<prompt> Synaptic potentials can be recorded by:Patch clamp techniqueVoltage clamp techniqueMicroelectrodeEEG  <response>: C i.e. Microelectrode Nerve cells have a low threshold for excitation. The stimulus may be electrical, chemical or mechanical. Two types of physio chemical disturbances are produced: I Local, non propagated potential - synaptic or electrotonic potential II Propogated disturbance - action potential nerve impulse Measurement of electrical activity in nerve The electric events in neurons are rapid being measured in millisecond ms and the potential changes are small, measured in millivolts my The electrical activity can be measured by I MicroelectrodeQ with tip diameter of less than 1 micron II Electronic amplifier III Cathode ray oscilloscope
