One Reason That the Frontal Pole Has Received Less Experimental

Multiple Choice

One reason that the frontal pole has received less experimental attention than the lateral prefrontal cortex is because

A) the most anterior region of the prefrontal cortex is particularly prone to damage by cerebral hemorrhage,making this region more difficult to study in people.
B) the frontal pole is a much older region in phylogenetic terms,which is consistent with the observation that this region shows few individual differences.
C) the frontal pole is devoted to the sense of olfaction and is not believed to be involved in higher cognition.
D) the most anterior region of the prefrontal cortex is susceptible to imaging artifacts,making this region more difficult to study with fMRI.
