The orientation of the cervical vertebral column in unrestrained awake animals. I. Resting position.
P. P. Vidal,W. Graf,A. Berthoz +2 more
TL;DR: The vertical orientation of the cervical vertebral column is interpreted to provide a stable and energy saving balance of the head, and the atlantooccipital and cervico-thoracic junctions are predominantly involved, while the entire cervical column largely preserves its intrinsic configuration.

Skeletal geometry underlying head movements.
TL;DR: The stereotyped resting posture adopted by seven of nine studied vertebrate species is introduced and the number of degrees of freedom of the articulations of the cervical vertebral column is reduced, contributing to the fact that orienting movements when studied by cineradiography are in fact stereotyped and confined to certain planes of space, corroborating Bernstein' hypothesis.

Functional anatomy of the head-neck movement system of quadrupedal and bipedal mammals.
TL;DR: This biomechanical investigation quantified the range of motion of the different articulations of the head-neck ensemble in man, monkeys, cats, rabbits and guinea pigs and hypothesized that different mechanical requirements relating to the influence of gravity have caused the observed differences between the investigated bipedal and quadrupedal mammals.

The Orientation of the Cervical Vertebral Column in Unrestrained Awake Animals (Part 1 of 2)
TL;DR: A stereotyped resting posture of the head-neck arrangement in a number of vertebrates is demonstrated: the cervical vertebral column is oriented vertically to form one portion of the partia.

Second-order vestibular neuron morphology of the extra-MLF anterior canal pathway in the cat
TL;DR: The morphology of individual excitatory second-order neurons of the anterior semicircular canal system that course outside the MLF to the oculomotor nucleus are determined and are thought to be involved exclusively in eye movement control.
