The research team developed the fourth element (aside from resistors, inductors, and capacitors), which is the core of neuromorphic engineering, the memrist. It imitates the process of learning and computing by the human brain and imitates the computer's computational structure in the form of an artificial neural network to mimic human learning ability. Memrist plays the same role as each core in which neurons in the brain process information. Neurons are connected by synapses, which play a role in processing information by exchanging spike signals (action potentials) between neurons.
