AbstractThe response properties of extracellularly recorded Y group neurons on the lesioned side were examined in decerebrate cats after acute hemilabyrinthectomy, with the use of constant velocity off-vertical axis rotations (OVAR) to stimulate the remaining intact otolith receptors. During rotation in the clockwise or counterclockwise direction, Y group neurons displayed a spectrum of position-dependent bidirectional response sensitivities, ranging from one- to two-dimensional. Some two-dimensional neurons even exhibited unidirectional responses with change in OVAR velocity. These findings indicate that Y group neurons have the capacity to code spatiotemporal signals arising from the contralateral otolith. The best response orientations of one-dimensional and two-dimensional neurons were found predominantly along the anteroposterior direction, thus providing a spatial framework for the otolithic reflexes. © 2003 Lippincott Williams & Wilkins.
