Rate of habituation to an enrichment device by rhesus macaques with lesions of the entorthinal cortex, hippocampal formation, or parahippocampal gyrus

Significant differences were found in the rate of habituation [to a rubber ball serving as enrichment] between animals with entorhinal or hippocampal lesions and normal control animals. This study addresses the special needs of monkeys with experimental cortical lesions and...

Caged stumptailed macaques voluntarily work for ordinary food

Ninety-nine of the biscuits were placed in a freely accessible dish attached to the mesh of the front of the cage. Thirty-three biscuits were offered in a food puzzle. Twenty-five percent (4/16) of the subjects ignored the food puzzle during...
