Imagine being able to talk to your neurosurgeon and giving him immediate feedback while he operates on your brain. That’s exactly what happens during an awake brain tumour surgery.

The brain is made up of a highly complex network of nerve fibres, akin to a series of interconnected tracks in the network that makes up an entire train system. If the fibre connections are disconnected, the function of the areas they are connected to, such as speech, vision or movement, will be affected. Disruptions can be caused not only by the tumour growth or blood clot itself, but also by surgical tools.
