Question

Recent advances in non-invasive human neuroimaging have provided researchers in the emerging field of social brain science with insights into the workings of consciousness and social cognition. Of special interest is the medial prefrontal cortex (MPFC), a region of the brain associated with memory, fear, and, perhaps, prejudice.

Fears create memories, and those memories appear to be stored in the amygdala. This same region also seems to create memories that counter those fears, though these memories are then stored in the MPFC. Neuroimages show that nerves from the MPFC project into the amygdala, providing the mechanism for suppressing the fear response. As one might expect, rodents with MPFC damage have a decreased ability to deal with certain fears.

MPFC activity also seems to correlate with self-referential judgments and memory. The dorsal MPFC in particular shows heightened activity during introspective mental activity. Interestingly, there is a reduction in ventral MPFC activity when individuals are involved in tasks that demand attention. This indicates that cognitive activity can decrease certain emotional processing. Other differences between these two areas of the MPFC have been noted. The ventral region becomes more engaged when an individual is shown photographs of strangers whose political beliefs—so the viewer is told—are similar to those of the person viewing the photograph, but the dorsal region becomes more active when the photographs are of individuals with whom the viewer does not share the same political perspective.

As long ago as the 19th century, scientists knew that damage to the MPFC interfered with social skills while leaving other mental skills untouched. With our newfound ability to actually observe mental activity in both healthy and impaired individuals without recourse to surgery, we have entered into an area that is sure to provide us with information about ourselves that will prove to be of enormous interest and great usefulness.

According to the passage, it is likely that the memories that allay fears are               .

Answer

Solution: "created and stored in different parts of the brain"

Refer back to the passage to answer this Specific question. According to the 2nd paragraph, the amygdala “creates memories that counter those fears, though these memories are then stored in the MPFC.” "formed in the dorsal and ventral MPFC": No connection is made between specific regions of the MPFC and fears. "related to memories that form prejudices": No connection is made between prejudices and memories that allay fears. "able to be manipulated in rats through neuroimaging procedures": No mention of manipulating rats’ memories is made. Neuroimaging is used for viewing images, not manipulating memories. "affected by tasks that demand attention": Attention-demanding tasks are not mentioned in relation to fears.
