Abstract:

1. Properties of nucleus incertus (NIC) neurons projecting to the cerebellar flocculus were studied in alert cats by using chronic unit and eye movement recording and antidromic activation. Projection of these neurons onto the flocculus was verified with retrograde transport of horseradish peroxidase after injections in the flocculus. 2. Bipolar stimulation electrodes were implanted into the "middle" zone of each flocculus because this zone is known to be involved in the control of horizontal eye movements. The dorsomedial aspect of the pontine tegmentum was explored with microelectrodes durin

Iris flocculi, a type of hereditary iris pigment epithelial cyst, have been reported in association with smooth muscle α-2 actin (ACTA2) gene as the causative gene of familial thoracic aortic aneurysm and dissections (FTAAD). The purpose of the report was to examine morphological changes in the shape of flocculi and iris features over time by comparing infants to adults with FTAAD combined with iris flocculi. A Japanese family with FTAAD and bilateral iris flocculi and the Arg149Cys gene mutation was included. A slit-lamp photograph and anterior segment optical coherence tomography (AS-OCT) we

Abstract:

The authors describe two cases of papillary margin flocculi in the children and the results of their successful laser-assisted treatment. It was shown that papillary margin flocculi can obstruct the area of the pupil and thereby cause obscurity and visual impairment in the children. The application of a YAG-laser for the drainage and destruction of papillary margin flocculi measuring up to 4-6 mm makes it possible to significantly reduce the size of the flocculi. Elimination of their protrusion into the pupil area clears the optically significant region and thereby improves visual acuity witho

Abstract:

Abstract It is generally assumed that flocs grow according to the following model: primary particles form compact flocculi which assemble themselves into microflocs. Microflocs bind together to form floc aggregates. The main difference between flocculi, microflocs and floc aggregates is their structure. Porosity can be used to indicate differences in this structure. The objective of this study was to establish whether alum flocs disperse into floc components that represent different structures, as indicated by different porosities. Alum coagulation floes were broken up with increasing amounts

If the FRN phase lead is produced by signals from the flocculus, then the Purkinje cells should functionally lead the FRNs.

Also the reaction constant, the destabilization factor and the growing constant of the coagulation and flocculation process are calculated.

The vestibuloocular reflex (VOR) generates compensatory eye movements to stabilize visual images on the retina during head movements. The amplitude of the reflex is calibrated continuously throughout life and undergoes adaptation, also called motor learning, when head movements are persistently associated with image motion. Although the floccular-complex of the cerebellum is necessary for VOR adaptation, it is not known whether this function is localized in its anterior or posterior portions, which comprise the ventral paraflocculus and flocculus, respectively.

This adaptation most often involves morphological changes such as pseudofilaments, biofilm formation, or cell aggregation in the form of flocs.

This ability is conferred by specialized surface proteins called flocculins, which are encoded by the FLO genes family in this yeast species.

Abstract:

We recorded the simple-spike (SS) firing of Purkinje cells (PCs) in the floccular complex both during normal pursuit caused by step-ramp target motions and after learning induced by a consistently timed change in the direction of target motion. The encoding of eye movement by the SS firing rate of individual PCs was described by a linear regression model, in which the firing rate is a sum of weighted components related to eye acceleration, velocity, and position. Although the model fit the data well for individual conditions, the regression coefficients for the learned component of firing ofte

Abstract:

AbstractThe cerebellar cortex has a fundamental parasagittal organization that is apparent in the physiological response properties of Purkinje cells (PCs) and the expression of several molecular markers such as zebrin II (ZII). ZII is heterogeneously expressed in PCs such that there are sagittal stripes of high expression [ZII immunopositive (ZII+)] interdigitated with stripes of little or no expression [ZII immunonegative (ZII−)]. Several studies in rodents have suggested that climbing fiber (CF) afferents from an individual subnucleus in the inferior olive project to either ZII+ or ZII− str

Abstract:

Mutation of the Cacna1a gene for the P/Q (CaV2.1) calcium channel invariably leads to cerebellar dysfunction. The dysfunction has been attributed to disrupted rhythmicity of cerebellar Purkinje cells, but the hypothesis remains unproven. If irregular firing rates cause cerebellar dysfunction, then the irregularity and behavioral deficits should covary in a series of mutant strains of escalating severity. We compared firing irregularity in floccular and anterior vermis Purkinje cells in the mildly affected rocker and moderately affected tottering Cacna1a mutants and normal C57BL/6 mice. We also

Abstract:

Extracellular unit spikes were recorded in and around the Y-group nucleus in the anesthetized cat. Target (T) neurons of floccular caudal zone inhibition were identified by observing cessation of their spontaneous discharges following stimulation of the floccular caudal zone. The axonal trajectories of the T neurons to the rostral brain stem were studied by observing the antidromic responses of single neurons during systematic tracking with a stimulating microelectrode in the brain stem. The axons of the T neurons pass through a region closely ventral to the lateral part of the brachium conjun

Abstract:

The article presents the results of studying physical and mechanical properties of thickened concentration tailings, as well as regularities in their changes during the dumping process in mined-out spaces of open-pits. The necessity of experimental studies is explained by the existing discrepancy between the parameters of the artificial hydraulic deposition of soils and the design solutions, in particular, the spreading angles, the lack of a ponding zone created within the rock mass body, as well as the insignificant influence on the intakes of the dewatering plant.

Abstract:

The caudal dorsal cap (dc) of the inferior olive is involved in the control of horizontal compensatory eye movements. It provides those climbing fibers to the vestibulocerebellum that modulate optimally to optokinetic stimulation about the vertical axis. This modulation is mediated at least in part via an excitatory input to the caudal dc from the pretectal nucleus of the optic tract and the dorsal terminal nucleus of the accessory optic system. In addition, the caudal dc receives a substantial GABAergic input from the nucleus prepositus hypoglossi (NPH). To investigate the possible contributi

Abstract:

1. The three -dimensional, binocular eye movements evoked by electrical microstimulation of the cerebellar flocculus of alert, pigmented rabbits were recorded using the scleral search coil technique. The components of these eye movements were obtained in reference to an orthogonal coordinate system consisting of a vertical axis and two horizontal axes at 45 degrees and 135 degrees azimuth. The azimuth coordinate was taken to increase to both sides from the 0 degrees reference in the direction of the nose. 2. Eye movements were evoked most readily by stimulation (0.2 -ms pulses at 200 Hz for 1
