Unit 3.4 - Cerebral Cortex Flashcards
What are the three sections of the frontal lobe?
It has the pre-frontal cortex, Broco’s area, and primary motor cortex?
What is the prefrontal cortex? What happens if there is little oxygen to it?
It takes the longest to mature, it is responsible for personality, reasoning/logic, and decision making. Little oxygen to it makes someone have impaired reasoning skills.
What happened to Phineas Gage? What are diseases that impact the pre-frontal?
He had a pole go through his pre-frontal cortex, which resulted in him going from being calm to being hostile and aggressive. Alziehmer’s and dementia attacks it.
What does the primary motor cortex do? What if there is little O2?
It is responsible for movement coordination and control.. The face’s coordination takes up the most space. Little O2 means that there is little coordination and slurred speech as mouth cannot move properly.
What does Broca’s area do? What happens if there is little O2?
It produces speech and language. This includes spoken, written, sign. Little O2 means slurred speech and misuse of words.
What is the parietal lobe responsible for? What are other is in it?
The parietal lobe is responsible for hand-eye coordination and spatial awareness. It includes the primary somatosensory cortex.
What is the primary somatosensory cortex? What happens if there is little o2?
It is responsible for skin sensitivity and sensation. Lips and face are the most sensitive. Little o2 results in lack of sensitivity and numbness.
What is in the temporal lobe?
The temporal lobe includes the primary auditory cortex and Wernick’s area.
What does the primary auditory cortex do? What would a lack of O2 cause?
It is involved in processing sound, music, rhythm,. A lack of O2 would make it someone snuggle to hear and crank up the volume.
What does Wernick’s area do? What does a lack of O2 cause?
It is responsible for language comprehension, when speaking and listening to others. A lack of O2 causes one to be unable to comprehend their own words and others.
What does the occipital lobe have?
The occipital lobe has the primary visual cortex.
What does the primary visual cortex do? What happens if there is a lack of o2?
It is responsible for processing visual info. If impacted, it can cause one to see stars. It helps process patterns and faces. Lack of o2 causes one to have a blurry vision.
