Neuron | Vibepedia

Neurons, also known as nerve cells, are excitable cells that transmit and process information through electrical and chemical signals, playing a crucial role in the functioning of the nervous system. They are the main components of nervous tissue in animals, excluding sponges and placozoans. The evolution of neurons dates back to around 700-800 million years ago, during the Tonian period, with predecessors such as peptidergic secretory cells. Researchers like Santiago Ramón y Cajal and Camillo Golgi have significantly contributed to our understanding of neurons, using techniques like Golgi staining to study their structure and function.
