Over the past decades, the new opportunity of space flights has revealed the importance of gravity as a mechanical constraint for terrestrial organisms as well as its influence on the somatosensory system. The lack of gravitational reference in orbit

The electrophysiological development of hair cells between birth and the eight postnatal day (P8) was studied in the utricular macula of rats gestated in nest boxes mounted upon a centrifuge, subjecting the animals to a gravitational force of 2G. Who

The properties of the vestibular Na+-Ca2+ exchanger in mammalian type I vestibular sensory cells were studied using fura-2 fluorescence and immunocytochemical techniques. In the absence of external Na+, the activation of Na+-Ca2+ exchange in reverse

Ionic currents and the voltage response to injected currents were studied in an acutely dissected preparation of the rat utricle between birth and postnatal day 12 (PN12). Based upon morphological criteria, the sensory cells examined were divided int

The existence of voltage-sensitive Ca2+ channels in type I vestibular hair cells of mammals has not been conclusively proven. Furthermore, Ca2+ channels present in type II vestibular hair cells of mammals have not been pharmacologically identified. F

The variations of intracellular free calcium concentration ([Ca2+]i) were recorded on-line from guinea-pig isolated vestibular sensory cells using a fura-2 fast fluorescent photometry system, during mechanical displacements of the hair bundle. Repeti

The resting free calcium level was measured in 128 isolated mammalian vestibular sensory cells using the calcium-sensitive dye fura-2. Iontophoresis was used to apply short, localised and limited pulses of K+ which evoked dynamic changes in intracell

The aim of this study was to investigate whether an altered gravitational environment affected the phenotype of vestibular hair cells during maturation. We developed, using an automated incubator, a 3D culture of utricles from newborn rats. These cul

Isolated guinea pig type I vestibular hair cells were voltage clamped at HP-110 mV in whole cell clamp configuration and depolarized up to +20 mV. Increasing depolarizations elicited large outward currents. These currents were replaced, in cesium-loa
