| OVERVIEW |
The Human atlas is a spatially accurate, high-resolution three-dimensional (3D) volume of brain anatomy from cryosectioned whole human head. The head of a 76 year old female cadaver was cryosectioned on a heavy duty cryomacrotome (PMV, Stockholm Sweden) modified for quantitative digital image capture. Data were placed into the Talairach coordinate system to create a volume of brain anatomy for atlas reference. The spatial resolution of the original digitized images provided sufficient anatomic detail to clearly delineate gray and white matter and neural structures, including major fiber pathways, subthalamic nuclei, and laminae. Animation proved useful in the conveyance of system anatomy as structures are shown traversing through the neuroaxis. Postmortem cryosectioning paired with this computerized presentation allowed the complete 3D volume data to be distributed and shared as an educational, clinical, and research resource. |

|
(Requires Java Plug-in) The Human 2D Atlas viewer is a web-based 2D slice viewer that visualizes single slices at a time.
The user selects a modality and an orientation from the panels on the left. At the bottom of the viewer is a graphical representation of the human brain with a bar through it and a thumbnail image. Dragging the bar will scroll through the images, and releasing it will update the main panel on the right with a high-resolution image of the selected slice. |
