Neuron
A neuron is a specialized cell in the nervous system that processes and transmits information through electrical and chemical signals, acting as the building blocks of the brain and spinal cord. In modern contexts, neurons are crucial for understanding everything from human cognition to artificial intelligence, where they inspire neural networks that mimic biological processes for machine learning.

The human brain contains about 86 billion neurons, which is roughly the same number as the stars in the Milky Way, enabling astonishing feats like memory formation and creativity. Remarkably, studies show that certain neurons, such as those in the hippocampus, can regenerate throughout life, a discovery that has revolutionized our understanding of brain repair and aging since the 1990s.
