Answer:
C) trephining
Explanation:
Trephination was an early medical treatment for mental illness, as well as for a whole range of other conditions. This procedure required surgery on the brain, as a hole was drilled into the skull using simple tools. This allows early doctors access to the brain, the blood vessels and meninges. This treatment was used for a great variety of conditions, such as intracranial diseases, epileptic seizures, migraines and mental disorders by relieving pressure.
