hippocampal formation
Hippocampus (proper) plus dentate gyrus and subiculum[definition derived from NIF comments and ontology alignment]. Every claim on this page comes from the Leumas anatomy graph and carries its source.
What the hippocampal formation is
Hippocampus (proper) plus dentate gyrus and subiculum[definition derived from NIF comments and ontology alignment]. The atlas records it as a nerve at the organ scale in the human body.
Where the hippocampal formation is
It sits within the nervous system. Not positioned individually. Drawn inside the structure this dataset says contains it — the containment is asserted, the exact spot within it is not.
What the hippocampal formation connects to
The atlas records 16 typed relationships for it, across 4 kinds of connection. part of cerebral cortex and telencephalon.
Supply and innervation
This dataset asserts no arterial supply, venous drainage or innervation for the hippocampal formation. Only a minority of structures carry those edges here, so an empty answer means nothing has been recorded — not that there is nothing to record.
Also called
Also recorded as hippocampus (Crosby), hippocampus, archipallium, formatio hippocampi, major hippocampus and primal cortex, and 1 more. Searching any of those names reaches this page.

Questions
Where is the hippocampal formation?
It sits within the nervous system. Not positioned individually. Drawn inside the structure this dataset says contains it — the containment is asserted, the exact spot within it is not.
What does the hippocampal formation connect to?
Part of: cerebral cortex and telencephalon.
Is the hippocampal formation the same in other species?
Leumas holds the same relationship vocabulary for every species it carries, so where another dataset records this structure you can put the two side by side on /compare.
