Dr. Maria Bertuzzi & Dr. Konstantinos Ampatzis from Karolinska Institutet used a Loligo^® 5 L swim tunnel respirometer to test the critical swimming speed (U_crit) in multiple adult zebrafish. The researchers investigated the functional flexibility of motoneurons and how the neurons execute locomotion at different speeds. Specifically, Bertuzzi & Ampatzis found that cholinergic interneurons are present in the zebrafish spinal cord and differentially control the excitability of distinct classes of motoneurons (slow, intermediate and fast) in a muscarinic dependent manner. Their unexpected findings are published in Nature’s Scientific Reports. Scientific Reports.
