20 billion in a normal adult. -just bercyl
I am a certified neurologist and have worked for thirty years at Stanford University. There is approximately thirty million neurons in the average human brain.
did
About 1,000,000,000. Or one billion.100 billion neuron cells re in the brainThere are approximately 100 billion neurons in the human brain.
There is about 160,000,000,000 cells in human brain. Half of the number are neurons, which are rensponsible for all the "thinking" functions. The other half are "glial cells", which help neurons with their activity.
There are 2 different kinds of neurons within the body. The neurons that carry messages from senses to the brain are called Sensory Neurons while the neurons that cause the brain to make the body react are called Motor, or efferent, neurons.
100 billion neurons
Neurons are like they brains messengers. The brain figures out what needs to be done and the neurons tell they body to do it.

No. Neurons come and go throughout your life. The average (adult) human brain gains about 9000 neurons a day.
The number is very high, but not infinite. There are around 5*10^12 connections in the average brain. (100 million neurons each electricly and chemicly connected to 50 000 other neurons)
No, a quadrillion transistors is not approximately the same as the number of neurons in the human brain, because the neurons can make multiple connections to other neurons. Also, it is more than just a "number of bits" in the brain - it is chemistry, meaning that it is more analog than digital - and it is (in some schools of thought) spiritual and/or quantum or sub atomic.
Neurons are brain cells

The mind is composed of neurons (nerve cells) in the brain. There are billions of neurons in a cubic inch of brain matter. These neurons can form connections with any number of other neurons in trillions of different ways. That is complex, so the mind is complex.
Neurons are nerve cells. Neurons in the brain are involved in thinking and perceiving and consciousness and control of the body, and neurons elsewhere in the body communicate with the brain.

most of the neurons in the brain and spinal cord are
