Labyrinth Chaos
A particularly simple and mathematically elegant example of chaos in a threedimensional flow is examined in detail. It has the property of cyclic symmetry with respect to interchange of the three orthogonal axes, a single bifurcation parameter that governs the damping and the attractor dimension over most of the range 2 to 3 (as well as 0 and 1) and whose limiting value b = 0 gives Hamiltonian ...
متن کاملLabyrinth and Equilibrium
1. A dogfish from which all six ampullae have been removed maintains its equilibrium; the righting reactions occur promptly; compensatory movements of the eyes occur in response to rotations in all planes except the horizontal; the compensatory position of the eyes is retained if the animal is held in an abnormal position. Both the static and dynamic functions of equilibrium continue, therefore...
متن کاملStudy of congenital nystagmus: optokinetic nystagmus.
A severe defect of optokinetic nystagmus (OKN) was found in 46 patients with congenital nystagmus. Abnormal patterns of OKN, such as superimposition of pendular oscillations on the optokinetic slow component and inversion of OKN, were observed. Optokinetic gain (eye movement velocity/drum velocity) was decreased compared to that in normal subjects, and optokinetic after-nystagmus, or transient ...
متن کاملLatent nystagmus: vestibular nystagmus with a twist.
BACKGROUND Latent nystagmus is a horizontal binocular oscillation that is evoked by unequal visual input to the 2 eyes. It develops primarily in humans with congenital esotropia. OBJECTIVE To investigate the interrelationship between latent and peripheral vestibular nystagmus and their corollary neuroanatomical pathways. METHODS Examination of subcortical neuroanatomical pathways producing ...
متن کاملMiners' Nystagmus an Investigation of Miners' Nystagmus
As an ophthalmic and aural surgeon practising in a colliery area, I meet many cases of miners' nystagmus in miners' hospitals, and mnany cases are referred to me by colliery companies and the South Wales Miners' Federation. I feel I have some advantage over some previous investigators, I am both an ophthalmic and an aural surgeon; I have not read any literature which states that the inner ear h...
