brain, as we regard that as the CPU that controls EVERYTHING. What if… the body mattered too???! What if the body could tell us about our mental state, or even controlled many aspects of our mental state?
- Non-invasive biosensors – likely to be the first to market. Cheap, mass produced, massively powerful datasets to assess health. Lab-on-chip- more readily available bloodwork, analysis of blood, saliva etc to diagnose current state Neurofeedback – EEG zeo, more in depth sleep monitoring, Emotiv- brain computer interfaces. Brain training – quantified mind, doing lots of N-back tests Nootropics-choline, piracetam More research into how pharmaceuticals effect our body (not my field, I’ll just stick with the engineering approach for now) -

- - describe more. Transcranial direct current stimulation From the electrical signals coming out of your brain you can train y See sleep states Picture of the zeo
- Stroop task – read the color of the ink as fast as possible.
- Describe the sensors on this thing. Add video of pyrocardium That chair that people sat in. heart beat amplifier.
- Explain what we can see from relatively cheap sensors. These are all great measures… for sure… but I honestly don’t care about them unless they effect my health in some way. We have to measure useful things, that map back into our current understanding of how the body works, so we can understand it more. Here are some things we can do with it: Circadian rhythms and sleep analysis, slow wave sleep for memory consolidation tissue regeneration(muscle building) Activity level, time spent exercising, sleep (time spent being still), number of steps taken, categorization of periodic motion(sex?), gait analysis. parasympathetic nervous system balance. But mostly, we can collect this data, and use the cloud and data analysis tools that have been developed for other services… on health… or rather wellness, as there is too much liability surrounding health to even mention its name. Now I’ve talked about health and the body, I want to talk about how these accurate cheap measures are in fact good proxies for our mental states, and give us an insight into what our brain is doing too.

- It seems that it’s possible that the mind and body are one and the same, and effect each other. The egyptians felt so sure that the heart controlled everything, that they pulled the brain out through the nose and threw it away. The autonomic nervous system carries information from the nervous system to the brain. Gives the brain feedback from organs, heart, skin etc. The vagus nerve is associated with the function of many brain systems and vagus nerve stimulation is used to treat anxiety disorders, alzheimers, depression, migraines, tinnitus. Vagus nerve regulates sympathetic and parasympathetic nervous system. Connects to brain stem VNS has been used for depression, HRV and coherence for relaxation, some papers say if you stimulate the vagus nerve in the right way you have an orgasm. Most information goes from the vagus nerve, through medulla oblongata into brain stem… not vice versa. -- the longest of all the cranial nerves whose name is derived from Latin, meaning "wandering." The vagus nerve meanders from the brain stem through the neck and finally ends up in the abdomen.
- Stress- what if, you knew how stressed you were, when you last ate food, and if you were under slept. Would you then make a different decision? It turns out that both our gut and our brain originate early in embryogenesis from the same clump of tissue which divides during fetal development. While one section turns into the central nervous system, another piece migrates to become the enteric nervous system. Later the two nervous systems connect via a cable called the vagus nerve -- the longest of all the cranial nerves whose name is derived from Latin, meaning "wandering." The vagus nerve meanders from the brain stem through the neck and finally ends up in the abdomen. There's the brain-gut connection. More than 90% of the body's serotonin lies in your gut, as well as about 50% of the body's dopamine.
- Understanding more about the body Great for democratizing wellness in parallel with the sensor revolution Simple sensors can tell us complex and important things More Data =>better questions better health, better communication, heightened self-awareness, enabling self-control through changing habits Mussa Ivaldi – the point of this slide is that a decerebrated cat(it’s had it’s head/vagus nerve servered from it’s body, still does a lot of stuff… here it goes from walking on a treadmill, to running, without its brain connected to its body. Processing is done throughout the body… perhaps the Egyptians were right?
- What if you could – sense fear? emotional arousal during a conversation? Whether the person you are talking to was relaxed or stressed? Would you respond to them differently? Would you make different decisions? Would it make that boardroom meeting any different? Would it help you buy a used car?
- Better health/longevity Enhanced self awareness Augmented communication with others To modify our own habits- smaller feedback loops, allows us to change faster, more accurately. Heightened adaptability : Evolution? Slowly, the distance between each of is decreases, as we all endeavor to increase our overall awareness of our state, we share data, and meld… into one… like the borg. The borg were a giant hive mind, so networked to each other, that they were far more intelligent, than any individual could ever be. Far more efficient, far more aware. However, their one downfalling, is that they are thought as one. Once people see the advantage and the technology develops, people will start taking larger risks, including invasive sensors to enhance themselves, becoming part of the borg?
