Had a left posterior basal ganglia stroke.was in hospital r sided hemiparesis...dr's did not explain poststerior ganglia?

Motor control center: It is an area in the deeper brain tissue involved in motor control. A stroke in these deeper areas is usually related to hypertension. Sometimes it may be related to diabetes or multiple sclerosis.

Brain relay nuclei: The basal ganglia are a group of nerve relay centers (nuclei) in central part of the upper brain. They work with other areas of the brain in the control of limb and body movements, eye movements, thinking, and emotions. Just behind the lentiform nucleus of the basal ganglia is the posterior part of the "internal capsule." stroke in this area causes a hemiparesis on the opposite side of the body.
