Responses of vestibular-only translation sensitive (VOTS) neurons in vestibular nuclei of two squirrel monkeys were studied at multiple frequencies to three-dimensional translations and rotations. A novel frequency-dependent spatiotemporal analysis examined in each neuron whether complex models, with unrestricted response dynamics in three-dimensional (3D) space, provided significantly better fits than restricted models following simple, cosine rule. Subsequently, the statistically selected… 
Responses of non-eye movement central vestibular neurons to sinusoidal horizontal translation in compensated macaques after unilateral labyrinthectomy.
A decrease in sensitivity, increase in threshold, and alteration in orientation of best responses in the vestibular nuclei after UL is found, and the phase relationship of the best neural response to translational stimulation changed with UL.
Adaptation of spatio‐temporal convergent properties in central vestibular neurons in monkeys
STC behavior is also linked to the neural network responsible for localized contextual learning during gravity‐dependent adaptation and is a property of weights of the regular and irregular vestibular afferent inputs to central Vestibular neurons which appear and/or disappear based on stimulus frequency and orientation adaptation.
Transformation of spatiotemporal dynamics in the macaque vestibular system from otolith afferents to cortex
It is suggested that the first synapse represents a key processing element in Vestibular pathways, robustly shaping how self-motion is represented in central vestibular circuits and cortical areas.
Convergence of linear acceleration and yaw rotation signals on non-eye movement neurons in the vestibular nucleus of macaques.
Nonlinear integration leading to maximum response amplitude when the timing and direction of peak rotational and translational responses are coincident is demonstrated; this results are similar to those reported for other forms of multisensory integration, such as audio-visual integration in the superior colliculus.
Neuronal thresholds and choice-related activity of otolith afferent fibers during heading perception
It is found that afferent fibers have similar discrimination thresholds as central cells, and the most sensitive fibers have thresholds that are only twofold or threefold greater than perceptual thresholds, which may reflect the fact that otolith afferent responses are poorly suited for driving heading perception because they fail to discriminate self-motion from changes in orientation relative to gravity.
Diversity of vestibular nuclei neurons targeted by cerebellar nodulus inhibition
Electrical stimulation of the cerebellar nodulus and ventral uvula decreases the time constant of the horizontal vestibulo‐ocular reflex during yaw rotation and projections of the nodulus/ventral Uvula to both eye movement‐and non‐eye movement‐sensitive vestibular nuclei neurons suggest a role in both eyemovement generation and vestIBulo‐spinal or thalamo‐cortical systems.
The Neurogoniometry: Applied Optical Analysis for Neural Structure Directogramm / Radiation Pattern Measurements
The possibility of constructing a dynamic neurogoniometer based on a rotary mechanotronic system controlled by stepper motors and a number of controlled reflectors on the galvanometric scanners is


Responses of monkey vestibular-only neurons to translation and angular rotation.
Single-unit recordings were obtained from central vestibular neurons in three monkeys during passive head movements and predicted neurons with discharge patterns similar to those of low- and high-sensitivity neurons.
Vestibular convergence patterns in vestibular nuclei neurons of alert primates.
Contrary to primary otolith afferents and otolith-only central neurons that respond equivalently to tilts relative to gravity and translational movements, approximately one-third of the otolith + canal cells seem to encode a true estimate of the translational component of the imposed passive head and body movement.
Encoding of head acceleration in vestibular neurons. I. Spatiotemporal response properties to linear acceleration.
Neurons were functionally identified according to their semicircular canal input on the basis of their responses to angular head rotations around the yaw, pitch, and roll head axes and their spatiotemporal response properties to sinusoidal stimulation with pure linear acceleration were quantified.
Spatiotemporal processing of linear acceleration: primary afferent and central vestibular neuron responses.
The response dynamics of central otolith neurons suggest that the approximately 90 degrees phase lags observed at low frequencies are not the result of a neural integration but rather the effect of nonminimum phase behavior, which could arise at least partly through spatiotemporal convergence.
Three-dimensional organization of otolith-ocular reflexes in rhesus monkeys. III. Responses To translation.
The three-dimensional (3-D) properties of the translational vestibulo-ocular reflexes (translational VORs) during lateral and fore-aft oscillations in complete darkness were studied in rhesus monkeys and suggest two functionally different frequency bandwidths for the translations.
Spatial properties of central vestibular neurons.
VO and VPS neurons associated with velocity storage receive a broad range of convergent inputs from each portion of the vestibular labyrinth, which could provide the basis for gravity-dependent eye velocity orientation induced through velocity storage.
A model for the characterization of the spatial properties in vestibular neurons
The model satisfactorily fits neuronal responses in three-dimensions and unequivocally demonstrates that the response ellipse formulation is the general approach to describe quantitatively the spatial properties of vestibular neurons.
Spatio-temporal convergence (STC) in otolith neurons
It has been recently demonstrated that some primary otolith afferents and most otolith-related vestibular nuclei neurons encode two spatial dimensions that can be described by two vectors in temporal and spatial quadrature that are characterized by a non-zero tuning ratio.
Responses to head tilt in cat central vestibular neurons. II. Frequency dependence of neural response vectors.
The responses of central vestibular neurons in the decerebrate cat subjected to whole-body tilt were examined as a function both of stimulus orientation (with respect to the cat's head) and
Frequency-Selective Coding of Translation and Tilt in Macaque Cerebellar Nodulus and Uvula
It is shown that NU simple spike (SS) responses also exhibit a frequency dependent selectivity to self-motion (translation) and spatial orientation (tilt), consistent with the notion that N U SS modulation represents an internal neural representation of similar frequency dependencies seen in behavior.
