“…Recent reports have largely demonstrated that HBO and NBO have positive influences on cognitive abilities, such as memory, visuospatial and verbal abilities, addition (related to working memory function) and n-back tasks (Chung et al 2009, Choi et al 2010, Schellart et al 2011. Our findings suggest that these reported neuro-psychological improvements might be associated during HBO exposure to rCBF distribution changes found in the regions encompassed in the DAS.…”

“…The majority of the neuroimaging studies investigating cerebral changes during various hyperoxic models have been performed in NBO (Ishii et al 1996, Boakye et al 2002, Kolbitsch et al 2002, Johnston et al 2003, Chung et al 2004, Bulte et al 2007, Choi et al 2010). On the other hand, brain changes during NBO have been investigated by techniques in which the inhalation phase was simultaneous to image acquisition (i.e.…”

The present study firstly confirmed the rCBF distribution increase during HBO in sensory-motor and visual cortices, and it showed for the first time a higher perfusion tracer distribution in areas encompassed in dorsal attention system and in default mode network. These findings unfold both the externally directed cognition performance improvement related to the HBO and the internally directed cognition states during resting-state conditions, suggesting possible beneficial effects in TBI and stroke patients.

“…Previous work has demonstrated that oxygen administration can improve performance on a number of cognitive measures in healthy adults (Choi et al 2010;Chung et al 2006Chung et al , 2007Chung et al , 2008aChung and Lim 2008;Chung et al 2004a, b;Moss and Scholey 1996;Moss et al 1998;Scholey et al 1998Scholey et al , 1999Sohn et al 2005). Such improvement occurred only when concurrently measured hyperoxia coincided with encoding of target material in memory tasks, or with performance of a reaction time task (Scholey et al , 1999.…”

“…These results support the idea that increased circulating oxygen is available to, and utilized by, metabolically active tissue including the neural substrates which underlie cognitive processing. This contention is supported by functional magnetic resonance (fMRI) studies showing cognitive enhancement and greater activation in brain loci associated with task performance under hyperoxic compared with normoxic conditions (Choi et al 2010;Chung et al 2004aChung et al , b, 2006Yu et al 2015;Kot et al 2015).…”

Oxygen Administration and Acute Human Cognitive Enhancement: Higher Cognitive Demand Leads to a More Rapid Decay of Transient Hyperoxia

et al. 2019

Both supplemental glucose and oxygen administration can improve aspects of cognitive performance. Previous research has established that more effortful cognitive processing results in reductions in peripheral blood glucose. We hypothesized that a similar phenomenon may be evident when measuring blood oxygen levels. This double-blind, placebo (air)-controlled, crossover study examined the effects of 100% oxygen administration and mental effort on heart rate and blood oxygen saturation. In counterbalanced order, twenty participants performed tasks where cognitive demand was relatively high (Serial Sevens) and relatively low (counting upwards) under conditions of normoxia and hyperoxia. Oxygen saturation and heart rates were comonitored using a pulse oximeter. Oxygen administration was associated with significantly fewer errors during Serial Sevens and the generation of more responses during counting. Both hyperoxia and heart rate were differentially affected by gas and task. Following oxygen inspiration, transient hyperoxia decayed significantly more rapidly during Serial Sevens than during the counting task. In the air condition, blood oxygen levels were raised during Serial Sevens compared with counting. The opposite effects were observed for heart rate. These results suggest that, following oxygen inspiration, a high cognitive load results in measurable uptake of circulating oxygen. This is likely to involve somatic and central processes.Journal of Cognitive Enhancement (2020) 4:94-99 https://doi.

“…Time-series data were filtered with a 240-s high-pass filter to remove artifacts due to cardiorespiratory and other cyclical influences. The functional map was smoothened with a 7-mm isotropic Gaussian kernel prior to statistical analysis [11][12][13][14][15][16]. Statistical analysis was done both individually and as a group using a general linear model and the theory of Gaussian random fields implemented in SPM 8.…”

Abstract. The change of neuronal activation due to the passive perception of various driving speeds in comparison to a reference driving speed was assessed using functional Magnetic Resonance Imaging. Videos recorded in real driving conditions on the road at driving speeds of 50, 70, 90, and 110 km/h were shown as visual stimuli. An experiment consisted of three blocks, each having a control phase (50km/h) and a stimulation phase (70, 90, or 110 km/h). In the passive perception of various driving speed differences, the areas related to visual cognition and spatial attention such as temporal, occipital, parietal, frontal areas, and cerebellum were activated. As the driving speed difference increased, the number of activated voxels also increased in the areas related to visual cognition. However, the visual cognition related areas showed a different pattern from the spatial attention related area with an increase of the driving speed difference. This implies that each brain area has a different level of involvement in the passive perception of the driving speed difference, although both visual cognitions related areas and spatial attention related area are related to it.
