Electrophysiology intracellular muscle recording

Figure 2. Schematic diagram the electrophysiological assay used to test for biological activity of spider venom components. Lx>ngitudinal ventrolateral muscles of Musca domestica were impaled with an intracellular microelectrode, which recorded excitatory junctional potentials (EJP) in response to nerve stimulation or ionophoretic junctional potentials (IP) in response to glutamate application by ionophoresis.
