Researchers found that insulin-like growth factor 2 (IGF-2) levels were increased in rats who underwent memory training using the shock avoidance test. Additionally, when a single dose of IGF-2 was injected into the memory region (hippocampus) of rats after two days of training, the experimental group that received IGF-2 have better memory retention and consolidation compared to the saline injected control group, strongly suggesting that IGF-2 is involved in memory consolidation.
In this study, memory in rats was studied using the "shock avoidance" test. This behavioral test consists of placing rats in a box that contains two chambers: one chamber was lighted while a dark chamber delivered strong electrical shocks to rats who entered it. Hence, rats learned to avoid the dark chamber during a two day training period. Scientists found that the natural levels of IGF-2 increased in the brain after two days of training during the shock avoidance test and that the levels persisted throughout the study suggesting a role of this protein hormone in memory consolidation. Moreover, rats who received a single dose of IGF-2 after two days of training had better memory retention and learned to avoid the dark chamber more times than the control group of rats.
