Zolar V Posted March 10, 2010 Share Posted March 10, 2010 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? Link to comment Share on other sites More sharing options...
Genecks Posted March 25, 2010 Share Posted March 25, 2010 (edited) 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. You might want to read this: http://en.wikipedia.org/wiki/Action_potential 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. source: http://en.wikipedia.org/wiki/Action_potential#Overview_for_a_typical_neuron You might want to look at some youtube videos about these topics, such as action potential and neurotransmission.
