Electroconvulsive (ECT) is a device for the imposing the brain shock to patients who need to be treated with electric shock to diagnose the doctor. In this method, electrical current passes through two electrodes mounted on the scalp. This electric shock causes a massive firing of the brain's neurons.
Cerebral shunt in cases of hydrocephalus and other conditions that cause chronic increased intracranial pressure, a one-way valve is used to drain excess cerebrospinal fluid from the brain and carry it to other parts of the body. This valve usually sits outside the skull but beneath the skin, somewhere behind the ear. Cerebral shunts that drain fluid to the peritoneal cavity (located in the upper abdomen) are called ventriculoperitoneal (VP) shunts.
