Final answer:
The cerebrum, especially the cerebral cortex, is the center for intellectual functions such as judgement, memory, and problem solving. Among the cerebral structures, the hippocampus, located in the medial temporal lobe, is crucial for memory functions.
Step-by-step explanation:
The cerebrum is the part of the brain that is involved in intellectual functions such as judgement, memory, and problem solving. More specifically, it is the cerebral cortex, a thin layer of gray matter on the outside of the cerebrum, that is associated with these higher mental functions. The mental status exam evaluates cognitive abilities that are attributed to specific regions of the cortex, which include primary sensory or motor areas, association areas, and multimodal integration areas. Functions like attention, memory, language, speech, sensation, judgement, and abstract reasoning are all managed by this complex structure. In the case of memory, the hippocampus, which is part of the medial temporal lobe and adjacent cortex, plays a significant role alongside structures like the amygdala.
The correct answer to the question is option 2) Cerebrum.
