Figure 2
(a) Coronal section of torus semicircularis with subdivision boundaries outlined (L: laminar; P: principal; V: ventral; M: medial; OT: optic tectum; AD: anterodorsal tegmentum). Scale bar 0.1 mm. (b) High magnification showing silver grains over toral cell bodies. Scale bar 0.01 mm. (c) Mean expression levels of egr-1 (silver grains per pixel of cell area ± SEM) from radioactive in situ hybridization combined across four toral subdivisions for each of four acoustic treatments: P. pustulosus (), P. petersi (), noise (), and silence (). Statistical analyses were not performed due to small sample sizes.
