The thickness at the left and right of the bregma (away from the thickness of the plain cranial vault) showed the same age-related trend between the two sexes: a slight increase from young adulthood to mid-adulthood followed by a significant decrease from mid-adulthood to the oldest age.
The point of the syringe needle was positioned symmetrically in the central part of the substantia nigra pars compacta and extended from 4.80 to 5.16 mm posterior to bregma (Figure 1).
Sections were collected at + 1.2 mm to -1.2 mm from the bregma according to the coordinates of Slotnick and Leonard [29], and seven coronal sections were analyzed from each animal using a microscope with a 20x objective.

The POA-AHA was located using the bregma coordinates from the atlas as the reference (A-P, 0.679 to 0.628; lateral, 0.06; and vertical, 0.86) [16], following a previously described protocol [9-12].
The coordinates of the ICV cannula implantation were 0.8 mm anterior to posterior (AP) bregma, 1.8 mm midline to lateral (ML), and 4 mm dorsal to ventral (DV) dura.

These were basal ganglia (bregma + [approximately equal to] 0.14 mm), thalamus (bregma - [approximately equal to] 1.46 mm), posterior hippocampus (bregma - [approximately equal to] 2.92 mm), and anterior cerebellum (bregma - [approximately equal to] 6.00 mm), on paraffin sections stained with hematoxylin and eosin or probed with the 3F4 antibody to the prion protein (PrP) (1:1,000-1,400) (24).
Fusion of this suture commences at the anterior fontanelle i.e., bregma and terminates at nasion.
The general location for injection is 1 mm anterior to bregma and 1 mm lateral to the sagittal suture on the right side.
The area of the lateral ventricles (approximate bregma range: 1.10-0.38 mm) and aqueduct of Sylvius (approximate bregma range: -3.88 to -4.84 mm) was determined by tracing the outline of the area of interest in at least four adjacent sections of slide-mounted brain tissue using Neurolucida (MBF, Villiston, VT).
