Are languages processed in different parts of the brain?Brain exposed patients shown pictures, and asked to say “this is a ___”

Spot on brain is electrically stimulated.

If stimulation impedes production it’s a language area

Are certain areas particular to one language?

Yes, but more are common to both languages.
