Frontal lobe - Definition

Ask a question


Located in front of the parietal and temporal lobes, the frontal lobe is responsible for voluntary motor coordination and rhythmic movements of the head and neck. This lobe is also involved in language and planning functions. It is separated from the other elements by the central sulcus and the lateral sulcus, and represents nearly a third of each hemisphere, divided into three parts on each side: the primary motor cortex, premotor cortex, and prefrontal cortex.
