Estudio revela semejanzas entre el cerebro humano y el del perro

Fuente: BBC

Investigadores hA?ngaros buscan explicar por quAi?? los perros parecen estar en sintonAi??a con los sentimientos humanos. Ai??Al colocar a estos animales en un escA?ner, investigadores de HungrAi??a hallaron que los cerebros de los perros reaccionan a las voces de la misma forma en que lo hace el cerebro humano, especialmente cuando escuchan sonidos con carga emocional.

Las pruebas hallaron que las mismas regiones dentro del lA?bulo temporal se iluminaron tanto en las personas como en sus mascotas, cuando se activaron grabaciones de una misma voz humana. La risa humana tambiAi??n produjo similares patrones de actividad.

Los investigadores dicen que esto podrAi??a explicar por quAi?? estos animales parecen estar tan en sintonAi??a con nuestros sentimientos. Sin embargo, los cientAi??ficos encontraron que las respuestas en los cerebros de los perros eran mucho mA?s fuertes cuando se trataba de sonidos caninos que en el caso de sonidos humanos.
