Detailed explanation-1: -Broca’s aphasia results from damage to a part of the brain called Broca’s area, which is located in the frontal lobe, usually on the left side. It’s one of the parts of the brain responsible for speech and motor movement.
Detailed explanation-2: -Broca’s area is also known as the motor speech area. It is near the motor cortex and utilized in speech production, located in the inferior frontal gyrus. This area regulates breathing patterns while speaking and vocalizations required for normal speech.
Detailed explanation-3: -Broca’s area is a key component of a complex speech network, interacting with the flow of sensory information from the temporal cortex, devising a plan for speaking and passing that plan along to the motor cortex, which controls the movements of the mouth.
