Question

The axon has a diameter of 30 um, a length of 5 cm. I calculated the capacitance to be 12.525. The fractional change in the concentration of Na⁺ ions inside the axon during one action potential is 2.7 x 10^-5 .

The energy used to create one action potential along this axon is pJ. (Hint: The energy to transmit one pulse is equivalent to the energy stored by charging the axon capacitance.) The minimum power that would be required for 104 neurons transmitting 100 pulses per second would be uW.
