Figure 3. Muscimol injection prevents the expression of CR.

(a) Injection of GABA_A receptor agonist muscimol (red) or ACSF (blue) into the right caudal mPFC. (b) Top: experimental scheme, Bottom: muscimol markedly impaired the CR expression compared with ACSF (left). However, this impairment was reversible when the same rats were retested 24 h later in the absence of muscimol (right; n = 9 rats for ACSF group and n = 10 rats for muscimol group; N.S., not significant, ^***P < 0.001; two-tailed unpaired Student’s t-test). Data are represented as mean ± s.e.m.
