  Primary vestibular neurons are categorized as either regularly or irregularly
firing afferents that use rate and temporal sensory encoding strategies,
respectively. While many factors influence firing in these neurons, recent work
in mammalian vestibular afferents has demonstrated a rich diversity in ion
channels that drive spiking regularity. Here, I review key ionic currents
studied in vitro and demonstrate how they may enable sensory encoding
strategies demonstrated in vivo.
