Question on Message travel through Nerves

[Zolar V]

In nerves the transmission of a message from the brain to wherever the message is going. Is it a electronic transmission?

if it is Electric what frequencie/voltage is it?

[Genecks]

An old theory states that transmission has been electrical.

I believe the modern theory states that transmission occurs via chemicals.

You also have electrochemical gradients that pass a signal.

 

Then again, there are physical properties, such as electronic properties, to neurotransmitters/ions that can make a person question both theories.

If is a somewhat easy read if you ignore some of the mathematics, but do understand polarization, depolarization, and propagation of a signal.

 

 

At the axon hillock of a typical neuron, the resting potential is around -70 millivolts (mV) and the threshold potential is around -55 mV.

You might want to look at some youtube videos about these topics, such as action potential and neurotransmission.
