Japanese Researchers Develop Artificial Synapse
Japanese researchers developed a tiny device that has a gap bridged by a copper filament under a voltage pulse stimulation. This results in a change in conductance which is time-dependant — a change in strength that’s nearly identical to the one found in biological synaptic systems. The inorganic synapses could thus be controlled by changes in interval, amplitude, and width of an input voltage pulse stimulation.
Why this is exciting is that the device is essentially mimicking the major features of human cognition, what the researchers refer to as the “emulation of synaptic plasticity”, including what goes on in short-term and long-term memory. Not only that, it responds to the presence of air and temperature changes, which indicates that it has the potential to perceive the environment much like the human brain.
The researchers are hoping that their newfound insight could help in the development of artificial neural networks, but it’s clear that their system, which operates at a microscopic level, could also be used to treat the human brain. The day may be coming when failing synaptic systems could be patched with a device similar to this one, in which biological function is offloaded to a synthetic one.
