Fig. 6From: Dietary zinc supplementation rescues fear-based learning and synaptic function in the Tbr1+/− mouse model of autism spectrum disordersSupplementary dietary zinc does not restore impaired axonal projections in the anterior commissure in Tbr+/− mice. Representative images of Luxol fast blue staining performed on brain sections of wildtype Tbr1+/+ mice (WT) and heterozygous mutant Tbr1+/− mice fed with normal or high zinc diet (n = 7 animals/group). Black arrows indicate inter-amygdalar axonal projections at the anterior commissure. Scale bar = 2.5 mmBack to article page
