1. Identify the four lobes of the cerebral cortex, and describe the sensory and motor
functions of the cortex. Your answer should include the description and function of
the following:
Frontal lobe: The frontal lobe is located right behind the forehead. It is involved in
thinking, problem solving, emotions, behavioral control, and decision making. It is involved
with cognitive functions.
Parietal lobe: The parietal lobe is located in between the frontal lobe, and the occipital
lobe. It is involved in perception, object classification, spelling, and knowledge of numbers.
But the most important function of the parietal lobe is that it processes sensory signals
from the body such as, temp, pain, pressure, and touch.
Occipital lobe: The occipital lobe is located all the way in the back of the head, behind
the parietal lobe. It is involved in processing visual signals and coordinating many different
aspects of vision. The occipital had two lobes called the primary visual cortex, and the
visual association cortex.
Temporal lobe: The temporal lobe is located near the ears. It is involved in processing
auditory memory, and auditory information. In the left posterior lobe there is an area
known as Wernicke’s area, which is important for language comprehension.
2. Describe the process of how the brain influences the daily lives of humans. For each
term below, describe its basic function and give an example of how each would work in a
day at school.
Please go in this order:
• Medulla: The medulla oblongata is responsible for regulating and maintain heart rate,
swallowing, digestion, and sneezing. It would work in school by keeping your heart
beating so you do not die. It would also help you with your breathing.
• Reticular formation: The reticular formation is responsible for regulating the intensity
of pain. It is also responsible for helping people focus on useful sensory input while
filtering out unnecessary stimuli. So, the reticular formation would work in school, for
example, if all your classmates were talking and the teacher starts talking, it would help
you ignore the other voices and focus on your teachers voice.
• Amygdala: The amygdala is involved in processing emotion and survival responses.
The amygdala would work in school, for example, if you were running in one direction,
and you see a kid in the corner of your eye running right at you coming from the other
direction, it would trigger response to get out of his path quickly, before you get hurt.
• Hypothalamus: The hypothalamus is involved in regulating basic needs such as hunger,
thirst, and temp control. The hypothalamus would work in school, for example, by
sending a signal that you are thirsty, and then you would ask the teacher if you could go
have a sip of water.
• Wernicke's area: Wernicke’s area is involved in processing both spoken and written
speech. Wernicke’s area of the brain would work in school, for example, if your teacher
asks a question, it will take in and process what the teacher just said.
• Broca's area: Broca’s area is involved in moving the muscles to create speech. Broca’s
area would work in school, for example, after the teacher askes a question and
Wernicke’s area has already processed it, it would then help you speak the answer to the
question.
• Frontal cortex: The frontal cortex is involved in planning appropriate behavioral
responses to external stimuli. The frontal cortex would work in school, for example, if
your friend asks you a question nicely, it will help you answer back to him nicely and not
screaming at him.
