Research on memory networks suggests that the amygdala has increased centrality and connectivity with other brain regions, including the retrosplenial cortex, thalamus, and hippocampus. Studies have explored various aspects of memory, including temporal context, neural synchronization, and the role of the hippocampus in retrieval and interference. The findings appear to be related to the functioning of brain networks involved in memory, although the specific focus and implications of the research vary across studies.
