Figure 2. Effects of nerve growth factor (NGF) infusion into the entorhinal cortex on short- (A) and long-term (B) memory in a one-trial step-down inhibitory avoidance task. Data are reported as median (interquartile range) latency (in seconds) in training and test sessions. N = 11-13 per group. *P < 0.05 compared with the vehicle-treated group (Mann-Whitney
U-test). All groups showed significant training-test differences (P < 0.01, Wilcoxon test).
