Description
Summary: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 ca se of the 0.3 mA group. These results allow us to conclude that it is possible to obtain inhibitory avoidance in a shuttle-box. Evitación inhibitoria con una caja de escape-evitación d e dos sentidos. Se estudió, en treinta y cinco ratones macho OF1, la posibilidad de ejecutar experimentos de evitación inhibitoria, también llamada evitación pasiva, con una caja de escape-evitación de dos sentidos. Se empleó shock de dos niveles de intensidad (0.3 mA y 0.6 mA) y un tercer grupo de animales que no recibió shock. Se observó condicionamiento de evitación inhibitoria en el grupo de 0.6 mA (diferencias estadísticamente significativas entre las latencias de respuesta del Día 2 con respecto a las del Día 1) pero no en el grupo de 0.3 mA. Nuestros resultados permiten concluir que es posible obtener condicionamiento de evitación inhibitoria con una caja de escape-evitación de dos sentidos.
