Although calcium waves have been widely observed in glial cells, their occurrence in vivo during behavior remains less understood. Here, we investigated the recruitment of glial cells in the hindbrain and spinal cord after acousto‐vestibular (AV) stimuli triggering escape responses using in vivo population calcium imaging in larval zebrafish. We observed that gap‐junction‐coupled spinal glial network...
Parallel fiber synapses in the cerebellum express a wide range of presynaptic receptors. However, presynaptic receptor expression at individual parallel fiber synapses is quite heterogeneous, suggesting physiological mechanisms regulate presynaptic receptor expression. We investigated changes in presynaptic GABAB receptors at parallel fiber‐stellate cell synapses in acute cerebellar slices from juvenile...
Cerebrospinal fluid contacting neurons (CSF-cNs) are found around the central canal of all vertebrates. They present a typical morphology, with a single dendrite that projects into the cavity and ends in the CSF with a protuberance. These anatomical features have led to the suggestion that CSF-cNs might have sensory functions, either by sensing CSF movement or composition, but the physiological mechanisms...
• The brainstem is a major site of integration for autonomic information from neurones, blood and cerebrospinal fluid (CSF). Signals exchange from the CSF is limited by the ependymocytes forming the brain cavities. However neurones contacting the CSF (CSF‐cNs) are thought to integrate those signals.
• Using immunohistochemical and electrophysiological approaches, we characterise in the brainstem,...
