To identify which specific brain areas are most active while people recall familiar nursery rhymes, researchers would be most likely to make use of a(n

fMRI

Explanation:

fMRI is a very important tool in both the field of clinical neuropsychology and cognitive neuroscience. In the clinical domain, it is mainly used to locate functional regions, such as those associated with motor or language processes, although new applications are being developed.

The fMRI is a neuroimaging exam that helps identify brain plasticity, assess memory, and track everything from normal growth development to how we age, healthy, or with diseases prevalent in advanced ages. This is a growing field of research and clinical research in humans and animals.

Using this test would be excellent for identifying which specific areas of the brain are most active while people remember family rhymes. This is because researchers could evaluate fMRI-generated images whenever participants resemble family rhymes.
