I don't know enough about Didier's point, but "noise" is in-there,
everywhere within the neural dynamics, from spinal cord to brain,
constituting a TD E/I(up) background with respect to which TD
E/I-minimization can always occur (all of AoK, especially Ap5).

I'm not Familiar with this usage.

I don't know if it's what Didier meant, but the ubiquitous outputs of
the "protopathic system" (AoK Ap3 and Ap5), Definitely makes all of what
might be referred to as "oscilators", within the nervous system,
"unstable. The TD E/I-minimization mechanisms "whittle" all this
instability back to Stability.

Work done in Physics ("Oscillons") Reifies the fundamentals I've
discussed from the perspective of Physics. Same-O-Same-O, but with the
Beauty of the Neural Topology built-right-in. ken collins
