Mean fluorescence intensity of coronal brain slices of rats indicating the appearance of the high molecular weight tracer Ovalbumin Alexa Fluor 555 Conjugate (OA-45; 45 kDa) at the level of bregma + 1.5 mm ∼ − 3.5 mm. The tail suspension test (TST) was applied for 5 min; all other procedures were as described in the Legend to Fig. 1. Means±S.E.M. from 6 animals. ^#P < 0.05; statistically significant difference from the respective TST values. One-way ANOVA followed by the Holm-Sidak (A, C) or Tukey test (B) were used as adequate. Two brain slices are shown out of the 6 slices prepared from each brain for the indicated treatments (D).
