To Control Ionization. 1  Ionization Voltage Typically, 70eV electrons from the filament are used for EI. 2  Emission Current The number of ions produced in unit time is proportional to the current of emitted electrons, i.e., emission current. 3  Ion Source Temperature The ion source is usually used at about 200 oC.
IN is also observed in DA neurons, and it activates at the same thresholds as IL, but it requires prior hyperpolarization of the membrane (to -90 mV) and is w-conotoxin-sensitive. Both IL and IN, but not IT, are reduced by stimulation of the DA autoreceptor ().
