Which of the following is true regarding sex differentiation of the brain?
A) The right hemisphere of the cerebral cortex is thicker in the female brain.
B) The corpus callosum is thinner in the male brain.
C) The male hypothalamus becomes estrogen sensitive and influences cyclic release of hormones.
D) When performing verbal and spatial tasks, men tend to use both brain hemispheres whereas women are more likely to exhibit patterns of hemispheric asymmetry.
Question 2
The greater thickness of the corpus callosum in women's brains than in men's brains allows for more intercommunication between the two hemispheres, which could account for why:
A) men typically exhibit less impairment of brain function than women do after comparable damage to one hemisphere.
B) females often score lower than males on tests of verbal skills.
C) female brains are less lateralized for function and male brains have larger asymmetries in function.
D) male brains are less lateralized for function and female brains have larger asymmetries in function.
