-
A.
perivascular space
A perivascular space is a fluid-filled, microscopic channel that surrounds blood vessels as they pass through the brain or other tissues, facilitating fluid exchange and waste clearance.
-
B.
rostral column
A rostral column is a vertical structural element located toward the front (rostral end) of an anatomical or architectural system, often serving as a support or organizational axis.
-
C.
aperture of the ventricular system
The aperture of the ventricular system is an opening within the brain’s ventricles that allows cerebrospinal fluid to flow between the ventricular cavities and the surrounding subarachnoid space.
-
D.
cortical area
A cortical area is a distinct region of the cerebral cortex characterized by specific cytoarchitecture, connectivity, and functional roles in processing sensory, motor, or cognitive information.
-
E.
median aperture of the fourth ventricle
The median aperture of the fourth ventricle is a midline opening in the roof of the fourth ventricle that allows cerebrospinal fluid to flow from the ventricular system into the subarachnoid space, particularly the cisterna magna.
- F. None of above. chosen
Provenance (1 batch)
The batch behind each pipeline step, in order, with when it ran. Timestamps are batch-level — stages were processed in waves, so the object chain (NER → NED1 → NEDg → NED2) reads in order, but predicate / elicitation batches can sit in a different wave.
