Final answer:
The Amygdala and Hippocampus are both considered primary memory centers in the brain, involved in emotion regulation and all aspects of declarative and episodic memory formation, respectively.
Step-by-step explanation:
Among the options provided, B. Amygdala, Hippocampus are both considered primary memory centers in the brain. These two structures are part of the medial temporal lobe and are integral to various types of memory processing. The amygdala is vital for the regulation of emotions and plays a significant role in how memories are stored, particularly those associated with emotional arousal (e.g., fear and fear memories). The hippocampus is associated with declarative and episodic memory, as well as recognition memory, and is crucial for the consolidation of these types of memories into long-term memory. Together, these structures function to encode, consolidate, and retrieve memories that are essential for learning and navigation in complex environments.
