Stereotaxic coordinates for unilateral disconnection lesions

Lesion site	AP	ML	DV
RSP	−2.0	±0.3	−1.6 and −2.5
	−3.5	±0.4	−1.8 and −2.5
	−5.0	±0.4 and ±1.0	−1.6 and −2.2 (medial site), −1.6 (lateral site)
	−6.5	±0.8 and ±1.4	−1.6 and −2.2 (medial site), −2.7 (lateral site)
	−8.0	±1.0 and ±2.0	−2.0 (medial site), −2.4 (lateral site)
POR	+0.5	±4.4	−5.3
	−0.1	±4.4	−4.0

Note: Anterior–posterior (AP), medial–lateral (ML), and dorsal–ventral (DV) measurements for RSP lesions are derived from bregma, midline, and skull surface, respectively (measurements are in millimeters). AP measurements for POR lesions are derived from lambda. Electrolytic lesions were made by applying a 2.5 mA current for 15 s at each RSP site and for 10 s at each POR site. Lesion placement was counterbalanced between the right and left hemispheres across rats. ± indicates that a lesion was placed on either the left or the right hemisphere.
