Broca's area is present in which location?

Broca's area is present in which location?
Click to Flip
Left inferior frontal gyrus
Broca's area is not present in both hemispheres. Instead, it is within the inferior frontal gyrus of the dominant hemisphere.
The dominant hemisphere, in most individuals, is the left hemisphere. Therefore, Broca's area is most commonly present in the left inferior frontal gyrus.
