Fig. 5From: Antibiotics-induced depletion of mice microbiota induces changes in host serotonin biosynthesis and intestinal motilityGut microbiota depletion by antibiotics regulates colonic contractility. Recordings were made of spontaneous phasic contractions of proximal colon. Representative recordings from antibiotics-treated mice (a) and control mice (b). Tension (c) and frequency (d) normalized to basal values in antibiotics-treated and control mice. Data are presented as mean ± SEM. ***P < 0.01Back to article page
