The somatosensory cortex is the site that registers touch, pressure, temperature, and pain in the cerebral cortex. This area is also responsible for awareness associated with bodily movement and position.

There are two cerebral hemispheres in the human brain. Each cerebral hemisphere is divided into four lobes. These four lobes include the following: frontal lobe, parietal lobe, occipital lobe and temporal lobe. 

The frontal lobes contain the motor cortex, Broca's area, and frontal association areas. The right motor cortex is responsible for movement on the left side of the body and the left motor cortex is responsible for movement on the right side of the body. 

Broca's area is the area in the frontal lobe that directs the muscle movement patterns responsible for producing speech sounds. When a person suffers from Broca's aphasia they often know what they want to say but physically can not say it. 

The pons sits above the medulla, making up one of the two structures of the brainstem. It's responsible for aiding in coordinated movement. If a cat has had its reticular formation severed, which connects the pons to the thalamus, it will still carry out the function of the medulla and pons (heart rate and breathing and run, climb and groom) but because it lacks the connection to the higher parts of the brain, it will perform its movements without a purpose. For instance, it will run and climb without the intention of finding food.

Association areas are located in the cerebral cortex. They act in learning, speech, memory, etc. These functions are considered to be higher mental functions. 

These are not involved in motor or sensory functions.

The brainstem is made up of the medulla and pons. Together, these make up the oldest (evolutionarily speaking) region of the brain. In cases of patients with brain damage, there have been observations made that no higher brain power is required to control heart rate and breathing because it's all managed by the medulla. The thalamus is not technically part of the brainstem, although it does attach to it via the reticular formation.

The medulla and pons make up the brainstem. As does the cerebellum, also known as "the little brain. The cerebellum is responsible for nonverbal learning, memory and balance. The amygdala is considered to be a primitive structure in the brain, tied to fear response. All these structures can be observed in primitive animals. 

Broca's area, however, is tied to language expression - a more recently evolved capability. The "old" structures of the brain are old in terms of their evolutionary development.

The amygdala is responsible for evoking fear and aggression.

The "reward centers" in the brain were observed in the 1954 study by James Olds and Peter Milner where they mistakenly placed an electrode in a rat's hypothalamus instead of the intended reticular formation. They observed the rat continuously visiting the location where it had previously received the electrode stimulation. The rat continued to return to that location for what appeared to be some perceived reward.

The hypothalamus is responsible for maintaining body temperature, regulating thirst and hunger, etc. In a sense, it's like maintaining a body's equilibrium - that is, homeostasis. In doing so, this may require the activation of the pituitary (master) gland, which will in turn release hormones.

The occipital lobe is located far in the back of the brain. It is in charge of processing visual signals.
