Module 4.2 Flashcards
What is the relationship of columns to laminae? What can be said about the cells within one column?
Columns and laminae are perpendicular to each other. All the cells within a single column have similar properties to each other
What are the location and functions of the occipital lobe?
It is located at the posterior end of the cortex and it is the main target for visual information.
What are the location and functions of the parietal lobe?
The parietal lobe is between the occipital love and the central sulcus and it processes sensory info.
What does the postcentral gyrus do?
main target for touch sensations from body parts
What are the location and functions of the temporal lobe?
The temporal lobe is on the lateral side of both hemispheres and it is the primary cortical target for auditory info.
What are the location and function of the frontal lobe?
The frontal lobe extends from the central sulcus to the anterior limit of the brain and it is involved in decision making and problem solving.
Distinguish between the precentral gyrus and the prefrontal cortex.
The precentral gyrus controls fine movements. The prefrontal cortex is involved with planning, remembering, and making decisions about one’s actions.
What were the results of prefrontal lobotomies?
Apathy, a loss of the ability to plan and take initiative, memory disorders, distractibility, and problems with expressing emotions
What is working memory?
the ability to remember recent events and stimuli
What tasks show impairment after prefrontal damage?
After damage to the prefrontal cortex, individuals experience impairment in the delayed-response task, in which the individual is exposed to a stimulus and then after a brief delay, they are exposed to the stimulus again and have to recall it.
What is the Binding problem?
the question of how various brain areas produce a perception of a single object
What is the autonomic nervous system?
nerves that control heart, intestines, and other organs
What is the somatic nervous system?
nerves that in from sense organs and out to skeletal glands/muscles
