Synaptic potentials can be recorded by:
Correct Answer: Microelectrode
Description: 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
