  • Always exciting to learn about new perspectives on consciousness!

    I have searched for the “Cellular Basis of Consciousness (CBC)” theory and I do not personally find it very compelling. I appreciate that the hard problem of consciousness is very difficult to address using the scientific method, but I suspect that consciousness arises from a form of processing that requires computations of the kind performed by animal brains. I don’t think that the kind of biophysics that allows cells to sense and respond to the environment are enough to create a conscious experience.

    About the: “third state”. Cells are alive, independently of the multi-cellular organism that they come from. I don’t agree that changing the way that the cells are organized constitutes some “third state”.

    Despite my disagreements, it is still nice to read and think about. Thanks for sharing.




  • Even though:

    These data are associative and do not establish a causal role for such particles affecting health

    I still don’t feel so nonchalant about the idea of microplastics lodging on my brain. While the effect on human brains is very difficult to directly measure, we do have a lot of data on mice that suggest that having plastic in the brain is bad for the brain.

    When quickly looking into EU food regulations it seems like microplastic content is not regulated in food, and the logic appears to be along the lines that not enough data is available to assess the actual risk. This makes some sense in that measurement, control, and enforcing limits is likely to be difficult, expensive, and might create some economic challenges, and so regulators might not want to go this route unless proven absolutely necessary.

    At the same time, data does exist showing that the plastic levels are increasing in our brains, and we have very good reasons to believe that this is not a good thing. It is not that we are completely in the dark - I am sure some smart people would be able to come up with reasonable limits and methods of control by now.

    My not-very-informed suspicion is that there is pressure from wealthy and powerful lobbyists that would significantly suffer from microplastics regulations, because ‘plastic in the brain’ has seemed like an obvious thing to address for some years now.

    I have never been educated about how to avoid ingesting / breathing microplastics. Do any of you know some habits or diets that reduce or increase exposure to microplastics?


  • I think that panspermia is the most likely hypothesis to be eventually proven correct.

    According to this hypothesis, very simple “living” structures can be found throughout space, scattered around planets, meteorites, and perhaps even in space dust. This dust can be thought of as fungal spores. When they land in a planet with suitable conditions, these systems can evolve into more complex life forms.

    The alternatives to panspermia generally imply that Earth is a super special planet in which certain special conditions conspired at a point in time to allow an extremely unlikely event to happen. Panspermia suggests that, instead of a being a statistical anomaly, life is probably rather common throughout the universe.
