Your flight protection envelope


According to John Skoyles

This is remarkable and should cause a rethink about what controls our physiology. Tim Noakes has shown that the limits upon exercise are set in our brains. The brain creates a kind of “flight protection envelope” for our bodies that determines what we can safely do. But there is a considerable margin of safety (as in the design of flight protection envelopes for pilots and aircraft). Noakes calls it a “central governor“.

What Pugh shows is that this process also applies to thermoregulation. This is at present taken to be a purely low level process but it now looks that it is subject also to strong top down control.

This matters since it suggests physiologists might be grossly underestimating how far the brain including its higher cortical parts might be managing very basic processes– processes we usually assume run independently of the brain.

Nicholas Humphrey has suggested that even immune and other aspects of being sick are subject to such top down “health management system” processes. There is a revolution here awaiting to happen in biology and medicine.

  1. We might have a flight protection envelope for new ideas, new thinking. But that’s why the bad guys take it a step in the time, too. According to this

    In between come all the hundreds of little steps, some of them imperceptible, each of them preparing you not to be shocked by the next. Step C is not so much worse than Step B, and, if you did not make a stand at Step B, why should you at Step C? And so on to Step D.
