The evacuative motor responses of the anal canal and recto-anal reflexes during defecation were studied in an isolated rat recto-anal model preparation using (i) partitioned organ bath, (ii) electrical stimulation, (iii) balloon distension and (iv) morphological techniques. Electrical field stimulation

The parafacial respiratory group (pFRG) in the rostral ventrolateral medulla of the newborn rat is predominantly composed of pre-inspiratory (Pre-I) neurons and is involved in respiratory rhythm generation. The subgroup located close to the ventral surface (at least partially overlapping

Acute cutaneous neurogenic inflammation initiated by activation of transient receptor potential vanilloid-1 (TRPV1) receptors following intradermal injection of capsaicin is mediated mainly by dorsal root reflexes (DRRs). Inflammatory neuropeptides are suggested to be released from primary afferent nociceptors participating in

Five undeca- and six C-terminal heptapeptide substance P (SP) analogues were tested for their capacity to block the contractile effect of SP on the guinea-pig isolated taenia coli. They had one feature in common, namely substitutions in positions 7 and

In the present study, we tested the hypothesis that substance P (SP) is an excitatory peptide to the rat carotid body and plays an important role in chemosensory excitation by hypoxia. Chemosensory discharge was recorded from the cut carotid sinus
