Another way to think of this is the forebrain, midbrain, and hindbrain. The origins of these parts stem from where they came from in an embryo. The forebrain consists of the cerebral cortex, thalamus and hypothalamus primarily. The midbrain consists of the superior and inferior colliculi. In humans, this is the smallest division, with its ancestral functions delegated to higher cortical areas. The hindbrain is made up of the medulla (oblongata), pons and cerebellum. Thereโ€™s a lot of jargon, yes, thatโ€™s how neurobiology is. Feel free to message me if you wish to have more explanation for the individual structures!

The human brain is divided into three parts: the brainstem, the cerebellum, and the cerebrum. The brainstem is the posterior part of the brain which has the pons, the midbrain, and the medulla oblongata. The brainstem is mainly responsible for motor and sensory nerves to the face and neck (majority of the cranial nerves). The cerebellum which forms the hindbrain along with the brainstem and is located below the cerebrum. The main confirmed function of the cerebellum is motor function regarding contributing to coordination and precision. The cerebrum which is the largest section of the brain is made up of the cerebral cortex as well as several subcortical structures, including the hippocampus, basal ganglia, and olfactory bulb. The cerebral cortex is divided into two hemispheres (the left and the right) each of which has four lobes: the frontal, the temporal, the parietal, and the occipital.
