The eventual
human brain simulation will take place at the Juelich Supercomputing Center in northern Germany, Curioni said.
His competitor, the IBM researcher Dharmendra Modha, announced a simulation of a cat brain, after having claimed a
mouse brain simulation in 2007.
I thought that... journalists would be able to recognize that what IBM reported is a scam - nowhere near a cat -
scale brain simulation, but somehow they are totally deceived by these incredible statements.
These are all important caveats, but models of neuron types and connectome change still fit into the overall framework of connectome -
based brain simulation.
Henry Markram has become famous as the creator of the world's most
expensive brain simulation, but neuroscientists know him best for his pioneering experiments on synapses.
The researchers have used these chips to create one of the most
comprehensive brain simulations to date — a digital reconstruction of some 31,000 neurons, and 37 million synaptic connections, in a sand grain - sized chunk of the rat brain.
«The challenge
of brain simulation is that the nerve cells enter into a temporary relationship with other neurons depending on the task at hand,» says Prof. Dr. Markus Diesmann, director of Juelich's institute Computational and Systems Neuroscience (INM - 6).
1 billion Number of neurons, linked by 10 trillion synapses, in
a brain simulation developed by IBM and Lawrence Berkeley National Lab, running on the Dawn supercomputer.
In a follow - up experiment involving 156 participants, the researchers found that the positive effect of
the brain simulation is only applicable when their dishonest behavior benefited the participants themselves rather than another person.
In terms of
brain simulation, the challenges are even bigger: The world's fourth most powerful supercomputer took 40 minutes to model one second of brain activity in a simulated network containing 1.73 billion neurons and over a trillion synapses, yet this represents just one per cent of neuronal networks in the human brain.
