Resumen

Diferencias sexuales en el laberinto acuático de Morris en ratas jóvenes: dimensiones temporales.Existen muchos factores que influyen en nuestra memoria. El lapso de tiempo entre la adquisición y la recuperación de información parece ser crucial. En este estudio se evaluó en el laberinto de Morris la memoria espacial en ratas macho y hembra a los 30 días postnatales, modificando el intervalo entre la fase de adquisición y recuperación. Se utilizaron tres grupos de ratas hembra evaluadas con intervalos de 1 minuto, 6 horas y 12 horas y un grupo de ratas macho evaluadas 12 horas tras la adquisición. La prueba de recuerdo revela una ejecución adecuada en el grupo de ratas macho y una tendencia en las hembras a buscar la plataforma en un cuadrante incorrecto cuando se utilizan intervalos de 6 y 12 horas. Estos resultados sugieren que las hembras forman una representación del entorno más débil, que podría verse alterada más fácilmente que en machos con el paso del tiempo
