Q: Ring finger -- The ring finger is the finger on which it is the custom in a particular culture for a wedding ring to be placed during a wedding ceremony and on which the wedding ring is subsequently worn to indicate the status of the wearer as a married person. It is commonly the finger between the middle finger and the little finger, and is so named because in some cultures it is the finger on which one usually wears a wedding ring after marriage. In some cultures the wedding ring is worn on the ``ring finger'' of the left hand and in others it is on the right hand. Traditionally, a wedding ring was worn only by the bride/wife, but in recent times more men also wear a wedding ring. It is also the custom in some cultures to wear an engagement ring on the ring finger.

Q: Hemispherectomy -- Hemispherectomy is a very rare neurosurgical procedure in which a cerebral hemisphere (half of the brain) is removed, disconnected, or disabled. This procedure is used to treat a variety of seizure disorders where the source of the epilepsy is localized to a broad area of a single hemisphere of the brain, notably Rasmussen's encephalitis. About one in three patients with epilepsy will continue to have persistent seizures despite epileptic drug therapy. Hemispherectomy is reserved for the most extreme cases of this one-third in which the individual's seizures are irresponsive to medications or other less invasive surgeries and significantly impair functioning or put the patient at risk of further complications. The procedure successfully cures seizures in about 85%-90% of patients. Additionally, it is also known to often markedly improve the cognitive functioning and development of the individual. Subtotal hemispherectomy sparing sensorimotor cortex can be performed with successful seizure control expected in 70-80% of patients. Even with the presence of widespread unilateral epileptogenicity or anatomic/functional imaging abnormalities, complete hemispherectomy can often be avoided, particularly when there is little hemiparesis.

A: can a person function with half a brain
