Question

Which of the following is most posterior in location?

		Heschl s gyrus
		Wernicke s area
		Planum temporale
		Angular gyrus
		Arcuate fasiculus

Name the brain pathway that is degenerated first during the development of Alzheimer s Disease:

		the septohippocampal pathway
		the hippocamposeptal pathway
		the basocortical pathway
		the corticobasal pathway
		none of the above because Alzheimer s Disease is a loss nigrostriatal dopamine neurons

Which neurotransmitter would be the most sensitve marker to image using a PET scan for a biomarker for diagnosing Alzheimer s Disease?

		norepinephrine
		dopamine
		serotonin
		acetylcholine
		"none of the above because you have to image amyloid proteins, not a neurotransmitter"

"Which environmental stimuli cause burst firing or phasic release of dopamine as demonstrated in Wolfram Schultz studies, S-->R where S is environmental stimuli and R is increased action potentials in DA neurons:"

		"extremely salient stimuli (e.g., something went bang)"
		unexpected rewards (RPEs)
		conditioned stimuli predicting rewards (RPs)
		all of the above
		none of the above

"In Robbins & Everitt 1994, which neurotransmitter pathway when damaged produced omitted responses (one interpretation is impairment in movement, the other impairment in motivation)?"

		norepinephrine
		dopamine
		serotonin
		acetylcholine
		none of the above because premature responses were not observed in that experiment

Answer 1

The most posterior area is option. C)

Planum temporale  

It lies posterior to heschls gyrus so it is the part that lies most posterior and it is located in the temporal bone

Option a)Heschl's gyrus is a part of temporal lobe which is in front of planum temporale

Option b) Wernicke'srea located in the temporal lobe on the left side of the brain and is in front of planum temporale

Option d ) angular gyrus is lying in the anteriolateral portion of paritak lobe so is in front of the planum temporale the anterolateral region of parietal lobe

Arcuate fasiculus option e it lies near the wernikles area in the temporal lobe so it is anteriorr to planuk temporale
