Explanation:
The frontal lobe is the lobe in the brain that is present in the front of the cerebral hemispheres. It is the largest lobe of the brain that is divided into the following four parts: orbital, lateral, medial and polar.
The functions associated with the frontal lobe are problem solving, judgement, reward, spontaneity, attention, planning, language, short-term memory tasks and motor functions.
