How Many Neurons Do We All Have?
Most of your neurons are sitting at like negative 70 millivolts. That's sort of like the range that we stick around. When an individual neuron is firing, that electrical signal that it sends is at the 70millivolts range. And then whenever it fires, it has to pass a threshold. The threshold is normally around negative 50 and then it can get up to positive 40. All of this is in relation to like the outside of the cell. So whatever is going on in the, the goo sort of surrounding the neuron. Yeah. Exactly. Together you have around 200 billion.
