Jan 16, 2024 · Neurons, also known as nerve cells, are essentially the cells that make up the brain and the nervous system. Neurons do not touch each other, but where one neuron comes close to another neuron, a synapse is formed between the two. According to new research, the human brain contains around 86 billion neurons (Herculano-Houzel, 2009).
