Toward brain-like computing: New memristor better mimics synapses

A new electronic device developed by Prof. Wei Lu and collaborators can directly model the behaviors of a synapse, which is a connection between two neurons. For the first time, the way that neurons share or compete for resources can be explored in hardware without the need for complicated circuits. "Neuroscientists have argued that competition and cooperation behaviors among synapses are very important. Our new memristive devices allow us to implement a faithful model of these behaviors in a solid-state system," said Lu. [Full Story]
