Question

It is estimated that 11% of Phineas' white brain matter was damaged and 4% of his gray brain matter was damaged. Why might this have been a positive thing for Phineas?

Gray brain matter can grow back

White brain matter can grow back

White brain matter is only used in children under the age of 5

Gray brain matter is only used in children under the age of 5

Answer 1

In the context of brain function and recovery, the most relevant option to suggest why the damage might have been seen as a positive for Phineas is:

**Gray brain matter can grow back.**

Neuroplasticity, the brain's ability to reorganize itself and adapt by forming new neural connections, means that damaged gray matter can sometimes recover or compensate for lost functions. In contrast, white matter, which consists of myelinated axons that connect different brain areas, does not regenerate as easily as gray matter. Thus, if Phineas's damaged gray matter had the potential to recover, it could be viewed as a positive aspect of his condition.
