The circuit involved in forming new autobiographical memory and declarative/explicit memory is which?

Forming autobiographical and declarative (explicit) memories depends on a limbic loop that coordinates encoding and consolidation across medial temporal and limbic structures. This pathway starts with the hippocampus encoding episodic details, then projects via the fornix to the mammillary bodies and onward through the mammillothalamic tract to the anterior thalamic nuclei, looping through the cingulate gyrus and back toward the entorhinal cortex and hippocampus. This coordinated circuit is classically known as the Papez circuit, and it supports the creation of new declarative memories that you can consciously recall. The amygdala plays a modulatory role, especially for emotionally charged memories, but it is not the primary route for forming autobiographical or declarative memories. The dorsal visual stream and ventral visual stream are specialized for visual processing—the former for spatial relations and action ("where/how"), the latter for object identification ("what")—and do not by themselves underlie the formation of autobiographical memory.
