ABSTRACT
A great deal of biomedical research has provided experimental evidence of the function of specific neuropeptides in the development of autistic symptomatology. Interdisciplinary research in this area would provide a more comprehensive understanding of autism by integrating the findings and contributions from both behavior analysis and biology. In this preliminary interdisciplinary study, pregnant mice were injected with lipopolysaccharide - LPS (experimental group) on the 17th day of gestation and their litters were compared to the litters of mice that were not injected. Measures of social interaction were taken in two periods, namely when the pups were juveniles and when they were young adults, using an ABAB design consisting on the presence/absence of the mother in the chamber. The social interaction of each pup was assessed by observing the number of approaches it made towards its mother. Average velocity, calculated as distance traveled over time, for each mouse during the session was also collected. It was concluded that further refinement of the measure of social interaction was needed, and that a measure of behavioral development may prove useful in the construction of a mouse model of autism.
RESUMEN
Un gran número de investigación biomédica ha reportado evidencia empírica respecto a la función de neuropéptidos específicos en el desarrollo de la sintomatología del autismo. Se sugiere que con el fin de obtener una mayor comprensión del autismo es necesario establecer un campo de investigación interdisciplinario en el cual es integren contribuciones tanto del Análisis Comportamental como de la Biología. En este estudio interdisciplinario preliminar, ratonas gestantes fueron inyectadas con lipopolisacárido - LPS (grupo experimental) en el 17avo día de gestación. Las camadas de estas ratonas fueron comparadas con camadas control que no fueron inyectadas. Las mediciones de interacción social se realizaron en dos periodos, juvenil y adulto joven, utilizando un diseño ABAB que consistió en la presencia o ausencia de la madre en la cámara experimental. La interacción social de cada cría se evaluó observando el número de acercamientos hacia la madre. El promedio de velocidad, entendida como distancia recorrida sobre tiempo, de cada ratón también fue calculado para cada sesión. Se concluye que es necesario un mayor refinamiento de la medida de interacción social utilizada, y que la introducción de una medida de desarrollo comportamental sería útil en la construcción de un modelo animal de autismo.
