Patch Clamp Recordings from Embryonic Zebrafish Mauthner Cells
Mauthner cells (M-cells) are large reticulospinal neurons located in the hindbrain of teleost fish. They are key neurons involved in a characteristic behavior known as the C-start or escape response that occurs when the organism perceives a threat. The M-cell has been extensively studied in adult goldfish where it has been shown to receive a wide range of excitatory, inhibitory and neuromodulat...
متن کاملPatch Clamp Recordings in Inner Ear Hair Cells Isolated from Zebrafish
Patch clamp analyses of the voltage-gated channels in sensory hair cells isolated from a variety of species have been described previously(1-4) but this video represents the first application of those techniques to hair cells from zebrafish. Here we demonstrate a method to isolate healthy, intact hair cells from all of the inner ear end-organs: saccule, lagena, utricle and semicircular canals. ...
متن کاملPatch-clamp recordings from lateral line neuromast hair cells of the living zebrafish.
Zebrafish are popular models for biological discovery. For investigators of the auditory and vestibular periphery, manipulations of hair cell and synaptic mechanisms have relied on inferences from extracellular recordings of physiological activity. We now provide data showing that hair cells and supporting cells of the lateral line can be directly patch-clamped, providing the first recordings o...
متن کاملWhole-Cell Patch-Clamp Recordings
The patch-clamp recording technique, which measures ionic currents under voltage clamp, was designed to study small patches of membranes in which near perfect control of the transmembrane voltage can be achieved readily. The recent application of patch-clamp methodology to the analysis of whole-cell current actually defies many of the original design requirements. Nevertheless, whole-cell recor...
متن کاملPaired Patch Clamp Recordings from Motor-neuron and Target Skeletal Muscle in Zebrafish
Larval zebrafish represent the first vertebrate model system to allow simultaneous patch clamp recording from a spinal motor-neuron and target muscle. This is a direct consequence of the accessibility to both cell types and ability to visually distinguish the single segmental CaP motor-neuron on the basis of morphology and location. This video demonstrates the microscopic methods used to identi...
