00:00Brain surgery is notoriously dangerous.
00:05After all, your brain is responsible for managing the functions of every other part of your body.
00:10But now neuroscientists in Switzerland say,
00:12extremely invasive brain surgery may not be needed in many cases moving forward,
00:16as they've developed a new way to monitor brain function
00:19by inserting a newly developed device through a tiny hole in the skull.
00:22Here's Professor Stephanie LaCour, one of the device's developers, to explain.
00:26So we have developed soft electrode array designed to record information from the surface of the brain.
00:33And these electrodes are so soft that they can be inserted just between the surface of the brain and the skull.
00:39And this could find application for recording of epilepsy seizures.
00:44So how big is the hole? Only around one centimeter.
00:46They say one of the biggest challenges was finding the right material,
00:49explaining that they were initially approached by a neurosurgeon asking for a less invasive option,
00:53as current methods involve cutting a large portion of the skull and removing it,
00:57then placing electrodes individually.
00:59Now they simply drill a hole and insert the soft-bodied flower-like device,
01:03which is then articulated via a liquid pressure system,
01:06allowing them to fan out the petals, positioning each in the exact right position on the surface of the brain.
01:12Let's take a closer look.
