Re: Open Source Watch

I highly recommend it. The professor is one cute little genius. Check this presentation of hers for a taste of what you're up 'against':

http://youtu.be/WpoQSN2VpbQ

This course allows one to finally update what most people learn about genetics (and when I say 'most' I'm already referring to the actual few who 'actually' learn anything at all), even in the biomedical and pharmacochemical sciences... Not that I particularly enjoy knowing more than most per se (alright you got me =P) but it is just that most people are pretty ignorant.. or are they?

So, if you want to discuss this stuff, I'll be right here WAITING (lol), I sorely need a refreshment.. : ) tho i can't be bothered to redo the course itself unless I'd be going "all in" (which I rarely do, and all-in biology is due only next decade in my schedule : )).. I mean, reading everything et al, maybe even checking out exams and what not... Following the white rabbit I barely have time now anyway, as I head towards my 80th MOOC! 'O.õ ... But I'll be glad to discuss this topic with you.

Oh dear! Oh dear! I shall be too late!

Hi open-source-watchers  :  )
Two very well known works currently sitting on youtube:

Ivan Illich's classic 'Deschooling society', free audio book:
http://www.youtube.com/watch?v=2eDObYpbbzs

Also John Holt's 'Instead of education', discussion:
http://www.youtube.com/watch?v=no6UEQjBUF0

They have distinctly different approaches, but both interesting.

Re: Open Source Watch

btw, I should note I'm against exams (in and of itself). In my "all-in" perspective I mentioned, I would treat them as a game, but "even then" (a term I used previously as well) it is doubtful I would play that one, since I (we?) already have more efficacious methods of interacting and committing data to LTP ^_^

This post is not about that however, it is useful and on-topic (in and of itself), before you feel tempted to delete or move it : ) [though we can fire up a conversation if you guys want, though probb more appropriate elsewhere]

This is about another great "open source watch" project, from CERN:

https://protonmail.ch/

Truly encrypted mail (don't store text so no use even if hacked ;-)), now you guys can have privacy without worrying I may be reading'em all =D I mean... the No Secrets Allowed agency of course, I'd never do that.. or are they? [or would I?]

The demand has been so high however (can you blame them?), that we have to wait a bit for more hardware to be allocated. But I believe you good people can still get your short, personal, nicknames of your preference =) [at least all my previous emails had to include either a bunch of numbers or be long or have some hard to distribute initials or something].. there is a "check availability" button there to facilitate this.

"An asthma drug has rejuvenated rat brains, making old rats perform as well as young rats in tests of memory and cognition. The drug also encouraged the birth of new brain cells."

of course preventing the inflammation in the first place might be a better plan of action.....

Re: Open Source Watch

Hi dudes,
The drug under consideration is a leukotriene receptor antagonist marketed as 'Singulair'

Neuropsychiatric events have been reported in adult, adolescent, and pediatric patients taking SINGULAIR. Post-marketing reports with SINGULAIR use include agitation, aggressive behavior or hostility, anxiousness, depression, disorientation, disturbance in attention, dream abnormalities, hallucinations, insomnia, irritability, memory impairment, restlessness, somnambulism, suicidal thinking and behavior (including suicide), and tremor.

Re: Open Source Watch

Yeah probably not.   
“rejuvenated and new neurons grown”  is what caught my eye.   I was intrigued that this readily available drug could be a tool for neurohacking.
In reading the article, the effect is seen only as repair of damage (likely due to inflammation) and not augmentation.  Hence, the best plan of action would be to prevent whatever is causing the inflammation in the first place.   Like the article here   http://neurohackers.com/index.php/en/me … g-research  which talks of alternate day fasting for asthma.

What can be taken away from this article, is that the processes that cause asthma also cause neurological damage.
I do not fully understand the mechanism of this drug, but it is possible that if it allows rejuvenation of known damage, then a temporary course of treatment could be beneficial despite the side effect risks.  If it only accelerates repair that would occur anyway once the inflammatory processes are removed, then maybe not.


Note:  I had meant to post this topic in Mainstream Watch, not Open Source Watch so please move if possible.

Hi dudes,
Just in:

H Lifestyle use of drugs by healthy people for enhancing cognition, creativity, motivation and pleasure
L-S Camilla d'Angelo, George Savulich, Barbara J Sahakian
Accepted manuscript online: 20/04/2017

Today there is continued, and in some cases growing, availability of psychoactive substances, including treatments for mental health disorders such as cognitive enhancers, which can enhance or restore brain function, but also ‘recreational’ drugs such as novel psychoactive substances (NPS).

The use of psychoactive drugs has both benefits and risks: whilst new drugs to treat cognitive symptoms in neuropsychiatric or neurodegenerative disorders could have great benefits for many patient groups, the increasing ease of accessibility to recreational NPS and the increasing lifestyle use of cognitive enhancers by healthy people means that the effective management of psychoactive substances will be an issue of increasing importance.

Clearly, the potential benefits of cognitive enhancers are large and increasingly relevant, particularly as the population ages, and for this reason we should continue to devote resources to the development of cognitive enhancers as treatments for neurodegenerative diseases and psychiatric disorders, including Alzheimer’s disease, attention deficit hyperactivity disorder (ADHD) and schizophrenia.

However, the increasing use of cognitive enhancers by healthy individuals raises safety, ethical and regulatory concerns, which should not be ignored.
Similarly, understanding the short-and long-term consequences of NPS use as well as better understanding the motivations and profiles of users could promote more effective prevention and harm reduction measures.


Lots of useful info in this one! Full paper in Drugs & Chemicals section of NHA library

enjoy,

Discovered through this article
https://www.newscientist.com/article/21 … ucination/

I haven't read (all of*) them yet, but many of the titles sounded of interest to neurohackers.

*Edit:
Anyone interested in lucid dreaming might like this paper.

http://open-mind.net/papers/what-is-the … e-research
It describes states experienced during lucid dreaming, and also the use of 25Hz and 40Hz tACS to stimulate and increase control of lucid dream states.

"Memory for Prediction Error Minimization: From Depersonalization to the Delusion of Non-Existence"

Interesting (and amusing) title. Let's see if they got it right..

Loading.. Please wait.


Cool! Although I see no mention of 'Golden Rule #1' there. (as per usual in psycho-related studies) I'd suggest said 'further investigations' control for Zinc content in diet and absorption.

Nice collection, thanks.

Open source brain simulator, versions for Windows/ Mac / Linux

http://www.thevirtualbrain.org/

Individual patient data allow researchers to study brain function using detailed simulations
February 2, 2018
Using patient measurement data, researchers from Charité - Universitätsmedizin Berlin and the Berlin Institute of Health have refined a brain modeling platform called the Virtual Brain. The software has been used in projects and publications across the globe. The latest findings have been published in eLife.

The task of deciphering the brain's functions and complex structure demands the acquisition of vast amounts of data from many sources. Like the pieces of a jigsaw puzzle, these data then need assembling into computer simulations that allow researchers to understand the mechanisms involved in brain function. Created with this objective in mind, the Virtual Brain is capable of combining the measurements of an individual patient to produce personalized models. The software acts as a "mathematical microscope," allowing researchers to reproduce interactions between nerve cells that cannot be directly measured in humans. This method makes it possible for researchers to use brain signal data to draw conclusions about interactions between the neuronal networks producing them. Launched in 2012 as an open-source simulation platform, the Virtual Brain is an international project led by Prof. Dr. Petra Ritter (of the Department of Neurology with Experimental Neurology) and two of her colleagues from Toronto and Marseille.

Researchers from Prof. Ritter's BrainModes Group have developed a new approach involving the use of a type of EEG headset to record measurable brain electrical activity from the scalp surface. The data thus obtained are later integrated into a personalized computer model, which simulates brain activity normally only measurable with the use of a large MRI scanner. In fact, this model was able to calculate six different features of brain activity. Previous attempts in animals had required invasive procedures but produced only partial results. The new model was able to produce detailed descriptions of the manner in which these processes contribute to specific brain functions, thereby confirming the hypothesis that the inclusion of EEG data in the computer model produces more detailed simulations of brain activity. By allowing researchers to depict brain processes with enhanced spatial and local resolution, EEG data make them easier to understand.

"This new method of brain simulation allows us to combine theories of how the nervous system works with physical measurements and integrate them into a single comprehensive model that is both physiologically and anatomically grounded," explains Prof. Ritter. In many of the natural sciences, this type of approach has proved extremely useful in hypothesis formulation and testing. However, the use of patient data to produce individualized models represents an entirely new development and has the potential to uncover individual differences in the way the brain works, both in patients and in healthy subjects.

The next step will be to study larger groups of patients, in the hope of deciphering the mechanisms underlying conditions such as epilepsy, stroke and dementia. Summarizing her current research, Prof. Ritter says, "This software has the potential to directly benefit patients. A clinical study currently underway in France is studying how this technology might help improve outcomes in patients undergoing epilepsy surgery. The neurosurgeons involved are able to optimize outcomes by first simulating the procedure using a virtual version of the patient's brain."

Soon, the Virtual Brain may also benefit the wider population. The BrainModes app, developed at Charité for use with smartphones and tablets, works with commercially available neuro-headsets to enable users to become better acquainted with their own brains. Under the leadership of Prof. Ritter, the Charité-based researchers will develop this technology further, in the hope of one day being able to control machines, computers and exoskeletons via brain interface.

Why we developed a microscope for your phone – and published the design
February 21, 2018 by Antony Orth, The Conversation

My colleagues and I have developed a 3-D printable "clip-on" that can turn your smartphone into a fully functional microscope.

We've released the design online so that anyone can print it and modify it to suit their needs.
But why?
For a lot of medical diagnostics, you need to look at small stuff – down to the level of individual cells. To do that, you need a microscope.

There's been a push over the past decade or so by scientists and engineers to bring diagnostics into the home, and to other areas where you can't really bring traditional lab equipment.
Scientists are hoping that this will allow them to, for example, detect malaria and other blood-borne parasites in the field in Africa.

And the backbone of a lot of portable medical diagnostic devices is a mobile phone-based microscope.

A good place to start
You may not think of your mobile phone as being anything like a microscope, but it has almost all the parts you need. The lens and camera sensor are arranged exactly as they would be inside a microscope – all you need to do to get some magnification is stick another lens in front.
The next part is to think about how you are going to illuminate your sample, which is often just as important as the lenses you use.

The engineering involved to assemble these mobile phone microscopes is not trivial, however. You often need a decent amount of skill and a lab to be able to put these devices together. We wanted to see how simple we could make a microscope, meaning the fewest extra parts and assembly steps possible.

Guiding the flash
We figured that it made a lot of sense to use the internal flash in the camera to light up your sample. The challenge is that the flash points in the wrong direction – you need to turn it around to shine through the sample and into the camera.

Redirecting light like this usually requires something fancy like a mirror or a prism. But we realised that the flash on a phone is so bright we can just use the diffuse reflection (glare) off regular plastic. So we designed the clip to have a series of tunnels that confine light and turn it around to face the sample and camera.

A lot of light is absorbed by the 3-D printed resin of the clip, which is black. But it's not perfectly black, and even the tiny fraction of light that makes it through the tunnels and reflects off of the black surface is more than enough to light up a microscopic sample. And that's it – no mirrors, prisms or illumination lenses are needed.

Light and dark
Next, of course, you need something to look at. The local pond is a good place to start. Put some water on a slide or in a capillary tube and you will find many cool-looking microorganisms going about their lives.

This type of illumination is called bright-field microscopy. But we actually went a bit further, and showed that you can turn the flash off and use the Sun to perform dark-field microscopy—where the specimen is lit up, but the field around it is dark.

The clip is designed in such a way that sunlight (or ambient room light) gets trapped in the glass sample slide, and can only be redirected into the mobile phone camera if it hits an object in the sample. If the sample slide is empty, the background is dark (hence dark-field). If there is an object it shines bright on the dark background, and as such this is a great way to detect really subtle objects such as cells (which are mostly water) sitting in water.

What we're hoping is that our design, or something like it, gets used for ultra simple, cheap and robust mobile phone based devices – be it for medical diagnostics in underserved areas such as the remote Australian outback and central Africa, or monitoring microorganism populations in local water sources.
We've released the design online so that anyone can print it and modify it to suit their needs. This part is important because the mission of low-cost microscopy is to ease access to this high tech equipment. This is best accomplished when everyone has the opportunity to make one for themselves or to adapt it freely.

The clip can be printed using any 3-D printer—we prefer the Formlabs family of printers—and you'll need black resin. The cost in resin per clip is typically a couple of dollars at most. You'll also need a lens to put in the clip. We buy ours from an online retailer and then remove the lens from the camera module.
