Relating to a neurosurgical treatment that involves implanting electrodes deep within specific brain structures to deliver controlled electrical stimulation, primarily used for movement disorders like Parkinson's disease and essential tremor.
Compound term combining 'deep' (referring to structures far from the brain surface) and 'brain.' The technique was developed in the 1980s as a refined version of earlier brain lesioning procedures, allowing reversible modulation instead of permanent destruction.
Deep brain stimulation is often called a 'brain pacemaker' because it works similarly to a heart pacemaker, sending regular electrical pulses to normalize abnormal brain activity. What's amazing is that patients can sometimes see immediate, dramatic improvements - people with severe Parkinson's tremors can go from barely being able to write their name to having steady hands within minutes of turning on the device!
