Threat perception in the chameleon (Chamaeleo chameleon): evidence for lateralized eye use.

abstract：:Pigs are a valuable animal model for studying neurodevelopment in humans due to similarities in brain structure and growth. The development and validation of behavioral tests to assess learning and memory in neonatal piglets are needed. The present study evaluated the capability of 2-week old piglets to acquire a nove...
