Vanessa describes the EEG headset from iMediSync (아이메디신) she used to measure brain and HRV before and after her spaceflight on NS-22. iMediSync takes one step further by identifying early stage degenerative diseases (Alzheimer’s and Parkinson’s, for example), as their headset also administers transcranial photobiomodulation (tPBM) – low levels of red or near-infrared (NIR) light to stimulate neural tissues.

Just back from Guam, Vanessa becomes the First Woman to Reach Earth’s Highest and Lowest Points. She tells SkyNews about it on June 19, 2020.
