Feasibility of mapping the human brain with expansion x-ray microscopy

Posted by in categories: bioengineering, biological, biotech/medical, mapping, nanotechnology, neuroscience

Hey folks, I’m excited to share a new essay with y’all on my proposed route towards nanoscale human brain connectomics. I suggest that synchrotron ‘expansion x-ray microscopy’ has the potential to enable anatomical imaging of the entire human brain with sub-100 nm voxel size and high contrast in around 1 year for a price of roughly $10M. I plan to continue improving this essay over time as I acquire more detailed information and perform more calculations.

For a brief history of this concept: I started exploring this idea during undergrad (working with a laboratory-scale x-ray microscope), but was cut short by the pandemic. Now, I’m working on a PhD in biomedical engineering centered on gene therapy and synthetic biology, but I have retained a strong interest in connectomics. I recently began communication with some excellent collaborators who might be able to help move this technology forward. Hoping for some exciting progress!

Can I Prevent Dementia?

Posted by in categories: biotech/medical, health, neuroscience, singularity

Step one for uploading your brain after the singularity… keep it cognitively functional until then.


It’s been estimated that one in three cases of dementia is preventable. You can’t do anything right now to stop or reverse the underlying mechanisms of Alzheimer’s disease, but you can do something about hypertension and vascular disease risk factors.

Mystical and Insightful Psychedelic Experience May Improve Mental Health

Posted by in categories: biotech/medical, neuroscience

Summary: Recent studies have explored the use of psychedelics for the treatment of a range of mental health disorders. A new study reveals more insightful and mystical “trips” while exposed to psychedelics may be linked to an enduring reduction of symptoms for those with anxiety and depression.

Ben Goertzel — Countering Objections to Mind Uploading

Posted by in categories: cybercrime/malcode, neuroscience

Ben Goertzel in response to some common objections covered in an article on io9 by George Dvorsky ‘You’ll Probably Never Upload Your Mind Into A Computer’: http://io9.com/you-ll-probably-never-upload-your-mind-into-a-computer-474941498

Objections are covered in order as they appear in the article:
1. Brain functions are not computable.
2. We’ll never solve the hard problem of consciousness.
3. We’ll never solve the binding problem.
4. Panpsychism is true.
5. Mind-body dualism is true.
6. It would be unethical to develop.
7. We can never be sure it works.
8. Uploaded minds would be vulnerable to hacking and abuse.

Scientists grow electrodes in brain, thanks to a simple viscous gel

Posted by in categories: biotech/medical, evolution, neuroscience

Blurring lines between man and machine.

A breakthrough has made way for a new paradigm in bioelectronics. Earlier, it took the implantation of physical objects to initiate electronic processes in the body. Humans have incorporated technology to enhance the human experience and take charge of their evolution. They’ve also integrated devices within them that could alternately function as organs when biological tissues fail.

Scientists have now developed a viscous gel that will be enough in the future.
