Syrian golden hamsters with removals of the medial or ventral subfields of the frontal cortex at 4 days of age were compared behaviorally and neuroanatomically with hamsters with similar removals in adulthood. The behavioral results showed that hamsters with neonatal lesions show little sparing of species-typical behaviors such as hoarding and nest building. Study of the development of animals with early lesions showed that although as young juveniles the operated hamsters did not appear to be… CONTINUE READING
