OBJECTIVES To test the previous findings of Enright that disparity-induced vertical vergence is mediated primarily by the oblique muscles, and to relate this normal eye movement pattern to the eye movement pattern seen in subjects with dissociated vertical deviation. METHODS Sixteen normal volunteers underwent 55 measurements of the cycloversion associated with prism-induced vertical vergence...

Perception of movement in acoustic space depends on comparison of the sound waveforms reaching the two ears (binaural cues) as well as spectrotemporal analysis of the waveform at each ear (monaural cues). The relative importance of these two cues is different for perception of vertical or horizontal motion, with spectrotemporal analysis likely to be more important for perceiving vertical shifts...

OBJECTIVES To test the hypothesis that reducing vertical center of mass (COM) displacement will lower the metabolic cost of human walking. To examine changes in joint work associated with increasing and decreasing vertical COM movement during gait. DESIGN Randomized repeated measures. SETTING Human Neuromechanics Laboratory, University of Michigan. PARTICIPANTS Able-bodied subjects (N=10)...

This paper discusses issues including tongue position, tongue movement space, constraint etc. of Mongolian word-initial consonants. The experimental result shows that word-initial consonant tongue horizontal movement space is constrained by constriction position and is in conformity with the rule that front consonant leads to smaller tongue movement space; higher consonant leads to smaller tong...

An intensive experimental investigation was conducted to study the effect of vertical tail, single and twin (with different cant angles) on the flow field and the corresponding aerodynamic forces and moments of a model of a fighter A/C. Aerodynamic forces under different flight conditions and different vertical tail settings were measured in a supersonic wind tunnel. Furthermore, effects of ver...

DOS Times Vol. 12, No. 3 September, 2006 Dissociated Vertical Deviation (DVD) is one of the least understood forms of strabismus. It was first described by Stevens as double vertical strabismus, other common names given to this anomaly are, Alternating hyperphoria (Crone), Anaphoria / anatropia (Stevens), Periodic vertical squint (Anderson), Strabismus sursoadductorius (Cords). The term "Dissoc...

A patient affected by an ischaemic lesion of the right medial thalamic nucleus presented with a uniocular dissociation of upward vertical saccades and pursuit movement, with absent upward vertical saccades in the left eye. Clinical observations were confirmed by magnetic field scleral search coils analysis. During the vertical eye movement the patient denied any diplopia, thus suggesting a tran...
