    Researchers identified cold-sensitive afferent nerve fibers in the splanchnic nerves of cats, originating from the stomach and duodenum. Thermal stimuli did not affect vagus nerve afferents, suggesting distinct sensory pathways.

    Area of Science:

    • Neuroscience
    • Gastroenterology
    • Physiology

    Background:

    • The visceral sensory system plays a crucial role in regulating gastrointestinal functions and relaying internal bodily states.
    • Understanding the specific afferent pathways involved in sensing temperature and mechanical stimuli within the abdomen is essential for comprehending visceral perception and reflexes.

    Purpose of the Study:

    • To investigate the presence and characteristics of thermal and mechanical afferent nerve fibers in the splanchnic and vagus nerves of cats.
    • To determine the origin and sensitivity of these afferent pathways within the abdominal viscera.

    Main Methods:

    • Electrophysiological recordings were performed on afferent nerve fibers in splanchnic and vagus nerve preparations in anesthetized cats.
    • Nerve fibers originating from the stomach, duodenum, intestine, mesentery, and blood vessels were stimulated and their responses to thermal and mechanical stimuli were analyzed.

    Main Results:

    • Cold-sensitive afferent fibers were identified within the splanchnic nerves innervating the stomach and duodenum.
    • Numerous mechanosensitive afferent fibers were found originating from the stomach, intestine, mesentery, and surrounding blood vessels.
    • No thermal afferent fibers were detected in the vagus nerve, and cardiovascular and respiratory afferents showed no sensitivity to thermal stimuli.

    Conclusions:

    • The splanchnic nerves contain specific cold-sensitive afferent pathways originating from the upper gastrointestinal tract.
    • The vagus nerve does not appear to transmit thermal information from these abdominal regions, indicating a functional segregation of sensory pathways.
    • Visceral mechanosensation is mediated by a diverse population of afferent fibers originating from various abdominal structures.
