Quantification of ancillary damage to structures close to the RMTg in RMTg-lesioned rats

Brain structure	Small lesion group (% volume lesioned ± SEM)	Large lesion group (% volume lesioned ± SEM)	Ethanol intake—small lesion group (g/kg/24 h)	Ethanol intake—large lesion group (g/kg/24 h)	p value
IPN	7 ± 1	37 ± 5	6.3 ± 1.0	5.5 ± 1.2	0.11
MNR	9 ± 2	30 ± 5	6.2 ± 1.1	6.1 ± 1.4	0.50
pVTA	23 ± 2	39 ± 2	6.8 ± 1.1	5.5 ± 1.2	0.46

Rows indicate each brain structure analyzed. The first two columns indicate the volume of each brain structure lesioned in “small” and “large” lesion groups (determined by median split). Ethanol intake for each of the two groups is indicated for the small and large lesions groups in columns 3 and 4, respectively. The final column indicates significance values comparing levels of ethanol intake; there were no significant differences between any of the small and large lesions groups
