“…1 Milsum, 1970), Walsh (1966) has shown that jolting movements applied to the body tend to be substantially filtered by body and neck dynamics. Moreover, at frequencies on the order of 100 Hz and above, the pulse code modulation method employed by these brain-stem neurones could hardly transmit the information efficiently (Lee & Milsum, 1971) Goldberg & Fernandez (1971) and Fernandez & Goldberg (1971) have demonstrated the introduction of a 'lead' term into the primary afferent neural response of the monkey to rotational oscillations between about 1 and 8 Hz. Furthermore, the increased gain associated with this phenomenon may well be responsible for the increase of gain in the vestibulo-ocular reflex of man observed by Benson (1970) This would imply very small angular deflexions of the cupula during head movements.…”

SUMMARY1. The neural response of semicircular canal-dependent units in the vestibular nuclei of cats has been examined over a frequency range of sinusoidal rotation extending from 0 004 to 09 Hz.2. Frequency-response analysis indicates that, over the range examined, the information contained in the neural signal received by the brain stem was similar to that expected from the mechanical endorgan.3. Over the experimental frequency range, the relation between neural response and mechanical stimulus was found to be dominated by a single time constant of about 4 sec, such that two response regions can be defined above and below a stimulus frequency of W rad/sec (

Peripheral sensory and motor systems may be characterized by models consisting of multiple parallel convergent pathways, each described by the same set of equations, but having different parameter values in each path. Such models, although deterministic, are best analyzed using a statistical approach, which is illustrated here by analysis of several simple multipath models composed of linear dynamic elements and static non-linear elements. Relationships between instantaneous means of signals at different points in such systems are used to show that a multipath system can exhibit behaviour which would not be expected from observations of individual pathways. Mechanisms for linearization of static nonlinearities are briefly described. Important implications for neurophysiologists are discussed.
