Topic: neurocognitive effects

In humans, the brain is the most oxygen-sensitive organ, consuming approximately 20% of the total oxygen supply despite representing only 2-3% of the body's mass. However, our understanding of the effects of altered oxygen levels on human brain function is incomplete. Studies investigating the neurocognitive effects of both elevated and reduced oxygen concentration report divergent findings, with improved and impaired performance reported in both conditions. Here, we employ an EEG approach to investigate the relationship between neural network dynamics and simple perceptual effects during inha
