<b>Neuron-like cells in the chick spinal accessory lobe express neuronal-type voltage-gated sodium </b><b>channels </b>

Abstract: Ten pairs of protrusions, called accessory lobes (ALs), exist at the lateral sides of the avian lumbosacral spinal cord. Histological evidence indicates that neuron-like cells gather in the ALs, and behavioral evidence suggests that the ALs act as a sensory organ of equilibrium during bipedal walking. Recently, using an electrophysiological method, we reported that cells showing Na currents and action potentials exist among cells that were dissociated from the ALs. However, it was unclear which isoforms of the… Show more

“…Rosenberg and Necker (2002) found dendritic projections of the accessory lobe neurons that extend into fluidfilled lacunae, analogous to the stereocilia of inner ear hair cells. Cells in the accessory lobes have neuronal-type voltage-gated sodium channels (Yamanaka et al, 2008, Matsushita et al, 2018, indicating the presence of neurons that can generate action potentials and are thus capable of acting as Necker suggests. In addition, there is evidence that implicates GABA (Yamanaka et al, 2012), glutamate (Yamanaka et al, 2013), and acetylcholine (Takahashi et al, 2015) in accessory lobe neuron function.…”

“…In addition, there is evidence that implicates GABA (Yamanaka et al, 2012), glutamate (Yamanaka et al, 2013), and acetylcholine (Takahashi et al, 2015) in accessory lobe neuron function. However, no specific transduction mechanism has been identified (as noted by Matsushita et al, 2018). Necker (1997) traced the accessory lobe neuron axons to the contralateral lamina VIII of the spinal cord, which is implicated in mammals in leftright limb coordination (Harrison et al, 1986).…”
