A joint team of European scientists digitally recreated essential area of rat brain, which may soon help other researchers encode the entire human brain into a computer model. The goal of the project is to define all the different types of neurons found in the brain, measure their electricity-firing properties, and create a roadmap of the circuits that connect the neurons to one another. They recently theorized that the sudden shift in the level of calcium ions is able to alter the brain’s behavioral response. The 747 the researchers have built, she said, is barely taking around the runway. This miniscule digital recreation of a rat’s brain is the scientific community’s most detailed brain models yet. That led to a set of fundamental rules describing how neurons connect to synapses and form microcircuits. All of that data was then run through a supercomputer: “It was only with this kind of infrastructure that we could solve the billions of equations needed”, said software lead Felix Schurmann.

The hottest investigation is earned from the Blue Brain Project, which generally strives to effectively digitalize the mouse grey matter and ultimately contain only the breakthrough in to share mind into a working laptop or computer.
Once they created the model, scientists moved on to simulating it. The results were exciting: they seemed to correlate with rat brain experiments in the real world, suggesting that the researchers were on the right track. Once that is done, they will be able to work towards getting a full, accurate and high-resolution picture of the brain.
However, he mentioned that their achievement does not mean scientists are anywhere near the possibility of reconstructing a complete rat brain, let alone a human brain of 85 billion neurons or even more. To develop this uniquely complex and incredible simulation of the characteristically electrical behavior of virtual brain tissue, the researchers used supercomputers, of course, guiding their work with key insights into how the neocortex function. They found that the reconstruction did indeed express the triplets and also made a new discovery: the triplets only occur when the circuit is in a very special state of activity. These findings wouldn’t have been reached by looking at the features of individual neurons.
“The reconstruction required an enormous number of experiments”, Henry Markram, of the Ecole Polytechnique Federale de Lausanne where the research has been conducted, said in a statement. In fact, the current version explicitly leaves out many important aspects of the brain, such as glia, blood vessels, gap-junctions, plasticity, and neuromodulation.

Critics additionally mentioned that the Blue Brain project (BBP) engulfed a few huge cash and produced little to no outcomes.
