Just watched Pineapple Xpress and hence in suitably inspired mood a couple of rare insights became self evident
)why does it take me to lie down in bed before I have a sixth sense house chores alarm bell ringing in my head telling me I haven’t closed the kitchen window and the food hasn’t been put in the fridge?
2)as I fumble to listen to my IPod in bed without wanting to overly distract other half how is it that I can disentangle the most complicatedly looking knotted set of earphones in the dark by feel alone???in fact probably better than I could do it by looking and
3) the weird moment as you slip into stage 1 sleep where you sense your body falling so much so that u startle yourself into waking…must be proof that the higher centres going on working but misinterpret the sudden loss of body tone as weightlessness ie the sense of ffalling.
this sensation is clearly as dramatic as a switch and it is the continuation of thought unfettered by proprioception that ffctively allows the free associations that comes with a wandering mind enabling occasional moments of non sequitor leaps of non logical truth.
so propriiception binds you to logic and the disconnection frees yoy from it.
the switch must be brsinstem led because the cognition vlearly continues and only aborts tge switch when yhere us enough ptoprioception eg in a train when your head lolls onto a strangers shoulder
so the switch myst be a combinatuon lock of peripheral stimuli eg
lying horizontal, a certain range of heart and respiratory rate, a change in alpha rhythms signifying eye closure and maybe a certain level of melatonin.
maybe thsts why melatonin diesnt jyst work on its own in natural sleep deprived ITU patients.
but given the right autonomic parameyers a bit of exogenous melatonin may turn out to be themissing ingredient for an exexhausted cortex.
ependymal cilia influences near wall neural excitability
maybe lying horizontal facilitates CSF dynamics to promote more even distribution of ionic currents and fields than a daytime gravitationally dependent CSF flow and maybefaciltates a more repair and reinforcing modality of neural networking…
mmmm….pineappke expressssssssss yum yum.
