You’re waiting for a train. A train that’ll take you far away. You know where you hope this train will take you. But you can’t know for sure. Yet it doesn’t matter. Now, tell me why?
A woman has reached the age of 24 without anyone realising she was missing a large part of her brain. […] The discovery was made when the woman was admitted to the Chinese PLA General Hospital of Jinan Military Area Command in Shandong Province complaining of dizziness and nausea. She told doctors she’d had problems walking steadily for most of her life, and her mother reported that she hadn’t walked until she was 7 and that her speech only became intelligible at the age of 6.
Doctors did a CAT scan and immediately identified the source of the problem – her entire cerebellum was missing. The space where it should be was empty of tissue. Instead it was filled with cerebrospinal fluid, which cushions the brain and provides defence against disease.
The cerebellum – sometimes known as the “little brain” – is located underneath the two hemispheres. It looks different from the rest of the brain because it consists of much smaller and more compact folds of tissue. It represents about 10 per cent of the brain’s total volume but contains 50 per cent of its neurons. […]
The cerebellum’s main job is to control voluntary movements and balance, and it is also thought to be involved in our ability to learn specific motor actions and speak.
