Following deep brain stimulation

Wired Science have got a great short film that follows a two people who have deep brain stimulation devices implanted in their brains to treat tremors.

Tremor is a symptom of Parkinson’s disease and this was one of the earliest targets for early DBS trials.

The film follows someone who has exactly this difficulty, plus someone who has a different form a tremor disorder, known as essential tremor, through the process of the operation.

While most people assume brain surgery is all pre-planned beforehand, for many treatments for cognitive or behavioural functions, the surgeons need to wake up the patient after they’ve open their skull to make sure they’re targeting the right place (and avoiding damaging essential functions).

In this case, they wake the patients up during neurosurgery so they can test out their movements while stimulating different areas of the brain, in a trial and error style.

Wired Science also has a shorter film online about the post-mortem dissection of a brain of a patient who had Alzheimer’s disease that’s also well worth having a look at.
