At Mind Matters News: Neuroscientist: Nervous systems alone do not cause consciousness

One-celled intelligence aside, it’s unclear how Antonio Damasio’s ladder of consciousness, built on self-balancing and death avoidance, gets us the human mind. Read More ›

At Mind Matters News, some fun: Would ET intelligences understand the 1974 Arecibo Message?

In early, easily-mocked sci fi, a little green man points his raygun at an unsuspecting passerby and barks “Take me to your leader.” Fast forward: If the little green man didn’t have the technology to figure out who the leader was before landing, he certainly wouldn’t have the technology to get here.

At Mind Matters News: What can mapping the whole brain tell us about ourselves ?

Researchers attempting to map the brain must contend with massive complexity at every level, as a report in Nature shows. The proposed whole brain map will shed light on many of these situations. If it doesn’t shed light on some of them, we are probably looking at a new frontier. Read More ›

“Junk DNA” is expressed differently in chimps and humans — and makes a difference in brain types

At GenEng and BioTech mag: "In a new study, stem cell scientists at the Lund University, Sweden, explore the role of non-coding regions of the genome—previously deemed to be functionless “junk” DNA—and find humans and chimpanzees use a part of their non-coding DNA in different ways. This they claim affects how and when the human brain develops." Read More ›

At Mind Matters News: GWT: A leading consciousness theory depends on information theory

If information flow in the brain is “largely unconstrained” by anatomical wiring, it’s easy to understand why we sense that we have “minds” apart from our brains. Read More ›

At Mind Matters News: Leading astronomer gets it all wrong about free will and destiny

In response to Harvard astronomer Avi Loeb denying free will and all that, neurosurgeon Michael Egnor points out, “Logic and reason aren’t laws of physics and therefore they transcend physical properties.” Read More ›

At Mind Matters News: Did minimal consciousness drive the Cambrian Explosion?

Eva Jablonka’s team makes the daring case, repurposing Hungarian chemist Tibor Gánti’s origin of life studies. Where their approach differs from many is that they do not try to identify a mechanism of consciousness. Read More ›

Eric Holloway: Move Over Turing and Lovelace – We Need a Terminator Test

The Turing test, and the Lovelace test, are attempts to determine if computers can show human-like intelligence. Holloway asks, what happens if researchers succeed in creating lifelike machines? in the sense of “wanting” things? "If we create an all-powerful artificial intelligence, we cannot assume it will be friendly. Thus, we need a Terminator test." Read More ›

World’s oldest art raises question: Is it art?

Researchers would not be asking if it is art if it were not so old (between 169,000 and 226,000). The underlying assumption seems to be that humans did not think imaginatively in those days. The evidence seems to contradict the evolutionary assumption. Read More ›

Maybe this is an argument for the rights of human embryos…

Researchers: The result revealed several key characteristics of the human embryonic development process. Firstly, mutation rates are higher in the first cell division, but then decrease to approximately one mutation per cell during later cell division. Secondly, early cells contributed unequally to the development of the embryo in all informative donors, for example, at the two-cell stage, one of the cells always left more progeny cells than the other. The ratio of this was different from person to person, implying that the process varies between individuals and is not fully deterministic. Read More ›

At Mind Matters News: A neuroscience theory that actually helps explain the brain

Epstein's theory is that that the brain is a type of transducer, that is, a device or an organ that converts one signal to another signal, commonly from one medium to another. A microphone, for example, is a transducer that converts sound waves to electrical current. Your eye is a transducer that converts light to vision. So the brain converts thoughts to material effects.
