Phantoms in the Brain

IDEA 1
Strange cases reveal the brain
Ramachandran, a neuroscientist, studies patients with unusual brain conditions to understand how the normal brain works. He believes rare cases can reveal deep truths about the mind. Unusual cases act like natural experiments that show what each part does.
IDEA 2
Missing limbs can still be felt
Ramachandran describes patients who feel sensations, even pain, in arms or legs that have been amputated. These phantom limbs show that the brain creates our sense of the body. The sensation seems real to the person.
IDEA 3
A mirror tricked the brain
Ramachandran describes his mirror box, which let patients see a reflection of their healthy hand in place of the missing one. For some, this eased painful phantom sensations. He presents it as a simple experiment with surprising results.

IDEA 1
Brain disorders reveal the self
Ramachandran uses unusual neurological cases to explore what makes humans unique. He argues that studying what goes wrong in the brain helps explain how normal thought, language and self-awareness work.
IDEA 2
Mirror neurons link us to others
Ramachandran describes mirror neurons, brain cells that fire both when we act and when we watch others act. He suggests they may help with imitation, empathy and learning from others, though the idea is still debated.
IDEA 3
Some people hear colours
Ramachandran describes synaesthesia, where people experience one sense through another, such as seeing numbers as colours. He suggests it comes from extra connections between brain areas. In his view, such crossed links could explain why the experience feels so real.
