Hippocampal Efferents Reach Widespread Areas of Cerebral Cortex and Amygdala in the Rhesus Monkey

Key Points

• This research aims to elucidate the pathways through which the hippocampal subiculum projects to various brain regions in primates.
• Investigated the intrinsic hippocampal efferents originating from the subiculum
• Mapped connections to the medial frontal cortex, caudal cingulate gyrus, parahippocampal area, and amygdala
• Examined subcortical projections to the septum and diencephalon
• Identified that the subiculum sends efferents to the medial frontal cortex and caudal cingulate gyrus
• Established connections to the parahippocampal area and amygdala
• Documented subcortical connections to the septum and diencephalon
