Frontal Lobe
What is the function of the motor cortex?
The motor cortex controls voluntary movement.
What is the function of the temporal lobe?
Processing auditory information, encoding memory, understanding language
What is the function of the occipital lobe?
Visual mapping, identifying features, visual recognition
What is the main function of the parietal lobe?
Interpereting and perceiving senses, as well as spatial awareness
During a football game, a player suffers a severe concussion. In the weeks following the injury, he is able to speak fluently, but he has severe difficulty understanding what his coach is saying to him, and he struggles to form new memories of his plays. Which area of the brain was most likely damaged?
Temporal lobe
This area is in the frontal lobe and coordinates the physical movements required to speak.
Broca's area
What area in the temporal lobe understands language?
Wernicke's area
What does the primary visual cortex do?
Processes visual information from the eyes
What is spatial awareness?
Determining the position of body in space
An elderly patient suffers a stroke. While she retains her full intelligence, memory, and physical mobility, she completely loses her ability to track moving objects visually. When a ball is thrown to her, she sees it in one position, and then it suddenly appears in another, as if she is watching a movie missing half its frames. Which lobe of the cerebral cortex was most likely damaged by the stroke?
Occipital
Name 3+ functions of the frontal lobe.
Any of these:
Registers awareness of sound, groups sound sequences together
Where is the occipital lobe located?
Right above the cerebellum - directly beneath the parietal lobe
What is the function of the somatosensory cortex?
Processes sensory information, allows for the body to feel and react to physical environment
While working at a construction site, a worker is struck by a stray piece of debris. While he fully recovers his physical mobility, speech, and memory, his coworkers notice a drastic shift in his behavior. He has transformed from a polite, reliable, and emotionally controlled person into an impulsive, irritable individual who frequently makes inappropriate remarks. Damage to which lobe of the brain best accounts for these changes?
Frontal
What is the function of the pre frontal cortex?
High level thinking, personality, and behavior control
Where is the temporal lobe located?
Directly behind the temples, and above the ears
What kind of things does the occipital lobe help identify?
Color, familiar objects, faces, symbols, shapes
Where is the parietal lobe located?
Near the top and back of the brain
After a bicycle accident resulting in a head injury, a patient reports a strange symptom: when someone places a key or a coin in her left hand while her eyes are closed, she can feel that an object is there, but she cannot identify its texture, shape, or size. However, her vision and motor movements remain completely unimpaired. Damage to which lobe of the brain best explains her condition?
Parietal
Where is the frontal lobe located?
Very front of the brain, directly behind the forehead
How does the temporal lobe enforce memory storage?
Turns short term memories into long term memories
True or false: there are left and right occipital lobes
True or false: the parietal lobe contains the motor cortex
False
An artist is sitting in a quiet studio, intently painting a landscape. As she works, she is simultaneously focused on the vivid colors of the sunset on her canvas and the physical, textured feeling of the paintbrush handle gripped tightly between her fingers. Which two lobes of the cerebral cortex are most actively involved in processing these two specific sensory experiences?
Occipital and Parietal
