Neurons in the cerebral cortex, a region in the mammalian brain involved in complex motor functions, sensory perception and cognition, can have very different qualities and characteristics. These neurons are known to be formed ...
Our nervous system is composed of billions of neurons that speak to one another through their axons and dendrites. When the human brain develops, these structures branch out in a beautifully intricate yet poorly understood ...
