> In the past, I might have said to her, “Dying is natural; it’s part of the human experience,” but without this experience, it would not have landed well. She had to feel this in her whole person, not just as an intellectual or philosophical exercise.

This seems to be a big part of the magic of psychedelics. So many mental issues are cognitive. It’s not always happening at the chemical level. Why would it be in a person who has a healthy brain, but their depression came on with their terminal cancer diagnosis?

The problem is cognition is really hard to change. Especially in adults and especially when things are going badly. The overall effectiveness of talk therapy is not great.

Psychedelics break down our normal barriers so we can truly know the things other people have been telling us and we’ve been telling ourselves. (Or they put us in contact with spirits that gift wisdom. Six of one, half a dozen of another). I talked with someone with OCD who finished a trip thinking “just because my hand touches my phone doesn’t mean it’s dirty”. A simple statement, but he had contact OCD and this had been a huge problem. Something about the message “coming from inside the house” made it work.

One thing I almost never see mentioned in these articles about terminal patients with psychedelics is the concept of the afterlife. Mushrooms are so Earthy, it’s like they tell you that heaven is returning to the soil. Other psychs (DMT, ayahuasca) can give you a picture of where your spirit goes after it splits from your body.

Aside from whether these spiritual beliefs are right they’re certainly less depressing than what the average American is walking around with. There’s “sleep and never wake up”. There’s “heaven, maybe, I think. But lots of people going to hell I guess”, and then, probably the most common case: “who the fuck knows?”. A bit anxiety inducing, really.




>So many mental issues are cognitive. It’s not always happening at the chemical level.

As a biochemist with a passion for neuroscience, I entirely 100% do not agree

The statement doesn't even make sense to me. All cognition is based on the dynamics happening at the biochemical level. All of it is chemical

All of our thoughts and behaviors are the product of chemical reactions and interactions which determine the behavior of individual neurons and their networks. You literally cannot separate those things.


Humans have longed relied on metaphor and analogy to provide context. Chemistry is a contextualized generalization of certain physical phenomena.

Neurons are just temporal spatial events of various mathematical parameters; gradients and ranges of heat, light, etc.

Everything is some form of “how matter happened to coalesce relative to light during $arbitrary_date_time_range”

Or it’s all the specialized language of chemistry and biology.

Six to one, half dozen to another. Normalizing the descriptions isn’t proof of correctness, it’s a specific normalized set of glyphs to simplify communication.


My issue simply stems from how people try to disconnect our conscious experiences from the physical phenomena that underlies it.

Perhaps its my own perception on how I read into statements that make these assertions, but humans have quite a long history of invoking magic "souls" and such to explain thought processes and behaviors. My insistence on referencing the underlying phenomena is an attempt to counter this.


so well said.

there’s absolutely no reason, for example, as to why unitive consciousness as described in some Hindu philosophies would be in contradiction with our experience of cognition originating entirely within a chemical framework of understanding reality.


Yes it all happens as chemistry. I mean the cause of the problem isn’t always what we would normally call “chemical”. That’s what I meant by “happening at the chemical level”.

I’m just drawing a distinction between something like depression caused by a B12 deficiency and depression caused by the loss of your spouse. Thinking can’t fix B12, but sometimes it helps with loss.

If I try to word it better, would you agree that sometimes mental health issues are caused by biological problems and sometimes by events in our lives and how we think about them?


I'm not sure I could agree with that. What I could agree with is a statement that live events can alter our epigenetic regulation mechanisms which impacts our neuronal chemistry which can alter our thought processes and behaviors.

At the end of the day its still chemistry, and at the end of the day chemistry is still physics, and as far as I've learn physics is deterministic. We can't separate our conscious experience from these underlying mechanisms because our entire existence is based on their rules. The brain is not a construct on which the software of the mind runs, it is the mind.


I’m not claiming that consciousness is separate from chemistry or the mind is separate from the brain.

You could call every problem you run across a physics problem, since our world operates under the laws of physics. That’s just not a particularly useful way to go about things.

If I got fired from my job for a reason I thought was unjust, I’d be angry. And if someone saw me being angry and asked a third person why I’m angry they might say “he got fired for a bullshit reason”. This is all totally normal stuff. They wouldn’t say “his sympathetic nervous system is elevated”. That really doesn’t help the other person understand what’s going on.

Now if I have a tumor that’s smashing my amygdala, then expressing the problem in terms of chemistry/biology is helpful.

I brought this split up at all because it can be useful in figuring out how to treat illness. I think we get it wrong often. There are people in talk therapy who should get on meds to lower their heart rate, and there are people on depression meds who need to switch jobs. (And all of this vice versa).

You seem to be latched onto a specific claim I don’t even think I’m making. Could you engage with the heart of what I’m saying (the usefulness of cognitive changes in treating mental illness and how psychedelics help) and iron man my argument?


I went back and reread your original comment, and I may be a bit confused.

You state that issues are cognitive but then go on to discuss how psychedelics break down barriers. Psychedelics are drugs, one of the best ways of showing that out cognitive processes are determined by our neuronal chemistry.

Considering a traditional psychedelic like 4-HO-DMT or LSD, these compounds have activity at a few different serotonin receptors (and some other side interactions). This pharmacological activity (interaction of an external compound with our internal biomolecules) is how psychedelics alter our cognitive processes.

From my perspective, this shows how our cognitive processes are biochemical and using a drug can change it easily whereas other means are more difficult such as external sensory inputs (therapy, talking to people, reading, aromatherapy, massage?)

I entirely agree with the usefulness of psychedelics, they are massively powerful tools. They're great at helping catalyze significantly alterations in our thought processes, but these changes that they help induces are chemical and structural (structural such as changes in synaptic connectivity)

Structural changes between neurons are directed by chemical signaling as well.

If the changes that fix the problem are biochemical, the problem was biochemical. We alter the biochemistry and they induce changes in the emergent properties of the overall system: behavior and thought processes

Our thought processes and behaviors are the product of our brains (and some signaling from other organs, mostly the brain though) and even minor changes in certain areas or with certain regulatory mechanisms can have profound impacts on mental health.


> They're great at helping catalyze significantly alterations in our thought processes, but these changes that they help induces are chemical and structural (structural such as changes in synaptic connectivity).

Psychedelics don’t operate purely this way (it is part of it). They also, through chemistry, create an opportunity for change in cognition. It’s common for people taking psychedelics in a therapeutic context to leave with lasting insights (like in the article). I don’t know this to be true of any other drugs. SSRIs don’t have the “and then I realized” moment.


The change that they create an opportunity for in cognition is a change in regulation and structure at a biochemical level


Yes, I agree. There are also some important details.

1. That state is short. Minutes or hours. 2. That state is different from the long changes. 3. The long term effects can be enhanced by the activities you do during the temporary state, including thinking. 4. Long term effects can be enhanced and maintained by non-drug activities.

This whole setup seems to be especially good at curing illnesses that are caused by something “at the cognitive level”. It won’t do much for anxiety caused by a hyperactive gland. It will for anxiety caused by a fear of death.


Those long changes are chemical. Its all chemical

Cognition operates on the basis of neuronal dynamics and neuronal dynamics operate on the basis of biochemical interactions

All changes in neuronal dynamics are due to changes in biochemical regulation

Fear of death could be caused by a multitude of reasons, it's not as simplistic as you make it sound. People are innately afraid of death because there are pathways and regulations that occur naturally in our brain development driven by genetic biochemical regulation.


In case it helps, I think the original post was not meaning to say that the mind is not chemically based in the brain. I did not see it as a contradiction in their position.

I think their use of "chemical" was part of an assumed dichotomy between chronic disorders referred to in pop-culture as "chemical imbalances" versus other (learned or cognitive behavioral) disorders which could presumably be unlearned. The difference is mirrored in the assumed intervention: whether a continuous maintenance dose of some drug is needed to manage the chronic condition versus a transient dose or other therapy which allows the brain to assume a healthier posture and maintain itself thereafter.


> What I could agree with is a statement that live events can alter our epigenetic regulation mechanisms

For sure they can, and we also get to choose our reaction to said events.

This debate is ancient. Do we have free will, or are we predestined to fate? Knowledge of chemistry and physics doesn't give an answer to that question.


Even though we know our computers are "all electrical" in nature, don't we admit that there are software/state problems which can exhibit themselves even if every part of the computer is functioning correctly as an individual electrical component? You cannot find the broken part to fix which will resolve the problem that emerges from an unfortunate set of values stored in the circuits.

I think that is the metaphorical mapping intended by the earlier poster, that a problem can be cognitive rather than chemical.


I think the distinction in this case is that software is not an emergent property that directly arose from the mechanisms of circuits.

Neurons are different than circuits, as their chemistry and physiology does change with various inputs. That's actually how a decent portion of the computation happens.

My disagreement is with the fundamental assumption that the brain is just hardware on which the software of the mind runs. This is not accurate at all, the chemistry and physiology of the brain is everything


You and I might agree on the nature of the mind, in a metaphysical sense. But, the nature of mind is mostly immaterial (ha!) for this topic. The original poster was arguing that a new depressive state as a result of a traumatic diagnosis is evidence that it is a learned or acquired state, rather than something congenital and fixed in physiology. They further argue that this means the sufferer might be guided to unlearn or re-learn to a more desirable state. It may be an optimistic perspective, but I don't think physical reductionism invalidates it.

The computer metaphor is of course shallow or simplistic. It's not meant as an all-explaining allegory. The relevant part, which you even allude to yourself, is that state changes in the brain can be effected through "inputs". The only thing we need to consider is whether further sensory inputs and thought processes can continue to affect the state. Unless you are arguing that the brain reaches some terminal and irreversible state, I don't see that there is any real conflict here.

As an aside, as a computer scientist, I will tell you that software is exactly an emergent property of the circuits. Put another way, software is an abstraction we place on it, as observers. It is not really there as the machine operates. The physics and structure of the machine are likewise everything, with physically real states changing as a result of microscopic mechanisms integrating local state and some signals carried in from topologically neighboring mechanisms.


I think we have a different perspective on emergence, although what you say brings up something I enjoy thinking about.

Software is made by humans on top of the circuits we designed. My perspective on emergent properties is to view it as a spontaneous process arising without intervention.

I think its possible to view silicon computation and software as an emergent property if we consider humans to be part of the natural system out of which software emerges.

Thinking about how we fit into natural systems and considering our role in the development of systems of material, energy, and information exchange. What we develop and build could be considered an emergent property of the universe when a planet has the right constituents, temperature, etc.


Yes.

I don't consider causal intention to be part of the definition of emergence. Whether through spontaneous evolution or engineering, I think any complex system likely has emergent properties or phenomena. To me, emergence is broad and includes everything from the cascading order of an avalanche to flocking behavior of birds or the standing waves in the morning rush hour; the chill under a clear night sky to cooling effects of perspiration or the heat pump in my refrigerator.

My take on emergence is that it is deeply mired in observation. A complex system does complex behavior. An observer recognizes patterns of behavior and forms an abstraction of identity to distinguish a certain pattern as a characteristic of the system. In some observer-less sense, the complex behaviors are certainly there. But, the semantic boundaries of what is a behavior, what identifies it as a persistent thing that can have emerged or not depending on the current state of the system... those are illusory concepts declared by the observer.


What I took away from GP was that this medicine helps a person learn and integrate truths that their current neuropathways may be blocking or inhibiting at a subconscious level. It's a neuroplasticity aid of sorts and less of something to be taken as a long term maintenance medication. The change in perspective in a therapeutic setting can be a catalyst to permanent changes in thought patterns.


Neuroplasticity is controlled with chemical signaling. Thought patterns are determined by synaptic connections and biochemical regulation


Have you read up on cognitive behavioral therapy? A short summary would be that a lot of it is caused by entrenched thought patterns and toxic routines. So a question of what input you process how. Its often not caused by chemical imbalances but what falsehoods you belief and what conclusions you draw from it.


"Chemical imbalances" is a terrible way of describing what causes some mental health issues. Its an issue with regulation and sometimes it can be changed with something like CBT.


Thanks for the correction, i am obviously not familiar with the field. This was meant as an example of non-chemical cognition problems.


So theoretically you could know what your wife wants for dinner by solving the Schrödinger equation?


Essentially, yes. Although we don't fully understand the system so we can't model it just yet


The comment you're replying to simply describes emergence.


Emergence still depends on the underlying mechanisms


please share sources that definitively prove that all cognition is the product of chemical reactions?


Its rather surprising to me that you're asking this in a thread about the strongest evidence we have for cognition being biochemical.

The evidence is that action of psychoactive drugs, especially psychedelics and anaesthetics. We have compounds that we have studied that actions of and they act on neurons and their networks to alter or eliminate cognition.


I hear that you are surprised.

I understand there is data that supports this theory; I wasn’t aware that it is definitive nor how easily it could be reproduced.

Before it was edited, your original statement framed certainty about cognition originating in chemistry as a personal belief. Which isn’t a scientific statement.


I don't believe I edited the comment that you're replying to.

Edit: as a side note, general anesthesia is used hundreds or thousands of times daily and it always eliminates or reduces cognition. That's literally the whole purpose of using it


I just came across this -

kinda fascinating…


My apologies, I thought there was an edit where you said you firmly believed this.

Interesting point re: GA.
