Figure 1.
Upper panels show infusion locations for the lateral dorsal striatum (left) and lateral orbitofrontal cortex (right). Anterior-Posterior levels are measured in mm from bregma. The functional spread of lidocaine in individual rats is depicted by the filled circles, the radius of which is estimated from the spherical volume equation, V= 4/3 π r3 [38]. Lower panels show representative photomicrographs of guide and infusion cannulae tracks for the lateral dorsal striatum (left) and lateral orbitofrontal cortex (right).
