| Agree. It's incredibly frustrating seeing takes on science by engineers on HN. It's as bad as, if not worse than, the takes I see about politics around here. For context, this is what the paper itself says: > In order to experimentally assess the contribution of
MTs as functionally relevant targets of volatile anesthetics, we measured latencies to loss of righting reflex (LORR) under 4% isoflurane in male rats injected subcutaneously with vehicle or 0.75 mg/kg of the brain-
penetrant MT–stabilizing drug epothilone B (epoB). EpoB-treated rats took an average of 69 s longer to
become unconscious as measured by latency to LORR. This was a statistically significant difference
corresponding to a standardized mean difference (Cohen’s d) of 1.9, indicating a “large” normalized effect
size. The effect could not be accounted for by tolerance from repeated exposure to isoflurane. Our results suggest that binding of the anesthetic gas isoflurane to MTs causes unconsciousness and loss of purpose-ful behavior in rats (and presumably humans and other animals). This finding is predicted by models that posit consciousness as a property of a quantum physical state of neural MTs. > Our study establishes that action on intracellular microtubules (MTs) is the mechanism, or one of the mechanisms, by which the inhalational anesthetic gas isoflurane induces unconsciousness in rats. This finding has potential clinical implications for understanding how taxane chemotherapy interferes with anesthesia in humans and more broadly for avoiding anesthesia failures during surgery. Our results are also theoretically important because they provide support for MT-based theories of anesthetic action and consciousness. Let me emphasize: > This finding is predicted by models that posit consciousness as a property of a quantum physical state of neural MTs. If people here want to criticize the paper, I want to see some citations of passages from the fucking paper, and not some hur-dur quote from a popular science article meant to convey the paper to a lay audience. But you know, 99% of the paper would be indecipherable to most people here, so all we get is these surface level takes that wastes everybody's time. The intellectual laziness in these comments is galling. |
My issue with the ScienceDaily and even the original eNeuro article isn't with individual quotes, but with the apparent motivated reasoning of the papers. I'm generally aware of the field quantum-consciousness, Orch OR, and with Penrose's theories. I'm also aware of the funding/publishing methods in science and this looks a bit weak. The evidence is, we didn't find another mechanism. That there had to be corrections on supporting research, which included the names of additional funders (Templeton Foundation) is also not a wonderful sign (if you know you know).
The actual article research covers the effect of epoB on tolerance and latency of anesthesia in rats, which support the action of isoflurane on microtubules (MT) as at least one mechanism. There is a bunch of other stuff about quantum consciousness that reads like a review paper. Quantum is mentioned 58 times and plays no role in their actual measurement or results.

I actually didn't find the paper that hard to read, it's mostly basic science and huge review of Orch OR. I don't consider it a big prestigious journal, and I don't recognize names on it, but the actual results (limited as they are) don't seem outrageous or unsupported. I'm also not sure they're that interesting unless you already have a fringe theory to support.
