Neurons

Definition

Neurons are specialized cells that transmit information throughout the nervous system, functioning as the basic building blocks of the brain and nervous system. They are responsible for processing and transmitting signals in the form of electrical impulses and chemical signals, allowing for communication between different parts of the body. In the context of neuromorphic computing architectures, neurons serve as models that mimic biological processes to perform computations and simulate cognitive functions.
