Monitoring Electrical Signals from the Afferent Neurons in an Immobilized Zebrafish Larva

Source: Lunsford, E. T., et al. Activity of Posterior Lateral Line Afferent Neurons during Swimming in Zebrafish. J. Vis. Exp. (2021). This video demonstrates the recording of electrical signals from the afferent neurons in a paralyzed zebrafish larva by positioning a micropipette near the lateral line ganglion and forming a loose seal for signal capture. The extracellular solution maintains neuronal viability during this process.
