1. Here we see a setup used in the lab of Dr. Richard Davidson, PhD.
- Richard Davidson is Psychologist, Neuroscientist, at the University of Wisconsin, Director of the Center of Healthy Minds:
In his lab, there is an equipement for:
- Real-time respiraton measurement
- Real-time pulsoximeter measurement
- Eye tracking as shown in an example observing the right eye of Mingyur Rinpoche
- A 256 EEG setup for brain electrical measurement
- Functional magnetic resonance imaging (fMRI) to measure small changes in blood flow that occur with brain activity, here shown in the example of Mingyur Rinpoches brain
- Gamma wave oscillations in the brain of Mingyur Rinpoche where very visible and very fast frequency, but they can also be seen in ordinary persons
- Do we also see our Gamma waves with our setup at home?
Equipment for mediation research at home consists for instance of:
- The setup of How to Electronics from India:
it measures:
- room temperature
- room humidity
- heart rate
- bood oxigen
- body temperature
- There is currently no MQTT interface available in the instruction of the IoT Based Patient Health Monitoring System using ESP32 Web Server. But there are instructions available how to stream sensor data over ESP32 to Home Assistant:
- These instructions can be modified for the How to Electronics setup. Once sensor data are streamed into Home Assistant, they can be exported to InfuxDB for data analysis.
The second part comes from OpenBCI
- In the example we can see Shirley Zhang with an OPENBCI Open Source EEG headset for reading brain data and dispaying it in live time with a a 3d printed headset
- On the backsite we can see the processing unit which converts the data from analog to digital
- In the example it transmit brain data to your computer via Bluetooth
- To join the sensor data from the setup of How to Electronics with sensor data from the OPENBCI EEG headset, we need the OpenBCI WIFI shield which can transmit the brain data over the MQTT protocol.
- With the MQTT protocol we can stream the data over several pathways into InfluxDB as discussed here on this site.
- Once the sensor data from the How to Electronics setup and from the OpenBCI setup are streamed to the InfluxDB, we can start doing physiology.
Unfortunately, the OpenBCI WIFI shield currently has issues and needs to be repaired. Therefore research at home is not possible, we need to go to the lab.
