Why don't neurons in the brain fire all the time?

There are several reasons why neurons don't fire all the time: 1. Neurons receive a balance of both excitatory and inhibitory input, as explained by Colin Gerber. read more

5. The brain can't handle neurons firing all the time. Neurons fire around 10x per second and already the brain is consuming 20% of the body's energy at 2% of the body's weight. If neurons fired 20x (or 100x!) per second, that would be 30% (or 70%) of the body's total energy. read more

The electrical charge is conducted by a nerve chain to the neurons in your brain. (There are way more than 100 trillion of those in your brain.) There is a gap between that nerve ending and the next nerve. Several neurons can reach a common point and the combined charges can jump together along the way or in the brain. read more
