the line where the map stops and the nerve begins
means The outer edge of settled or known territory — a border zone, or by extension the leading edge of any field of knowledge or endeavor.
from From Old French frontiere, 'front of an army, borderland,' built on front, meaning forehead or foremost part, from Latin frons (frontis), 'forehead, front.' So the frontier was literally the face a territory turned toward whatever lay beyond it — the part that meets the world first. English borrowed it in the late medieval period; centuries later America stretched the word westward into myth.
