-Provide the correct answer including the letter associated with the answer (E.g. "B: +60 mV)

- Provide reasoning for your incorrect answer and/or explanation for the correct answer. (E.g. "I mixed up sodium and potassium and incorrectly provided the equilibrium potential of potassium, which is -90mV, the correct answer for sodium is +60mV). 

 

 

 

 

Gray matter is to white matter as __ are to __

A. gyri and sulci

B. cell bodies and axon tracts

D. Oligodendrocytes and schwann cells

 

A spilt brain patient  is presented with instructions in their left visual field to draw a circle.  The experimenter verbally asks the patient  to explain why they drew a circle. Which of the following responses is the patient MOST likely to report?

A."I was drawing a clock."

C. " I did not draw a circle"

D. "They will not respond"

 

Based on what you have learned about laterality, which of the following statements is most accurate?

A. People utilize the right hemisphere for visual spatial tasks.

  C. both hemispheres play a role in most tasks in all people, working in concert with each other.

D. The hemispheres are functionally identical.

 

Consider a cognitive neuroscience study investigating the brain structures activated while reading a sentence. What aspect of brain activity measurement would determine the best method to use in this task?

A. Spatial resolution

C. sample size

D. non invasiveness

 

Assessment of the visual processing carried out by each hemisphere in split- brain patients usually involves the brief simultaneous presentation of different stimuli to each visual field while the participant fixates on a central point in space. Why is it necessary to ensure that stimulus presentation is brief?

a. if the stimuli were presented over longer intervals, information would be transferred between the  hemispheres through the corpus callosum.

c. the short presentation time is necessary to prevent eye movements, which would redirect information across the visual fields.

d. increasing the presentation time increases task difficulty for split-brain patients.
