Intrinsic membrane properties of vertebrate vestibular neurons: Function, development and plasticity
TLDR
In vitro studies indicate that medial vestibular nucleus neurons are of two major subtypes (A and B), which differ in their spike shape and after-hyperpolarizations, and membrane properties of MVN neurons show rapid and long-lasting plastic changes after deafferentation, which may serve to maintain their level of activity and excitability after the loss of afferent inputs.

Variability in the control of head movements in seated humans: a link with whiplash injuries?
TLDR
The response of floppy subjects appeared to be maladaptive and likely to increase the risk of whiplash injury during motor vehicle accidents, and the adoption by the central nervous system of an extrinsic, ‘allocentric’ frame of reference instead of an intrinsic, “egocentric” one may be instrumental for the selection of the stiff strategy. Expand
Long-term plasticity of ipsilesional medial vestibular nucleus neurons after unilateral labyrinthectomy.
TLDR
It is shown that long-term vestibular compensation involves major changes in the membrane properties of Vestibular neurons on the deafferented side, including changes in active conductances compensated for the loss of excitatory afferents. Expand
Oscillatory and intrinsic membrane properties of guinea pig nucleus prepositus hypoglossi neurons in vitro.
TLDR
The experiments reported here show that all PHN neurons (PHNn) show marked phasic behavior, which is highly oscillatory in approximately 25% of the population, and suggest that the PHNn have specific intrinsic properties that, in conjunction with network interconnections, enhance the persistent neural activity needed for their function.

Central vestibular networks in the guinea-pig: functional characterization in the isolated whole brain in vitro
TLDR
The isolated, in vitro whole brain of guinea-pig was used to assess some of the main physiological and pharmacological properties of the vestibulo-ocular pathways in this species, and recordings from abducens and oculomotor complexes confirmed the existence of strong bilateral, disynaptic excitatory and inhibitory inputs from vestibular afferents to motoneurons of extraocular muscles, which contribute to generation of the Vestibular-ocular reflex.

Readers’ use of source information in text comprehension
TLDR
Examination of the role of discrepancy on readers’ text processing of and memory for the sources of brief news reports found enhanced memory for source–content links for discrepant stories even when intersentential connectors were absent, and regardless of the reading goals. Expand
Resonance of spike discharge modulation in neurons of the guinea pig medial vestibular nucleus.
TLDR
Differences in the modulation of spiking rates were observed between neurons with a single, prominent after hyperpolarization (AHP, type A neurons) and cells with more complex AHPs (type B neurons), which suggests that type B neurons are like low-pass filters that are well suited for the resting tonic activity of the vestibular system.

Medial vestibular nucleus in the guinea-pig: histaminergic receptors
TLDR
Using a variety of agonists and antagonists of histamine receptors (H1, H2 and H3), it is concluded that effects are mediated by H2 receptors. Expand
Safety and efficacy of repetitive transcranial magnetic stimulation in the treatment of obsessive-compulsive disorder: A review
TLDR
Three target areas have already been selected of which the supplementary motor area in particular and the orbitofrontal cortex seem to be the most promising in terms of potential efficacy and could more accurately be targeted with the help of neuronavigational techniques. Expand
Modification of the pacemaker activity of vestibular neurons in brainstem slices during vestibular compensation in the guinea pig
TLDR
Results show that deprivation of the vestibular neurons of their labyrinthine input caused a change in the deprived neurons themselves, and suggest that an increase in pacemaker activity might be a factor responsible for the restoration of spontaneous activity in the vestIBular neurons after labyrinthectomy.
