Before you understand this, you must know what exactly is action potential. Action potential is part of process which occurs during a firing of a neuron. During action potential, neural membrane allows in the positively charged ions in and negatively charged ones out. read more
The resting potential of the neuron refers to the difference between the voltage inside and outside the neuron. The resting potential of the average neuron is around -70 millivolts, indicating that the inside of the cell is 70 millivolts less than the outside of the cell. read more
The brain is a multi-layered ecosystem of hierarchically organized neurons, circuits, networks, and brain areas. The neurons emit pulses called "spikes" that last about 1 millisecond. Each neuron fires (emits a spike) on the order of 10 times per second. read more
To answer that question, we need to look at just three variables*: How many neurons we have. How fast neurons fire. How many cells each neuron connects to. Neurons are nerve cells that process and transmit electrochemical signals. Like a little lightning bolt transmitter/receiver/processor. read more
