#Catecholamine excess is an uncommon but severe cause of #hypertension, sometimes demanding unique considerations that guide management, with the occasional use of less common agents for treatment www.thelancet.com/journals/lan...

We propose #catecholamine (dopamine, noradrenaline, and adrenaline) inactivation as the fundamental biological process underlying sleep’s numerous benefits. #aging #evolution

Experimental design and effects on peripheral arousal markers. Top left: Design was within-subject, double-blinded, randomized, and placebo-controlled (Materials and methods). Additionally, the stimulus-response mapping was counterbalanced within participants Bottom: Schematic sequence of events during the spatial contrast discrimination task (Materials and methods). Participants reported the location of the highest contrast Gabor patch (difference in contrast is high for illustration only). Top right: Heart rate and pupil size measured as the average across task blocks (Materials and methods), separately for placebo and atomoxetine sessions. Every connecting line is a participant; large data points in the middle are the group averages.
How do catecholamines like #noradrenaline influence perceptual #DecisionMaking? @degeelab.bsky.social @donnerlab.bsky.social &co show that higher #catecholamine levels reduce individual choice history biases by dampening bias in the accumulation of sensory evidence @plosbiology.org 🧪 plos.io/4mMmNNX

3因素影響冬天血壓變化
●溫度
氣溫降低會導致交感神經系統活化及
#兒茶酚胺
（ #catecholamine ）的釋放，引起心跳加快及周邊血管收縮造成阻力上升，因而促使血壓升高。
此外，血管內皮細胞的活性在冬天也會有所改變，例如其所分泌促進血管擴張的一氧化氮合成酶（NO synthase）
在溫度高的表現就比溫度低明顯。
●維生素D
目前認為，維生素D可能會抑制引起血壓升高的腎素（Renin）之生成。在冬天接受到的紫外線較少，所以生成的維生素D也比夏天來得低。
