Artificial neurons are much like human neurons, but there are some functional differences. The MicroNano Research Facility at the Melbourne Institute of Technology have designed a multi-state memory that mimics a human neuron's ability to concurrently process and store multiple strands of data. The key to the multi-state memories is a memristive effect that stores a scale of values. Such memories may also help us understand why our brains seem more complex than the artificial networks we construct.
