Figure 4.

Effect of cold before and after training on learning and memory. Means and s.e.s are shown for both the time to stop responding to food (top) and for the time in the mouth during the first 5 min of a training or test session (bottom). (A) In one group (open bars, n = 5), animals were cooled and then trained until they stopped responding to food and then tested 0.5 hr after the training. In a second group (shaded bars: n = 6), animals were trained until they stopped responding to food and were then cooled and then tested 0.5 hr after the training. (B) One group (open bars, n = 8) was cooled, trained, and then tested after 24 hr. A second group (shaded bars, n  11) was trained, then cooled, and then tested after 24 hr. Cooling before training did not affect either the ability to learn or short- or long-term memory. Cooling after training did not affect short-term memory but did attenuate long-term memory.
