In this activity you will take a tour of the human brain and explore the major brain regions to discover the functions of each region or area.

Functional Specialization
• In terms of brain function, what is functional specialization? Hearing a sound or moving our thumb is controlled by a cluster of neurons. This gives us the capability of the nervous system. A neural network is the cluster of neurons.

• Why is the principle of complex communication important to understand? Each neural network is influenced by other networks or regions of the brain.

Test Yourself on Lower Brain Structures
Match each brain part with its function:

o__C_ Pituitary glandA. Located above the midbrain at the top of the brainstem; routes incoming messages from all the senses (except smell)
to the appropriate brain areas for processing
o_D__ MedullaB. Part of the limbic system; regulates hunger, thirst, and body temperature and contains the so-called pleasure centers of the brain
o__J_ PonsC. The master gland of the endocrine system
o_E__ Reticular formationD. Located in the brainstem; controls breathing and heartbeat o_F__ CerebellumE. A nerve network that runs up the center of the brainstem; plays an important role in controlling alertness and attention oI___ MidbrainF. Located at the back of the brainstem; assists in balance and the coordination of voluntary movement

o_A__ ThalamusG. Part of the limbic system; is involved in learning and in forming new memories
o_G__ HippocampusH. Part of the limbic system; is involved in regulation of the emotions of fear and rage
o_H__ AmygdalaI. Located near the top of the brainstem; integrates specific types of information from the eyes and the ears, and sends this on to other parts of the brain o_B__ HypothalamusJ. Located in the brainstem; controls breathing and heartbeat; connects the medulla to the two sides of the cerebellum to help coordinate and integrate movement on each side of the...
