水平眼球運動に関与するネコ脳幹ニューローン群の形態学的解析

抄録

The morphology of horizontal eye movement-related brainstem neurons (Second-order Type I neuron, Abducens motoneuron, Abducens internuclear neuron, Reticular burst neuron, Omnipause neuron) was investigated by intracellular staining with horseradish peroxidase (HRP). Axons and cell bodies of these neurons penetrated in and around the abducens nucleus were identified by their characteristic firing patterns. After injection of HRP each neuron was reconstructed in three dimension using a microscope equipped with a camera lucida drawing attachment. The morphological findings of this study almost correspond with previous electrophysiological studies.
