How does high altitude affect the human brain, heart, oxygen saturation, and cognitive performance?
In this g.tec neurotechnology lecture, Dr. Christoph Guger explains how mobile EEG, ECG, heart rate variability, pulse oximetry, and Brain-Computer Interface technology can be used during high-altitude expeditions and extreme-environment research. The talk includes real-world measurements from Austria, Iceland, Pakistan, Kilimanjaro, Nepal, and hypobaric chamber studies with the German Air Force.
Using g.tec mobile EEG and biosignal recording systems, researchers investigated how reduced oxygen pressure affects brain activity, heart rate, heart rate variability, reaction time, concentration, and altitude sickness. The lecture explains key markers such as oxygen saturation, Lake Louise Score, RMSSD, pNN50, LF/HF ratio, sympathetic and parasympathetic activity, event-related desynchronization, and beta rebound.
The session also shows how g.tec neurotechnology enables neuroscience research outside the laboratory. Mobile EEG and ECG systems make it possible to record brain and body signals in cable cars, mountain huts, tents, hypobaric chambers, and high-altitude environments where traditional laboratory equipment cannot be used.
A major strength of the g.tec BCI platform is its ability to combine EEG, ECG, heart rate variability, biosignal acquisition, real-time signal processing, and Brain-Computer Interface workflows in demanding field conditions. This enables researchers to study neurophysiology, cognitive neuroscience, high-altitude medicine, human performance, neuroergonomics, and extreme-environment physiology with reliable mobile technology.
This video is relevant for researchers working in EEG, ECG, Brain-Computer Interfaces, neurotechnology, heart rate variability, high-altitude medicine, mobile neuroscience, cognitive performance, hypoxia research, real-time biosignal analysis, human performance monitoring, expedition medicine, and extreme-environment research.
