Outline of Final Research Achievements |
The caudal part of trigeminal nucleus (Sp5C) is involved in nociceptive information processing from the head and orofacial regions. Sp5C neurons project to a number of regions within the thalamus, periaqueductal gray and hypothalamus. These projections are thought to be involved in cardiovascular and visceral modifications which are associated with noxious stimulation. In the present study, we investigated axonal and dendritic arborizations of single Sp5C neurons in rats with single neuron labeling method. The results suggest that a few Sp5C neurons projects to thalamus directly, but most Sp5C neurons innervates within Sp5 or near regions.
