Human brain cells in a dish learn to play Pong

Live biological neurons show more about how a brain works than AI ever will

A Melbourne-led team has for the first time shown that 800,000 brain cells living in a dish can perform goal-directed tasks – in this case the simple tennis-like computer game, Pong. The results of the study are published today in the journal Neuron.

Now they are going to find out what happens when their DishBrain is affected by medicines and alcohol.

“We have shown we can interact with living biological neurons in such a way that compels them to modify their activity, leading to something that resembles intelligence,” says lead author Dr Brett Kagan, who is Chief Scientific Officer of biotech start-up Cortical Labs, dedicated to building a new generation of biological computer chips. His co-authors are affiliated with Monash University, RMIT University, University College London and the Canadian Institute for Advanced Research.

Brain temperature can now be measured using light

Nanotech technique could revolutionise neurological treatments.

Light could replace invasive techniques to measure brain temperature– eliminating the need to place a thermometer in the brain when treating a range of neurological disorders.

Researchers from Victoria’ Swinburne University have teamed up with Universidad Autónoma de Madrid in Spain and Stanford University in the US to develop a technique for measuring sub-degree brain temperature changes using near-infrared light.

Science in Charlie Teo's Australia Day address

In his Australia Day address, noted brain surgeon Charlie Teo said he was ashamed to admit to an American friend, who had received a US$50 million grant in the US to study brain cancer, that he works with just AU$150,000 over three years from the Australian government.

Teo says we need another AIS – one for sport, one for science.

How does our intelligence change through life

Nature paper reveals the genetic influence on our IQ as we age

Embargo 6 am AEST, Thursday 19 January 2012

Issued for the Queensland Brain Institute, University of Queensland.

Researchers from Brisbane, Edinburgh and Aberdeen have revisited about 2,000 people who had intelligence tests in 1932 or1947, and shown that genetic factors may account for about a quarter of the changes in intelligence over their lives.
