“…Since alpha/beta ERDs reflect movement preparation and execution and alpha ERD can also reflect inhibitory control, we suggest that long-term exposure to high altitude suppresses individuals' abilities to prepare and execute movement and to exert top-down inhibitory control. One recent study 49 reported similar reduced alpha and beta ERDs for high-altitude group, but using a mental rotation task.…”

“…The main contribution of the current study to existing literature is including altitude as a factor in the Go/ NoGo task and examining how exposure to high altitude affects neural oscillations during this task. Many studies have investigated the ERPs and neural oscillations in the Go/NoGo task 11,33,34 , and a few studies have explored how high-altitude exposure affects ERPs evoked by various cognitive tasks 9,48,49 . However, the influence of highaltitude exposure on neural oscillations induced by cognitive processing is largely unknown.…”

More than 80 million people worldwide permanently live at high altitudes, and living in such a hypoxic environment can impair cognitive functions. However, it is largely unknown how long-term exposure to high altitude affects neural oscillations underlying these cognitive functions. The present study employed a Go/NoGo task to investigate the effects of long-term exposure to high altitude on neural oscillations during cognitive control. We compared event-related spectral perturbations between the low-altitude and high-altitude groups, and the results revealed increased theta event-related synchronization (ERS) and decreased alpha and beta event-related desynchronizations (ERDs) during the NoGo condition compared to the Go condition. Importantly, the high-altitude group showed reduced alpha and beta ERDs compared to the low-altitude group, while the theta ERS was not affected by altitude. We suggest that long-term exposure to high altitude has an impact on top-down inhibitory control and movement preparation and execution in the Go/NoGo task.

“…In support of our findings, some previous studies have also shown decreased visual function in hypoxia exposure [ 6 , 8 ]. Similarly, event-related potential studies have found that chronic high altitude exposure decreased event-related desynchronization in the parietal and occipital regions [ 40 ] and decreased P50 delay activity amplitudes that reflected a predominantly pre-attentional inhibitory filter mechanism in regions [ 41 ] included by the visual mental rotation task. Considering our results, the increase in ReHo may be a compensatory mechanism for the visual cortex that needs to call for more cognitive resources to process information.…”

Damage to the visual cortex structures after high altitude exposure has been well clarified. However, changes in the neuronal activity and functional connectivity (FC) of the visual cortex after hypoxia/reoxygenation remain unclear. Twenty-three sea-level college students, who took part in 30 days of teaching at high altitude (4300 m), underwent routine blood tests, visual behavior tests, and magnetic resonance imaging scans before they went to high altitude (Test 1), 7 days after they returned to sea level (Test 2), as well as 3 months (Test 3) after they returned to sea level. In this study, we investigated the hematological parameters, behavioral data, and spontaneous brain activity. There were significant differences among the tests in hematological parameters and spontaneous brain activity. The hematocrit, hemoglobin concentration, and red blood cell count were significantly increased in Test 2 as compared with Tests 1 and 3. As compared with Test 1, Test 3 increased amplitudes of low-frequency fluctuations (ALFF) in the right calcarine gyrus; Tests 2 and 3 increased ALFF in the right supplementary motor cortex, increased regional homogeneity (ReHo) in the left lingual gyrus, increased the voxel-mirrored homotopic connectivity (VMHC) value in the motor cortex, and decreased FC between the left lingual gyrus and left postcentral gyrus. The color accuracy in the visual task was positively correlated with ALFF and ReHo in Test 2. Hypoxia/reoxygenation increased functional connection between the neurons within the visual cortex and the motor cortex but decreased connection between the visual cortex and motor cortex.

“…Recently, serial task-induced ERPs were measured in immigrants who had lived at Lhasa (3560 m) for more than 2 years. The HA immigrants showed reduced attentional resources with smaller P3 amplitudes ( Wang et al, 2014 ; Qiu et al, 2021 ), reduced attention reactions in visual search tasks with lower N2pc amplitudes ( Zhang et al, 2018a ), overactive performance monitoring with larger error-related negative and correct-related negative amplitudes ( Ma et al, 2015a ), impaired response inhibition in the conflict-monitoring stage ( Ma et al, 2015b ; Wang et al, 2021 ) and visual executive ability ( Ma et al, 2015c ) with smaller P3 amplitudes, slowed stimulus-driven behaviors and P3 magnitudes of resource allocation ( Ma et al, 2018a ), impaired spatial manipulation ability with larger rotation-related negativity amplitudes ( Ma et al, 2018b ), decreased P50 mean amplitude and delay activity amplitude of mental rotation ( Li et al, 2021 ), impaired spatial working memory with lower P2 and impaired verbal and spatial working memory maintenance with late-positive potentials ( Ma et al, 2019b ), and decreased alpha event-related desynchronization at the parietal-occipital regions and beta event-related desynchronization at the central-parietal regions within the time window (400–700 ms) in the mental rotation task ( Xiang et al, 2021 ). Taken together, these electrophysiological studies showed that prolonged exposure to HA mainly impairs the late processing stage of cognition due to insufficient attention resources.…”

With the advancement of in vivo magnetic resonance imaging (MRI) technique, more detailed information about the human brain at high altitude (HA) has been revealed. The present review aimed to draw a conclusion regarding changes in the human brain in both unacclimatized and acclimatized states in a natural HA environment. Using multiple advanced analysis methods that based on MRI as well as electroencephalography, the modulations of brain gray and white matter morphology and the electrophysiological mechanisms underlying processing of cognitive activity have been explored in certain extent. The visual, motor and insular cortices are brain regions seen to be consistently affected in both HA immigrants and natives. Current findings regarding cortical electrophysiological and blood dynamic signals may be related to cardiovascular and respiratory regulations, and may clarify the mechanisms underlying some behaviors at HA. In general, in the past 10 years, researches on the brain at HA have gone beyond cognitive tests. Due to the sample size is not large enough, the current findings in HA brain are not very reliable, and thus much more researches are needed. Moreover, the histological and genetic bases of brain structures at HA are also needed to be elucidated.
