Assessment of cognitive and motor deficits in a marmoset model of stroke.

The Stroke Therapy Academic Industry Roundtable noted the need for standardized, well-accepted primate models of stroke to help develop both neuroprotective and restorative therapies. One primate model has been developed using the marmoset, a small New World species of monkey, in which long-term functional deficits can be assessed. The surgery and postoperative care of the animals is described, as well as the behavioral tests used to quantify the postoperative disability. The types of deficits seen are illustrated by reference to some of the findings with neuroprotective treatments. Nevertheless, the long-term nature and consistency of the motor deficits make this model ideal for assessing the worth of restorative therapies.
