Flashcards in Split brain surgery, plasticity and functional recovery after trauma Deck (10):
1

What did Sperry find?

Split-brain patients felt like two brains in one body for a few weeks after their surgery, then the left hemisphere became dominant again

2

What did Schneider think individuals with more education had that allowed them to recover faster?

Cognitive reserve

3

Name three individual factors that affect rehabilitation?

Perseverance, sex and age

4

Explain axon sprouting

Damaging axons results in lost connections to adjoining neurons, but these neighbouring neurons can grow extra connections to compensate and replace the function if the damaged axon and the replacements perform similarly

5

Explain increased brain stimulation

If the undamaged hemisphere is stimulated, recovery from a stroke is possible

6

Explain denervation supersensitivity

Axons that perform similarly to the damaged ones can become aroused to a higher level to compensate

7

Who studied split-brain patients?

Sperry

8

What practical applications does research into brain damage have?

Creating effective rehabilitation programmes

9

Define aphasia

An inability to understand or produce speech due to brain damage

10

Name two types of aphasia

Expressive and receptive
