In embryonic vestibular nuclei neurons, spontaneous synaptic events do not routinely reach the threshold for firing action potentials due to their small amplitude (Peusner and Giaume, 1994). These signals are used for a variety of functions, including the control of reflex and voluntary movements and the construction of a sense of self-motion. Whether a stimulus-specific and topographic organization of the thalamic nuclei exists is still unknown.
