Calbindin D-28k-containing neurons receiving visceral and somatic nociceptive information in interstitial nucleus of the spinal trigeminal tract project to the parabrachial nuclei in the rat;

AIM: To investigate the projection of the calbindin D 28k (CB) containing neurons that receive orofacial deep structures (masseter muscles) nociceptive information from the interstitial nucleus of the spinal trigeminal tract (INⅤ) directly to nucleus of the solitary tract (NTS).

In order to investigate whether neurons containing CB in the interstitial nucleus of the spinal trigeminal tract (INV) receive the orofacial somatic nociceptive information and transmit it to nucleus of the solitary tract(NTS), the triple-labeled method of FG retrograde tracing combined with FOS and CB protein immunofluorescence histochemistry was used.

Synaptic connections of the slow adapting lingual afferent terminals in the principal trigeminal nucleus and nucleus of spinal trigeminal tract in cats;

Several anatomical studies using either degeneration or tract-tracing methods have demonstrated the efferent and afferent connections of the interpolaris subnucleus of the spinal trigeminal nucleus (Vi).

Objective To explore futher the possible action of substance P (SP) fibers (SP) to spinal trigeminal caudal subnucleus (Vc) on the sensory neurotransmission.

The study of calcitonin gene related peptide in trigeminal subnucleus caudalis during experimental tooth movement;

Objective: To investigate Fos expression in the neurons of spinal cord and the trigeminal subnucleus caudalis (Vc) projecting to the subnucleus reticularis dorsalis (SRD) under peripheral noxious stimulation in the rat.

To investigate synaptic relations between the laminaⅡneurons and projecting neurons in the trigeminal subnucleus caudalis (Vc), we employ retrograde tracing and electronmicroscopy methods to examine the CB-LI and PV-LI positive synaptic connections with projecting neurons from Vc.
