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

Aims: nowadays, commercial lightweight electroencephalography (EEG) headsets such as Emotiv EPOC and Muse are gaining popularity in the neuroscience community, mostly in research that monitors natural behaviour outside traditional laboratory settings. These devices often utilize only a few dry or active electrodes in specific locations and signal quality is often inferior compared to their traditional counterparts equipped with electrode caps that require conductive paste for proper functioning. In this study, we wanted to assess the feasibility of a portable, dry electrode-based EEG headset m
