Abstract
The possibility of carrying out inhibitory avoidance experiments, also called passive avoidance, with a two-way shuttle-box was tested in thirty-five OF1 male mice. Two intensity levels of shock (0.3 and 0.6 mA) and a non-shocked group of animals were employed in this experiment. Inhibitory avoidance conditioning was observed in the 0.6 mA group (statistically significant differences between the response latencies of Day 2 versus Day 1) but not in the case of the 0.3 mA group. These results allow us to conclude that it is possible to obtain inhibitory avoidance in a shuttle-box.
