Resumen
Se estudiaron los efectos de la administración subcrónica de maprotilina (15, 20 y 25 mg/kg) sobre el aprendizaje espacial con el laberinto de agua de Morris, así como sobre la actividad general, en ratones machos y hembras. En la fase de adquisición, la administración de maprotilina (15 y 25 mg/kg) deterioró el aprendizaje en los machos pero no en las hembras, y no se observaron diferencias de sexo en el grupo control. En la fase de retención, la maprotilina, en las tres dosis, anuló las diferencias de sexo. Sobre la actividad general, la maprotilina, en las tres dosis, tuvo un efecto supresor de la misma y anuló las diferencias de sexo. El efecto sexodimórfico del fármaco en la fase de adquisición está en la línea del encontrado en otros experimentos, en los que se han usado otros fármacos, tanto antidepresivos como antipsicóticos, y otras tareas de aprendizaje en ratones. Este sexodimorfismo consiste en que el efecto del fármaco se observa sólo en los machos o, si se observa en los dos sexos, es mayor en los machos que en las hembras. La anulación de las diferencias de sexo en la fase de retención puede ser debida a la acción anticolinérgica de la maprotilina.
