“…Many morphological data have been measured in this plane by Cabanis et al using computerized tomography in 1033 normal adults aged 14 to 80 years 10 . Furthermore, this plane can be used for reproducible head orientation in space, making inter-species comparisons possible 10 59 . The NOP is defined as the plane which, in primary position of gaze (looking straight ahead in the distance), contains the centre of the crystalline lenses, optic discs, and optic foramina 8 9 10 .…”

While convergent, the human orbit differs from that of non-human apes in that its lateral orbital margin is significantly more rearward. This rearward position does not obstruct the additional visual field gained through eye motion. This additional visual field is therefore considered to be wider in humans than in non-human apes. A mathematical model was designed to quantify this difference. The mathematical model is based on published computed tomography data in the human neuro-ocular plane (NOP) and on additional anatomical data from 100 human skulls and 120 non-human ape skulls (30 gibbons; 30 chimpanzees / bonobos; 30 orangutans; 30 gorillas). It is used to calculate temporal visual field eccentricity values in the NOP first in the primary position of gaze then for any eyeball rotation value in abduction up to 45° and any lateral orbital margin position between 85° and 115° relative to the sagittal plane. By varying the lateral orbital margin position, the human orbit can be made “non-human ape-like”. In the Pan-like orbit, the orbital margin position (98.7°) was closest to the human orbit (107.1°). This modest 8.4° difference resulted in a large 21.1° difference in maximum lateral visual field eccentricity with eyeball abduction (Pan-like: 115°; human: 136.1°).

Tomodensitometric examinations of the stereotaxic anatomy of the bovine intrameningeal spacesThe head of a Holstein cow was selected from seven available ones in order to produce a series of tomodensitometric transverse and sagittal sections according to Horsley-Clarke. These sections make it possible to show the stereotaxic topography of the intrameningeal spaces (Sinus epidurales and Cisternae arachnoideales) in Bos taurus.The discussion includes suggestions for new terms for three of the spaces -Sinus condylaris, Cisterna cerebrocerebellaris and Cisterna basilaris.
