MT level is elevated 2 days after administration of NYT diet. MT immunostaining was determined in the dentate granule cell layer (GCL) 2 days after administration of NYT diet to mice (left). The data (mean ± SEM) indicate the rate (%) of MT staining after NYT administration to that after the control diet administration that was indicated as 100% (right). **, p < 0.01, vs. control (t-test). Control, 16 slices from 4 mice; NYT, 20 slices from 5 mice
