Final answer:
The medulla oblongata is not directly involved in memory as it primarily regulates vital bodily functions. Instead, areas like the prefrontal cortex and hippocampus are involved in memory processes. The correct option is B) medulla oblongata
Step-by-step explanation:
The structure that is probably NOT directly involved in memory among the options given is the medulla oblongata. The medulla oblongata is primarily involved in regulating vital body functions, such as breathing, heart rate, and blood pressure, rather than in memory formation or recall.
Contrarily, the prefrontal cortex is associated with higher cognitive functions including working or active memory. The hippocampus plays a critical role in the consolidation of short-term memories to long-term memory and is a part of the medial temporal lobe, which is crucial for memory storage.
Additionally, the thalamus acts as a relay station for information going to the cerebral cortex, which includes some aspects of memory processing. However, the direct involvement of the medulla oblongata in memory is not supported by the existing understanding of its functions. The correct option is B) medulla oblongata
