The frontal lobe is the part of the brain that controls important cognitive skills in humans, such as emotional expression, problem solving, memory, language, judgment, and sexual behaviors. It is, in essence, the “control panel” of our personality and our ability to communicate.
It is also responsible for primary motor function, or our ability to consciously move our muscles, and the two key areas related to speech, including Broca’s area.
The frontal lobe is larger and more developed in humans than in any other organism.
As its name indicates, the frontal lobe is at the front of the brain. The right hemisphere of the frontal lobe controls the left part of the body, and vice versa.
The frontal lobe is also the most common place for brain injury to occur. Damage to the frontal lobe can create changes in personality, limited facial expressions, and difficulty in interpreting one’s environment, such as not being able to adequately assess risk and danger.
