| Research Abstract |
We investigated the response properties of neurons in the medial vestibular nucleus (MVN) to head rotations using whole-cell recordings in in vivo preparations of rats. Most MVN neurons tested increased the firing frequency in response to the head rotation to the recording side. Furthermore, the neurons showed an afterhyperpolarization with dual components and a repetitive firing pattern with relatively constant interspike intervals. This finding suggests that MVN neurons that show specific intrinsic properties respond to the head rotation to a specific direction.
