I think one photon propagating through a human head is surprising. What’s interesting to anyone with an imagination is how ( and why) photons propagate through the brain. We know they’re there, generated by mitochondria, ROS and microtubules themselves due to aromatic dipole.

@StuartHameroff @msahsorin A nice paper deals with the possibility of infrared imaging of the brain. Technical.toue de force. "The combination of high laser power and a large-area single-photon sensitive detector is optimized to overcome the extreme attenuation of light through the head.".

The fMRI BOLD signal occurs after the measureable neural activity. Why? .Cooling is one suggestion, critical for quantum mechanisms.

@StuartHameroff Functional connectivity is junk, it actually measures blood flow and oxygenation, not neural activity.

No. I retired from anesthesia a bit over a year ago and propofol was going strong. It’s a fantastic induction agent, anesthetic, analgesic, anti-emetic and .patients wake up mildly euphoric. It’s henodynamically stable and when properly used is quite safe (Michael Jackson got a.

@StuartHameroff Propofol has come to be disfavored in recent years, apparently for causing cumulative damage. (It seems to have been the only thing that could put Michael Jackson to sleep.).Propofol (as of last time I read into it) combines the effects of benzodiazepines, ethanol & the usual gas.

Wrong x 4. Anirban showed temp independence, entanglement (angular momentum) between separated microtubules, and evidence for microtubule quantum time crystals. And zero phase lag gamma synchrony is classically inexplicable but neuroscientists are in denial. We have a minority.

@StuartHameroff @anirbanbandyo Direct demonstrations of temperature-independent coherence, inter-microtubule entanglement, quantum time crystals, or classically-inexplicable neural synchrony are still lacking. Many of Hameroff’s statements extend beyond what the current literature directly supports.

Very interesting study. LSD caused reduced cortical functional connectivity despite increased measures of psychedelic experience. A recent propofol anesthesia study showed increased cortical connectivity in unconscious patients. This seems backwards.

Thanks. I think the key is the microtubule time crystal idea. Many microtubules entangle so you have one collective time crystal mediating consciousness within the brain. It has self-similar resonance patterns at multiple frequencies, which you mentioned, e.g. megahertz and.

“Absolutely stunning findings, Dr. Hameroff. This paper isn’t just a step forward in neurophotonics — it might be a glimpse into the optical architecture of consciousness itself. That photons can traverse the entire adult human head — through guided cerebrospinal fluid channels,.

Excellent point. Thanks. Orch OR was based on dipole oscillations between/among the electron clouds of aromatic rings inside each tubulin in microtubules because anesthetics act there to block consciousness. But in our 2014 paper we added the possibility of spin coupling along.

Congrats Rudy. What’s your opinion on .Transcranial ultrasound (TUS) for Alzheimer’s? There seems to be a large amount of positive results and basically no adverse effects. Painless, mood-enhancing, inexpensive. Would you collaborate on a clinical study at Harvard? We’re not.

If @AllenInstitute looked inside the pyramidal cell body they’d see the largest array of mixed polarity, anti-parallel microtubules in all of biology. Why interrupted, mixed polarity microtubules only in dendrites and cell bodies of neurons? Recursive processing? Interference.

DYK around half of the brain is not made of neurons? Among the other half is the octopus-like microglia. In this visualization by our Electron Microscopy team, microglia (green) wraps around a pyramidal cell (blue), one of two types of excitatory neurons in the brain.

We will test organic molecules from the asteroid Bennu for quantum oscillations and time crystal behavior. If found we will test effects of Anesthetics and if they inhibit the oscillations proportional to their anesthetic potency we can suggest consciousness was there first. So.

@StuartHameroff Mr. Hameroff, your explanation for the origin of consciousness is the most that makes sense to me. And I'm a pretty logical person. How long will it take for science to confirm his theory? Maybe by 2050.

You’re misinformed. As part of the TWCF competition we predicted we would 1) demonstrate ambient temperature quantum coherence in a microtubule ( we did) and 2) show it to be inhibited by anesthetics (we did). No other theory of consciousness has done that. What’s un falsifiable?.

Problem for you is no other theory of consciousness has any supportive evidence whatsoever. Anirban is just 15 years ahead of you in understanding both science and eastern thought.

@KFosterUPenn @StuartHameroff @anirbanbandyo Anirban Bandyopadhyay is a crackpot who readily engages in pseudo-science. His work in this area has not been replicated and is not credible! Yet Hameroff holds it up in triumph as evidence of his speculative hypothesis.

Photons propagate surprisingly well through the human head, through cortical brain regions it appears. I’d bet the photon path ‘illuminates’ where consciousness is, and where anesthetics bind near quantum optical aromatic pathways. @msahsorin .

Anesthetics actually don’t suppress firing (action potentials, spikes) directly. In fact anesthetics don’t exert their effect on membrane proteins at all!.Here’s a good review.

@DaKingRex1 @StuartHameroff @anirbanbandyo this is speculation! there is no empirical evidence that Anesthesia doesn’t just suppress neuronal firing — it disrupts the quantum coherence within microtubules. You do not seem to understand the scientific method!.

Thanks Rudy. But tangles can arise from tau displaced from microtubules which disassemble, causing loss of neurons, synapses, brain volume and cognition. Don’t tangles correlate more closely with symptoms than does amyloid? Isn’t the primary problem in Alzheimer’s the disassembly.

If you’re referring to Orch OR let’s start with the one thing about consciousness we can measure. What specific brain activity goes away selectively and reversibly with anesthesia?.The answer is quantum effects in microtubules. Regarding the Indian studies, @anirbanbandyo has.

@RandyStout18 @StuartHameroff Could you explain what experimental evidence supports this theory? And how strong is it? The Indian studies that SH keeps mentioning are very weak - not to mention claims about RF being emitted from the head. Are there striking experimental findings that support the theory?.

The neuromodulation in which I’m interested is ultrasound, mechanical megahertz vibrations that seem to promote microtubule polymerization and helps in Alzheimer’s. The point is that microtubules, composed of tubulin the brain’s most abundant protein (the brain is essentially.

How about this one?.The brain functions as a collective time crystal of microtubules coherently resonating at various specific frequencies including megahertz, gigahertz and terahertz. This would account for weak microwaves having biological effects. Please try and refute this.
@KFosterUPenn

@RandyStout18 @StuartHameroff I have spent much of my career dealing with theories for how weak microwaves can affect biological systems. Every year or so a new one appears, which if correct would revolutionize science as we know it. Most fail due to obvious problems, e,g., neglect of dissipative effects.
