Insect Nervous System Copied To Boost Computing Power
by Charles Q. Choi
Brains are the most powerful computers known. Now microchips built to mimic insects’ nervous systems have been shown to successfully tackle technical computing problems like object recognition and data mining, researchers say.
Attempts to recreate how the brain works are nothing new. Computing principles underlying how the organ operates have inspired computer programs known as neural networks, which have been used for decades to analyze data. The artificial neurons that make up these programs imitate the brain’s neurons, with each one capable of sending, receiving and processing information.
However, real biological neural networks rely on electrical impulses known as spikes. Simulating networks of spiking neurons with software is computationally intensive, setting limits on how long these simulations can run and how large they can get.
