Question

Research suggests that the consolidation of memories depends on activity in the: A. cerebellum. B. prefrontal cortex. C. medial temporal lobe. D. corpus callosum.

Short answer

Answer: C. medial temporal lobe

Step-by-step solution

Understanding the cerebellum

The cerebellum is located at the base of the brain and plays a crucial role in motor control, balance, coordination, and maintaining posture. While it does have some cognitive functions, it is not directly related to the consolidation of memories.

Understanding the prefrontal cortex

The prefrontal cortex is located at the front of the brain and is responsible for executive functions, which include planning, decision-making, emotional regulation, and working memory. Although it plays a role in memory, it is not the primary region for memory consolidation.

Understanding the medial temporal lobe

The medial temporal lobe is located near the center of the brain and is responsible for the consolidation of memories, particularly the formation of long-term memories. This region includes the hippocampus, which is crucial for producing and retrieving memories.

Understanding the corpus callosum

The corpus callosum is a band of neural fibers located in the center of the brain, connecting the two cerebral hemispheres. Its primary function is to facilitate communication between the left and right sides of the brain, but it is not directly involved in the consolidation of memories.

Revealing the correct answer

Based on the functions of each brain region, it is now evident that the correct answer is C. medial temporal lobe, as it is responsible for the consolidation of memories.
