2. Figure 1
A rat choosing between two containers covered with differently scented lids.
The image shows a rat in a test arena choosing between two cups covered with lids saturated with different odors. The odor of one lid was previously experienced in the arena context shown, but the odor of the other lid had only been experienced in a larger arena with two concentric rings of cups. Rats significantly preferred the lid containing the odor novel to the test context and were rewarded with chocolate for making the correct choice. This finding shows that rats formed odor-context episodic memories. (Image courtesy Jon Crystal.)
