Abstract: The hippocampal formation plays a pivotal role in spatial cognition and episodic memory, while the amygdala is essential for adaptive fear conditioning. We have developed a brain reference architecture (BRA) data format by integrating "TM24Amygdala_ver4" (based on "YM24Amygdala") and "TN24HippocampalFormation" BRA data. This BRA data expands on previous BRA models by incorporating new brain information flow (BIF) that captures the connections between the hippocampus and amygdala. The constructed BIF provides a basis for defining higher-order functions related to spatial cognition and fear conditioning. These improvements deepen our understanding of the anatomical structure linking these regions and their interconnected functions. The BRA repository provides comprehensive access to these data, supporting further research into the functional and structural relationships between the hippocampal formation and the amygdala. This work not only advances our understanding of each region’s individual role but also provides insights into how their interaction shapes complex cognitive and emotional processes.
