Doesn't the brain, too? It's blood-cooled. Being too hot makes it hard to think.

- sseagull 4y agoOne of the theories of brain evolution is that it increased in size after bipedalism due to the need for better cooling when standing up (the so-called Radiator Theory)
- ben_w 4y agoI think so? The point I was trying to make is they’re both under pressure to reduce wasted energy use.
- SemanticStrengh 4y agoThe brain doesn't consume enough energy to cause relevant heating. And it's more CBF cooled than blood cooled IMO
- londons_explore 4y agoThe brain generates 20 watts of heat. I assume that to work well it needs to stay within about 1 degree of 37C, like most other organs. Even the best manmade heatsinks can't dissipate 20 watts and have less than one degree of heating. So I hypothesize that heating is relevant.
