The attachment line, the connection, between the lateral ventricle blood vessel braid and the lamina affixa.
The outer attachment band of the blood vessel braid begins at the front, at the tip, on the lower/temporal horn of the lateral ventricle, runs backwards, together with the lateral ventricle blood vessel braid around the posterior pole of the thalamus (pulvinar), reaches into the central part of the lateral ventricle, pulls forward to the ventricular interlude and passes there into the organ band (taenia thalami).
