The substance that is produced and released by neurons in the brain is a hormone called dopamine. It acts as a neurotransmitter that sends signals between nerve cells.
Theres billions of neurons in the brain
Afferent neurons (also called sensory neurons) carry signals to the central nervous system and the brain. Efferent neurons (also called motor neurons) carry signals from the brain.
It is said that central nervous system and enteric nervous system contain 1 billion neurons each.
"100 billion", that's how many neurons there are totally in the human brain, I am interested if I "cut" a part of the human brain that was a cubic inch how many neurons would be in there?
Neurons
Neurons are brain cells
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
The Substance produced that kills pain is called Endorphins
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.
Glucose is the main source of energy of the brain. It is converted to ATP inside the brain. However, the brain cells (neurons) themselves use some glucose. The other glucose is first metabolized and converted to "Lactate" by cells inside the brain called "Astrocytes". The lactate produced will then enter the neurons and then is converted to ATP.
Motor Neurons
MOTOR neurons
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.
Receptor neurons in the nostrils first detect an odor by coming into contact with and reacting to gas molecules of the substance. Then the receptor neurons send information about the odor along the olfactory nerve to the brain.
The brain is composed of two types of cells, neurons and glial cells.
