Frontal Lobe
What is one major function of the frontal lobe?
Movement, decision-making, thinking, logic, emotions, speech, alertness, behavior, planning, sense of taste, short term memory
What is one major function of the parietal lobe?
-process sensory information (touch, taste, temperature)
-spatial abilities
-math
-reasoning
What is one major function of the temporal lobe?
Hearing, auditory processing, comprehending language, remembering verbal information, facial recognition, long term memory
What is one major function of the occipital lobe?
-Sight
-color perception
What is one major function of your cerebellum?
-balance
-muscle control
-coordination
Where is the frontal lobe located?
The frontal lobes are located directly behind the forehead
Where is the parietal lobe?
It is at the top of the brain above the occipital and temporal lobe.
Where is the temporal lobe located?
It is underneath the parietal lobe and the frontal lobe, stretching back to the occipital lobe.
Where is the occipital lobe located?
The back of your brain, underneath the parietal lobe.
Where is the cerebellum located?
It is not one of the lobes of your brain, but is instead tucked underneath the temporal and occipital lobes, next to your brain stem.
What might happen if you have damaged your frontal lobe?
You will struggle with:
-losing movement of various body parts
-inability to plan and sequence of complex movements needed to complete multi-stepped tasks (like making a sandwich)
-inability to express language
-inability to focus on a task and to filter out distractions
-mood changes
-solving problems
-controlling a response or impulse
-reduced motivation / initiation / persistence on activities
-changes in personality
What might happen if you damage your parietal lobe?
You will struggle with:
-drawing objects
-telling right from left
-spatial disorientation / body awareness and surrounding spaces
-reading / math
-focusing on visual attention
-motor planning and complex movements
What might happen if you damage your temporal lobe?
You will struggle:
-understanding spoken words
-paying attention to what you see and hear
-identifying objects
-learning and retaining new information
-memory
-persistent talking
-recognizing faces
What might happen if you damage your occipital lobe?
You will struggle to:
-find objects
-identify colors
-hallucinations
-illusions or accurately seeing objects
-recognizing drawn objects
-reading and writing
What might happen if you damage your cerebellum?
You will struggle with:
-coordination of fine movements
-walking
-reaching out and grab objects
-tremors
-dizziness
-slurred speech
-making rapid movements
What is one real world example of using your frontal lobe?
-Planning what you are going to do next weekend.
-Feeling sympathetic for your friend who fell on the playground and deciding to help them.
-feeling rewarded for doing something well in class.
-deciding to raise your hand instead of blurting out the answer
What is one way you could test if someone has a fully functioning parietal lobe?
Answers will vary, but you would need to design an experiment with a control and variables, with specific measurements to determine the range of function and the effectiveness of brain function.
While a general impression regarding level of consciousness, orientation, and language can often be made while taking a history, casual assessment of functions predominantly subserved by the parietal lobes is more difficult. A variety of formal cognitive tests can assess parietal lobe function, and typically include visual-constructional tasks (for example, Rey-Osterrieth Complex Figure, drawing interlocking polygons (as on the MMSE), clock drawing/setting), visual perceptual tasks (for example, time perception, Benton Judgement of Line orientation, Ravens Progressive Matrices, Hooper Visual Organization test), right-left orientation, and arithmetic/calculations (WAIS-R performance subtest).1 However, most of these tests require considerable time and expertise to administer in addition to equipment that may not be available in a clinic or emergency department setting.
Which of the following are NOT functions of the temporal lobe?
a) auditory processing
b) facial recognition
c) long term memory
d) coordination of movement
d) coordination of movement
Describe a scenario where it would be very dangerous to lose the function of your occipital lobe. Explain why it is so dangerous.
Answers will vary, Ms. Rebecca will judge if answer is correct.
Students must demonstrate knowledge of occipital lobe function, and the consequences of loss of function.
What is one real world example of using your cerebellum?
Answers will vary, but anything relating to balance, muscle control, and coordination
What other area of the brain shares the most similarities with the frontal lobe?
Parietal lobe
How could you visualize the parietal lobe?
Magnetic Resonance Imaging (MRI) is a non-invasive imaging technology that produces three dimensional detailed anatomical images. It is often used for disease detection, diagnosis, and treatment monitoring.
Functional magnetic resonance imaging (fMRI) measures the small changes in blood flow that occur with brain activity. It may be used to examine which parts of the brain are handling critical functions, evaluate the effects of stroke or other disease, or to guide brain treatment.
Give three examples of why having a fully functioning temporal lobe would be very helpful in a foreign country?
-paying attention to what you see and hear
-understanding language - you will need to work really hard to know what people are saying
-you will not be able to remember what you've learned from the people you are visiting
-you will struggle to recognize the people who you are with, or developing new connections of what is familiar
Which of the following would NOT be impaired if you lost function of your occipital lobe?
a) drawing a picture during art
b) dancing and singing
c) reading during DEAR
d) playing the game board during circle
b) dancing and singing
Is it possible for your cerebellum to heal after being injured?
