We have always accepted that some people seem to do better on cognitive tasks than others, and now there are scans to 'prove' it.  However, given the neuroplastic nature of the connections, and the strong role that "fire together, wire together" effects alter the connection map - will getting a low or high score as a child become a self fulfilling prophecy?

Roger Penrose: The Human Brain is More Complex than a Galaxy

Roger Penrose: The Human Brain is More Complex than a Galaxy | Chasing the Future | Scoop.it

According to physicist, Roger Penrose, What’s in our head is orders of magnitude more complex than anything one sees in the Universe: "If you look at the entire physical cosmos," says Penrose, "our brains are a tiny, tiny part of it. But they're the most perfectly organized part. Compared to the complexity of a brain, a galaxy is just an inert lump." 

 

Each cubic millimeter of tissue in the neocortex, reports Michael Chorost in World Wide Mind, contains between 860 million and 1.3 billion synapses. Estimates of the total number of synapses in the neocortex range from 164 trillion to 200 trillion. The total number of synapses in the brain as a whole is much higher than that. The neocorex has the same number of neurons as a galaxy has stars: 100 billion.  "All stars can do is pull on each other with gravity," writes Chorost, and, if they are very close, exchange heat."

 

One researcher estimates that with current technology it would take 10,000 automated microscopes thirty years to map the connections between every neuron in a human brain, and 100 million terabytes of disk space to store the data.

 

Galaxies are ancient, but self-aware, language-using, tool-making brains are very new in the evolutionary timeline, some 200,000-years old. Most of the neurons in the neocortex have between 1,000 and 10,000 synaptic connections with other neurons. Elsewhere in the brain, in the cerebellum, one type of neuron has 150,000 to 200,000 synaptic connections with other neurons. Even the lowest of these numbers seems hard to believe. One tiny neuron can connect to 200,000 neurons.

 

"The universe could so easily have remained lifeless and simple -just physics and chemistry, just the scattered dust of the cosmic explosion that gave birth to time and space," says Richard Dawkins, the famed Oxford evolutionary biologist reflecting on the sheer wonder of the emergence of life on Earth and the evolutionary process in his classic The Ancestor's Tale.

 

"The fact that it did not -the fact that life evolved out of literally nothing, some 10 billion years after the universe evolved literally out of nothing -is a fact so staggering that I would be mad to attempt words to do it justice. And even that is not the end of the matter. Not only did evolution happen: it eventually led to beings capable of comprehending the process by which they comprehend it."

Human Brain Project: Henry Markram plans to spend €1bn building a perfect model of the human brain

Human Brain Project: Henry Markram plans to spend €1bn building a perfect model of the human brain | Chasing the Future | Scoop.it

Henry Markram tells how his son's autism fired his ambition to unlock the secrets of consciousness by using 'big data' to trace the electronic signals that zing between neurons

With a ten year time frame its arrival might be a little late for some in the research market but any outputs may change the way we view human behaviour and thus how we conduct market research.

Brain Surgeons Find The Neurological Basis of Human Speech

Brain Surgeons Find The Neurological Basis of Human Speech | Chasing the Future | Scoop.it

A team of scientists at UC San Francisco has uncovered the neurological basis of speech motor control, the complex coordinated activity of tiny brain regions that controls our lips, jaw, tongue and larynx as we talk.
Published recently in the journal Nature, the work has potential implications for developing computer-brain interfaces for artificial speech communication and for the treatment of speech disorders. It also sheds light on an ability that is unique to humans among living creatures but poorly understood.

Scientists Send Messages Directly From One Brain To Another

Scientists Send Messages Directly From One Brain To Another | Chasing the Future | Scoop.it

But the cumbersome experimental setup won’t replace Facebook's Messenger app anytime soon. So a team of neuroscientists sent a message from the brain of one person in India, to the brains of three people in France, using brainwave-reading equipment and the Internet. Yes, really.

Biology Confronts Data Complexity

Biology Confronts Data Complexity | Chasing the Future | Scoop.it

New technologies have launched the life sciences into the age of big data. Biologists must now make sense of their informational windfall.

Tratar la vida como un cumulo de datos... qué se yo... estamos yendo a eso.

tatiyana fuentes's curator insight, October 24, 2013 8:49 AM

It was difficult to find sequence the human genome, but now it’s comparatively simple to compare genomes of the microorganisms living in our bodies, the ocean, the soil, and everywhere because of the new technologies. Life scientists are embarking on countless other big data projects, including efforts to analyze the genomes of many cancers, to map the human brain, and to develop better biofuels and other crops. Compared to fields like physics, astronomy and computer science that have been dealing with the challenges of massive datasets for decades, the big data revolution in biology has also been quick, leaving little time to adapt. Biologists must overcome a number of hurdles, from storing and moving data to integrating and analyzing it, which will require a substantial cultural shift.

Brown University creates first wireless, implanted brain-computer interface

Brown University creates first wireless, implanted brain-computer interface | Chasing the Future | Scoop.it

Brown’s wireless BCI, fashioned out of hermetically sealed titanium, looks a lot like a pacemaker. Inside there’s a li-ion battery, an inductive (wireless) charging loop, a chip that digitizes the signals from your brain, and an antenna for transmitting those neural spikes to a nearby computer. The BCI is connected to a small chip with 100 electrodes protruding from it, which, in this study, was embedded in the somatosensory cortex or motor cortex. These 100 electrodes produce a lot of data, which the BCI transmits at 24Mbps over the 3.2 and 3.8GHz bands to a receiver that is one meter away. The BCI’s battery takes two hours to charge via wireless inductive charging, and then has enough juice to last for six hours of use.

Project Seeks to Build Map of Human Brain

Project Seeks to Build Map of Human Brain | Chasing the Future | Scoop.it

The Obama administration is planning a decade-long scientific effort to examine the workings of the human brain and build a comprehensive map of its activity, seeking to do for the brain what the Human Genome Project did for genetics.
The project, which the administration has been looking to unveil as early as March, will include federal agencies, private foundations and teams of neuroscientists and nanoscientists in a concerted effort to advance the knowledge of the brain’s billions of neurons and gain greater insights into perception, actions and, ultimately, consciousness.
