As the first author of that paper, I approve of this link.

While it's not a fixed function pipeline, there is some level of correlation between 'brain damage at site x' and 'effect y' so while phrenology is bunk, the brain is also not just a blob of compute.
The central thesis is excellent, but this really caught my eye: > Depression is usually catalogued as a mental illness, but it’s as much a metabolic illness as cardiovascular disease, which itself has significant mood-related symptoms. These two diseases occur together so often that some medical researchers believe that one may cause the other. That perspective is steeped in Cartesian dualism. Both depression and car…
I wish this to be true. I'm in excellent cardiovascular health - low BP, 60 bpm resting heart rate, extensive cardio/endurance activity 4-5 days per week. Utterly miserable every waking hour.

You do realize what you're proposing happened and happens extensively?
I've read a decent chunk of that research, but it's often relegated to backwater low-reputation journals focused on alternative medicine and is largely ignored by mainstream science. For an example, see the research on various traditional sleep-inducing drugs. It also doesn't make its way into mainstream practice among GPs and psychiatrists. As an example, which mainstream practitioner would ever prescribe or recomme…
I wouldn't say that the Triune brain theory is a 'myth'. It's just not accurate, but it's not a complete lie either. There certainly are different parts of the brain that have evolved at different times, and have different functions. The older parts have evolved to specific functions, while neocortex, which is found in mammals, has a uniform structure and is capable of learning and adapting to different tasks. 75% of…
Brodmann distinguishes 47 or so different areas in the cortex. Idk how many are exclusive to the neocortex, but it's not a uniform structure.

That to me is really how we need to be emphasizing education in science for young people. We tend to give the impression that we’ve figured almost everything out, and so you’re just learning the facts of it all. Really, we’ve carved out a little island in a sea of ignorance, and the foundations of the island are just our current best rough approximations that might collapse. An example from the field I’m in — biology…
The major questions of biology have already been solved, though. The rest is filling in the details.
We also have some grand principles that further unite the field, like the cell as the basic unit of organismal life, emergent properties of higher order systems, &c.
The remaining work is mostly 'stamp collecting' - looking at the details of the output of that algorithm. Of course those details are enormously complex. Kind of like mapping out the Mandlebrot Set after you already know the algorithm.

My above comment was not ironic. What I meant is that we have already discovered the algorithm that gives rise to all biological phenomena: Evolution by Natural Selection.

If you wanna cure cancer, resolve chronic diseases, conserve ecosystems under climate change, etc.
It’s cool to know that DNA exists and that life evolves by natural selection, but getting into the complex weeds of that fractal is where we discover that we know so little.
