The average human brain contains about 86 billion nerve cells, called neurons. These are the building blocks of your brain. Neurons communicate with each other by sending chemical and electrical signals. ... Impulses rush along tiny fibres, like electrical wires, from one neuron to the next.
Neurons communicate with each other by sending chemical and electrical signals. Each neuron is connected with other neurons across tiny junctions called “synapses.” Impulses rush along tiny fibers, like electrical wires, from one neuron to the next. Electrical impulses travel through neurons.
