Wire in the blood, I think, is a veiled reference to the phrase 'ghost in the machine'
from wikipedia
The ghost in the machine is British philosopher Gilbert Ryle's derogatory description for René Descartes' mind-body dualism. The phrase was introduced in Ryle's book The Concept of Mind, written in 1949,
to highlight the perceived absurdity of dualist systems like Descartes'
where mental activity carries on in parallel to physical action, but
where their means of interaction are unknown or, at best, speculative.
