Brain blood flow increases during the first week of living at high altitude. We do not understand completely what causes the increase or how the factors that regulate brain blood flow are affected by the high-altitude environment. Our results show that the balance of oxygen (O(2)) and carbon dioxide (CO(2)) pressures in arterial blood explains 40% of the change in brain blood flow upon arrival at high altitude (5050 m). We also show that blood vessels in the brain respond to increases and decreases in CO(2) differently at high altitude compared to sea level, and that this can affect breathing responses as well. These results help us to better understand the regulation of brain blood flow at high altitude and are also relevant to diseases that are accompanied by reductions in the pressure of oxygen in the blood.
This research output has an Altmetric Attention Score of 11. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 20 December 2018.
All research outputs
#4,287,116
of 34,559,526 outputs
Outputs from Journal of Physiology
#1,663
of 12,292 outputs
Outputs of similar age
#25,476
of 257,146 outputs
Outputs of similar age from Journal of Physiology
#11
of 69 outputs
Altmetric has tracked 34,559,526 research outputs across all sources so far. Compared to these this one has done well and is in the 87th percentile: it's in the top 25% of all research outputs ever tracked by Altmetric.
So far Altmetric has tracked 12,292 research outputs from this source. They typically receive a lot more attention than average, with a mean Attention Score of 12.4. This one has done well, scoring higher than 86% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 257,146 tracked outputs that were published within six weeks on either side of this one in any source. This one has done well, scoring higher than 89% of its contemporaries.
We're also able to compare this research output to 69 others from the same source and published within six weeks on either side of this one. This one has done well, scoring higher than 84% of its contemporaries.
