In recent years the two largest brain research projects have been a big US project launched in 2013 called the BRAIN Initiative, and a big European Union project launched in 2013 called the Human Brain Project. The BRAIN Initiative has received billions in funding, but has failed to fulfill the boasts it made about what it would do by the year 2025.
More than seven years ago, the leaders of the BRAIN Initiative produced a document filled with hubris, one boasting about the grand and glorious things the project would achieve by the year 2025. The document was called Brain 2025: A Scientific Vision, and was offered at one of the project's two main web sites. You can read the document at the link here, and after going to that page you need to press on a + button (next to "Expand accordion content") to get the whole text.
The “scientific vision” laid out in the document is largely an ideological vision, based on the unbelievable idea that the human mind is merely the product of the brain. The dubious ideology of the authors is made clear in the very first sentence of the document, in which the authors state, “The human brain is the source of our thoughts, emotions, perceptions, actions, and memories; it confers on us the abilities that make us human, while simultaneously making each of us unique.” It has certainly not been proven that any brain has ever generated a thought or stored a memory.
In fact, later in the document the authors confess, “We do not yet have a systematic theory of how information is encoded in the chemical and electrical activity of neurons, how it is fused to determine behavior on short time scales, and how it is used to adapt, refine, and learn behaviors on longer time scales.” This is certainly true. No one has anything like a systematic theory of how a brain could store memories as neural states, nor has anyone come up with anything like a systematic theory of how a brain could generate a thought. So why, then, did the document start out by stating that “the human brain is the source of our thoughts, emotions, perceptions, actions, and memories”? No one has any business making such a claim unless he first has “ a systematic theory of how information is encoded in the chemical and electrical activity of neurons.” But the document admits that no such theory exists.
But despite this one candid confession, the document was a writing of enormous hubris. The authors boasted that by the year 2025, the BRAIN Initiative would figure out how minds work. The document stated, "The most important outcome of the BRAIN Initiative will be a comprehensive, mechanistic understanding of mental function that emerges from synergistic application of the new technologies and conceptual structures developed under the BRAIN Initiative.” Notice how enormous is the predictive conceit of that statement, which sounds like a delusion of grandeur. The authors did not merely claim that they would "shed light" on how minds work, or that they would "get clues" as to how minds work. They boasted that their project would produce a "comprehensive, mechanistic understanding of mental function." Making a boast as big as the sky. the authors predicted that their project would tell us how brains produce minds and their phenomena.
What has been the result of the BRAIN Initiative? No great breakthroughs have occurred. The results (to use English slang) are "peanuts" or "chickenfeed."
What's going on in the study is a reading of brain waves during very rapid switching between "speak it" instructions and "think it" instructions, with no care being taken to prevent subjects from speaking during the very short "think it" periods lasting only a few seconds. We should assume that during many of the claimed "internal speech" intervals there were actually "audible speech" events, because of a failure of subjects to follow a very hard-to-perform protocol, one seemingly designed to produce such "failure to follow instructions" events. Under such an assumption, the results can easily be explained, without assuming that there was occurring "converting of brain waves into speech." The second of the BRAIN Initiative pages given above boasts that "For one of the two participants, the BCI [brain-computer interface] could decode several words of their inner dialogue with 79% accuracy during an online task." These are meager tiny-sample-size results easily explained by chance or by assuming a difference in muscle movements that produce different types of brain waves, with supposed "inner dialogue" events often being verbal speaking events, as users failed to follow perfectly the hard-to-follow instructions involving rapid switching between speech and pure thinking.
On the same BRAIN Initiative page we have another similar boast of a "brain-computer interface." It is a reference to a paper which makes no claim of picking up an "inner dialogue" involving no muscle movements. Instead some patient with a speech problem had electrodes implanted in his brain, and some system is picking up his attempts to speak different words. Such an attempt can produce limited success mainly because different types of speech efforts (involving slightly different muscle movements) may produce different types of EEG waves. Muscle movements or attempted muscle movements show up very noticeably in EEG brain wave readings; and distinctive types of muscle movements corresponding to particular speech sounds (phonemes) may produce distinctive blips in EEG readings.
Studies like this (hailed as examples of "mind reading" from brains) typically involve a variety of shady tricks, such as getting inputs from more than just brain wave inputs, such as inputs from eye tracking devices, which make it easy to determine what word or picture on a screen someone is focusing on.
The reality is that the BRAIN Initiative has failed to produce any results backing up in any weighty way claims that brains make minds and that brains store memories. You cannot actually detect what someone is thinking from analyzing mere brain waves. Studies claiming to do such a thing typically involve various types of dubious methodology and objectionable techniques. A well-designed, fairly conducted and well-analyzed study will always show a failure to detect from brain waves alone what someone is thinking.
These were additional unfulfilled boasts of the document entitled Brain 2025: A Scientific Vision:
- "We expect to discover new forms of neural coding as exciting as the discovery of place cells, and new forms of neural dynamics that underlie neural computations." So-called "place cells" were never actually discovered. The claim that they were discovered is one of the many groundless triumphal legends of neuroscientists, who have a high tendency to repeat "old wives' tales" of the belief community they belong to. Read my post here for a debunking of claims that "place cells" were ever observed All that happened was that scientists observed some cells, and claimed that some cells were more active when some rats were in certain places. The studies were never examples of robust science, because they were guilty of various methodological sins such as using way-too-small study group sizes. No actual new form of neural coding was ever discovered by the BRAIN Initiative or any other scientific project or scientific study. And no one ever discovered "neural dynamics that underlie neural computations."
- "Through deepened knowledge of how our brains actually work, we will understand ourselves differently, treat disease more incisively, educate our children more effectively, practice law and governance with greater insight, and develop more understanding of others whose brains have been molded in different circumstances." No such bonanza of benefits resulted from the BRAIN Initiative. Neuroscience has done nothing to improve the education of children, and done nothing to improve the practice of law or government.
- "We must understand how circuits give rise to dynamic and integrated patterns of brain activity, and how these activity patterns contribute to normal and abnormal brain functions. Our expectation is that this approach will answer the deepest, most difficult questions about how the brain works, providing the basis for optimizing the health of the normal brain and inspiring novel therapies for brain disorders." The BRAIN Initiative wasted billions floundering around in this dead end, but did not answer any of the "most difficult questions about how the brain works," or any of the "most difficult questions about how the mind works,"
- " We expect The BRAIN Initiative® to develop new biological reagents, possibly including genetically-modified strains of rodents, fish, invertebrates, and non-human primates; recombinant viruses targeted to different brain cell types in different species; genetically-encoded indicators of different forms of neural activity; and genetic tools for modulating neuronal activity." Here the scientists (sounding like eugenics enthusiasts) fall into Frankenstein folly by boasting about how they will monkey with the genes of various organisms, including rodents and primates. The hubris involved here should provoke the gravest concerns. And anyone familiar with the very substantive suspicions that the COVID-19 virus might have arose from a lab leak should shudder at the proposed gene fiddling.
