Answer:
The two regions of the frontal lobe are the prefrontal cortex and the motor cortex.
The prefrontal cortex is responsible for higher cognitive functions such as decision-making, planning, and social behavior. It also plays a role in working memory, attention, and emotional regulation.
The motor cortex is responsible for planning, executing, and controlling voluntary movements in the body.
An association area is a region of the brain that integrates information from various sensory and motor areas and is involved in more complex cognitive functions such as language, perception, and memory. In contrast, a projection area is a region of the brain that receives direct sensory input or sends motor output to the muscles.
The other part of the frontal lobe that is only located in one hemisphere and is involved in speech production is called Broca's area. It is located in the left hemisphere in most individuals and plays a critical role in the production of articulate speech. Broca's area is involved in coordinating the movements of the mouth, tongue, and throat muscles required for speech production. Damage to Broca's area can result in a condition called Broca's aphasia, which is characterized by difficulty in producing speech.
