Also, =of course= the neuralglia contractile dynamics enter into the tuning of
synaptic strengths... simply be-cause the neural stuff is embedded in, and
completely-supported by, the contractile neuralglia stuff... it doesn't take
much physical force to tune synaptic strengths when the geometry involved is
microscopically-refined via continuous TD E/I-minimization dynamics. ken
