The Brain That Changes Itself

1. IDEA 1

   The brain can change

   Doidge argues that the brain is not fixed after childhood but can reorganise itself throughout life. This ability, called neuroplasticity, overturned long-held beliefs. Doidge tells this story through scientists and patients.

2. IDEA 2

   Senses can substitute for each other

   Doidge describes Paul Bach-y-Rita's work helping people with damaged senses. Devices sending signals through other senses showed the brain could adapt. One woman regained her balance with such a device.

3. IDEA 3

   Brain maps shift with use

   Doidge describes Michael Merzenich's experiments showing that brain maps change with experience. Areas used often grow, while unused areas may be taken over. Competition for brain space shapes what we become.
