概括

面部吹风稍微冷却大脑在高温的个体,但这种效果是最小的. 这项研究并没有证实在人类中选择性脑冷却 (SBC),而不是在动物中与动脉网络不同.

科学领域:

人类生理学人类生理学
热调节热调节热调节
环境热应力环境热应力

背景情况:

已知区域热性愉悦性,头部冷却在温和的炎热期间诱导舒适性.
头部冷却对大脑温度的影响的生理基础仍然不清楚.
选择性脑冷却 (SBC) 是一种在动物中观察到的,但在人类中尚未成熟的机制.

研究的目的:

测试面部或部冷却是否可以选择性地降低人类大脑温度.
在高温条件下研究人类中SBC的潜力.

主要方法:

8名男性志愿者接受了正常热和高热的治疗方案.
冷却方法包括面部吹风,额头和部导电冷却.
大脑温度的索引是耳和食道温度之间的差异.

主要成果:

与高温下食道温度相比,面部吹风显著降低了大脑温度 (T_es-T_ty = 0.08 ± 0.04 °C).
在额头或子冷却时没有观察到明显的脑冷却.
面部风扇的脑冷却效果是最小的.

结论:

面部吹可能会在高热症患者中提供轻微的脑冷却益处.
这项研究并未在人类中验证选择性脑冷却 (SBC).
与SBC机制相比,观察到的效应是最小的,与有动脉网络的动物相比.

Determining Temperature Preference of Mosquitoes and Other Ectotherms

Insects have an optimal environmental temperature range which they seek to remain within, and many external and internal factors can alter this preference. Here, we describe a cost-effective and simple method to study temperature choice, which allows insects to freely exhibit their natural...

Design and Analysis of Temperature Preference Behavior and its Circadian Rhythm in Drosophila

We recently identified a novel Drosophila circadian output, temperature preference rhythm (TPR), in which the preferred temperature in flies rises during the day and falls during the night. TPR is regulated independently from another circadian output, locomotor activity. Here we describe the design and analysis of TPR in...
