Explanation:

Brain-intact people are more likely to have increased activity in the Left hemisphere when identifying the small letters (A) and increased activity in the Right when identifying the overall pattern (X).

The left hemisphere controls the right part of the body and the right hemisphere controls the left part of the body. The left hemisphere performs functions such as language and logical analysis in which identification of small letters is included. The right hemisphere is however known for its art and creative functions which explains why it is good at identifying overall patterns.
