Figure 8. Binge ethanol exposure during adolescence, but not adulthood, decreases choline acetyltransferase (ChAT) expression in the young adult basal forebrain.
(A) Immunohistochemical assessment of ChAT+IR in the medial septum/vertical limb of the diagonal band (Ch1/Ch2) revealed a significant 37% (±6%) reduction in subjects that received binge ethanol during adolescence (P28–P48), but not in adulthood (P70–P90). (B) Profile counts of ChAT+IR in the horizontal limb of the diagonal band/nucleus basalis magnocellularis (Ch3/Ch4) revealed a significant 34% (±10%) reduction in subjects that received binge ethanol during adolescence (P28–P48), but not in adulthood (P70–P90). Data are presented as mean ± SEM. * indicates p<0.05, relative to CON rats.
