Downloads for RH12 (Sagittal), 1 in 20 series
This series of sections has been prepared from a celloidin-embedded
rhesus (Macaca mulatta) brain, serially sectioned at a thickness of
40 microns in the parasagittal plane and stained by the Nissl stain.
The series of sections, as for the frontal series, was scanned at 2,666
D.P.I., and the sections in the series presented here are at
approximately 800 micron intervals through the brain. Numbers at top
left indicate the exact position in mm. The sections contain fiduciary
marks obtained by inserting electrodes into the brain from its lateral
side at defined stereotaxic coordinates before perfusing the animal.
Three horizontal tracks were made at Horsley-Clarke coordinates:
AP zero, horizontal +15mm; AP +25mm, horizontal +15; AP +25mm,
The images are both in JPG and PSD file formats. The JPG images are
much smaller in file size (and thus quicker to download) and can be
viewed in your browser, but do not possess layers. The PSD images are
best opened in Photoshop� in order to preserve the capacity to turn the
layers on or off. Each consists of four layers: a layer containing the
image of the histological section, registered to its neighbors on the
basis of the fiduciary marks; a layer consisting of two vertical lines
at AP zero and AP+25mm, and two horizontal lines at horizontal +15mm
and +25mm; a layer of type showing the position of the section (in mm)
relative to the midline and labeling of key structures using a standard
abbreviation system; a template layer giving the outlines of the section
and of the larger grey and white matter components.
We are particularly interested in obtaining opinions about how best to
parcellate further many of the structures identified, especially the
cerebral cortex and brainstem reticular formation. Please let us have
your comments at jmstone-at-ucdavis.edu.
