The three main sections of the brain are the forebrain, midbrain and the hindbrain. All the different parts of the brain process information and provide responses in terms of what we say, think, feel and do.
The cerebrum, responsible for thought and action is in the forebrain. The cerebrum is made up of four lobes, each with a different function. The frontal lobe deals with reasoning and problem solving. The occipital lobe processes vision. The parietal lobe is responsible for movement. Lastly, the auditory lobe processes all auditory functions. The limbic system, which includes the amygdale and the hippocampus which deal with memory and action, is also a part of the forebrain.
Though the thalamus and hypothalamus are located between the forebrain and the midbrain, they are considered to be a part of the fore brain. The thalamus processes stimulus and sensory information. The hypothalamus controls metabolism as well as portions of the nervous system.
The midbrain is quite small but it has the important job of connecting the forebrain to the spinal cord. Within it, the tectum which is the roof of the midbrain and the tegmectum, which is the floor of the midbrain process visual and auditory stimuli.
The cerebellum, pons and medulla oblongata are in the hindbrain. The cerebellum controls motor movement. However, together with the midbrain, the medulla oblongata and the pons are called the brainstem which connects with the spinal cord. The pons and medulla oblongata assist with varied functions from respiration, blood pressure to bladder control.
