How do the structures of the hindbrain differ in function from the cortex?
What will be an ideal response?
ANSWER:
?The “primitive” brain consists of those structures which make up the hindbrain: medulla, pons, and cerebellum. The medulla allows for the preservation of such basic functions as heart rate, breathing; and such automatic functions as sneezing, coughing, and swallowing. The pons also helps in respiration, as well as dreaming, and sensory processing. The cerebellum aids in such functions as balance, muscle coordination, and motor-skill memory. Without the primitive side of our brain, some of the most basic life-support and neural processes would cease. In contrast, the most advanced portion of the brain is the forebrain. This area consists of the frontal, temporal, parietal, and occipital lobes. There are also locations within the forebrain of further specialization such as Broca’s area, and Wernicke’s area for language, and the motor/sensory cortexes. The various forebrain regions allow for further development of higher functions such as problem-solving, speech, reading, vision, etc.
