From Kurzweil on our brain

Do we have free will?

Neuroscientists run the ultimate experiment to find out: a "duel" between human and brain-to-computer interface (BCI)
It’s a question that’s been debated by philosophers for centuries. Now neuroscientists from Charité –Universitätsmedizin Berlin have run an experiment to find out, using a “duel” game between human and brain-computer interface (BCI). As KurzweilAI reported last year: In the early 1980s, University of California, San Francisco neuroscientist Benjamin Libet conducted an experiment to assess the nature of free … more…
How brain architecture relates to consciousness and abstract thought
December 29, 2015

Generated by human-blind automated procedures, this diagram depicts an oversimplified graphical model of the information representation flow from sensory inputs (bottom) to abstract representations (top) in human cortex. Bottom layer of the pyramid included a sample representative description of the 20th percentile of behavioral elements closest to sensory inputs, the next layer up includes a sample description of behavioral elements from the 20–40th percentile…with the top layer containing a sample description of the behavioral elements distributed deepest in the cortical network, at the structural pinnacle of cognition.

Could lead to better ways to identify and treat brain diseases and to new deep-learning AI systems
Ever wonder how your brain creates your thoughts, based on everything that’s happening around you (and within you), and where these thoughts are actually located in the brain? UMass Amherst computational neuroscientist Hava Siegelmann has, and she created a geometry-based method for doing just that. Her team did a massive data analysis of 20 years … more…
Can human-machine superintelligence solve the world’s most dire problems?
January 5, 2016

New human-computation technologies: In creating problem-solving ecosystems, researchers are beginning to explore how to combine the cognitive processing of many human contributors with machine-based computing to build faithful models of the complex, interdependent systems that underlie the world’s most challenging problems. (credit: Pietro Michelucci and Janis L. Dickinson/Science)Human Computation Institute | Dr. Pietro Michelucci “Human computation” — combining human and computer intelligence in crowd-powered systems — might be what we need to solve the “wicked” problems of the world, such as climate change and geopolitical conflict, say researchers from the Human Computation Institute (HCI) and Cornell University. In an article published in the journal Science, the authors … more…

Cognitive-stimulation experiment suggests new tools for healthy brain aging
January 8, 2016

DMN connections
May also have a "preventive and therapeutic role in association with early AD-type neurodegeneration"
Neuroscientists in Italy and the U.K. have developed cognitive-stimulation exercises and tested them in a month-long experiment with healthy aging adults. The exercises were based on studies of the brain’s resting state, known as the “default mode network”* (DMN). In a paper published in Brain Research Bulletin, the researchers explain that in aging (and at a … more…
