Fig. S1.

No change in CREB and CaMKIIα concentration was seen with training in the presence or absence of propranolol and/or lactate treatments. (A and B) Densitometric analyses of Western blots and representative images for CREB (A) and CaMKIIα (B) obtained with dHC extracts from untrained (naive) rats injected with vehicle and rats injected 15 min before training with vehicle, l-lactate, propranolol, or propranolol + l-lactate and killed 20 h after training. Data are expressed as the percentage (mean ± SEM) of mean values (100%) in vehicle-injected naive rats (n = 5–10 per group). Numeric values and detailed statistical analyses are reported in Table S3.
