Researchers studied patients with damage to small regions of the cerebrum. Each patient completed the same memory and touch tests.
| Region of cerebrum damaged | Number of patients | Number who had difficulty remembering a list after 10 minutes | Number who could not consciously feel a light touch on one hand |
|---|---|---|---|
| region A only | 8 | 7 | 0 |
| region B only | 8 | 0 | 8 |
| regions A and B | 6 | 6 | 6 |
| a different region | 10 | 1 | 0 |
A researcher concluded that region A is involved in memory and region B is involved in consciously feeling touch.
Evaluate this conclusion using the data.
