Emory NBB 201 - Final Exam Questions
And All Answers.
Ventral vs Dorsal Pathways - Answer Ventral: what (identify objects)
Dorsal: where (track objects in space)
Prosopagnosia - Answer Failure to discriminate faces
- caused by damage to the occipitotemporal cortex (fusiform face area)
- can see parts of the face but not the whole picture
Human face processing - Answer Expression: superior temporal sulcus (STS)
Identity: fusiform face area (FFA)
Monkey face processing - Answer Expression: superior temporal sulcus (STS)
Identity: inferior temporal lobe (IT)
Why are human face patches more posterior and ventral than in macaques? - Answer
Expansion of the language cortex on the lateral surface of the temporal lobes -> face areas got
pushed to the ventral part of the temporal lobes
Core visual processing system - Answer Inferior occipital gyri: early perception of facial
features, sends info to:
-> STS (expression)
-> FFA (identity)
Extended visual processing system - Answer STS sends info to:
-> intraparietal sulcus (spatially directed attention)
-> auditory cortex (pre-lexical speech perception)
-> Amygdala/insula/limbic system (emotions)
FFA sends info to:
-> anterior temporal lobe (biographical info)
, Facial femininity - Answer Generally considered attractive
Caused by estrogen
Facial masculinity - Answer May not be considered attractive, as a function of individual
differences or hormonal factors
Caused by testosterone
Attractive faces stimulate activity in ____ and ____ - Answer __OFC__ and __NA__
- parts of the mesolimbic DA system where the VTA sends DA
- same places that are activated by food
Facial dominance - Answer More dominant male facial features are correlated with acquisition
of high rank in the military (higher dominance faces may have more T, but exact mechanism is
not known)
Most common form of fatal violence - Answer Males killing males
- women are more likely to be killed by an intimate partner than males are
Most common form of nonfatal violence - Answer Males killing being killed by strangers
Females are the default
gonads...
mullerian ducts...
wolffian ducts...
prenatal hormones... - Answer gonads... develop into ovaries
mullerian ducts... develop
wolffian ducts... regress
prenatal hormones... are not involved
Males deviate from the default
gonads...
