A patient has damage limited to one region of the brain. The patient's muscles and sense organs function normally.
The patient completes two tests. The results are compared with the mean results for adults without brain damage.
| Test | Mean for adults without brain damage | Patient's result |
|---|---|---|
| Time spent inside a marked area during a 60 s balance test in s | 56 | 9 |
| Targets touched accurately out of 20 | 19 | 6 |
Use the pattern in the results to suggest the damaged brain region and give biological reasoning for your conclusion.
The patient and a group of adults without brain damage practise a new sequence of target movements for the same length of time. The adults can then perform the sequence automatically.
Suggest how the patient's performance is likely to differ after the practice. Give a biological reason for your answer.
