Is there an analogy of neurons demonstrated by electronics?

There are lots of different kinds. The generic name for them is artificial neural networks.

Multilayer perceptrons have a long history of implementation in analog electronics.

Memristors (resistors with hysteresis for their resistance value based on current) have been used recently to construct spiking neural networks, which of the basic ANNs are closest to the biological ones.

One of the building blocks that ANNs are made from, I guess. Like one of Pinky's memristors.

I wonder what Grey Walter Link2 made his turtle out of. Probably a bunch of transistors.

Perhaps a Solion resembles a single neuron.

2,815,488 (John Von Neumann, spoke of memory organs.

Neurons saturate if overstimulated.
