Reply to Long-term exposure to even low levels of multiple ambient air pollutants, association with depression, anxiety by 9273629397759992
I did not read the pdf but only the summary. There is a vast ravine separating correlation and causation.
The first thing that occurred to me is that people living in nice traffic free (therefore less pollutants) areas may have other reasons to be happy and not depressed compared to people living in areas of high traffic density and urban density.

I am not a neuroscientist but the experiment and the headlines don't seem to line up to me
The control group had to do the visual task after the strobelight went off at random intervals. It seems like the study is making claims about how strobing visual tasks in synchronization with peaks/troughs of brainwaves improves performance... but the study didn't measure anyone's performance without the strobing to compare against?

Reply to comment by machstem in Planting more trees could axe summer deaths by a third. Modelling of 93 European cities finds that increasing tree cover up to 30% can help lower the temperature of urban environments by an average of 0.4°C and prevent one in three heat deaths as a result. by MistWeaver80
The other great aspect is if you have your tree aligned to provide shade for your windows during the hottest part of the day, it massively cuts down on the amount of heat getting into your home. This reduces the need for active cooling and makes getting to sleep at night far easier and more comfortable.

It's not as professional looking or readable as I'd like because I was in a rush making this way back when, but here it is
https://github.com/raymondem1/Meditation-Lamp
It is pretty much just adjusting this older repository
https://github.com/kitschpatrol/Brain
(And also this one for the data visualization)
https://github.com/kitschpatrol/BrainGrapher
This might be a slightly different version of the same thing that plays meditation music until you are calm but same idea. I'll make it snazzier and easier to read soon

Can you make a github for your setup?

Yes please! Cities are way better with shade. Yards are way better with shade. Pools are way better with shade.

Trees are good. Damage to the environment in the name of corporate greed is bad.

Cities should be designed around public transport and significant green spaces, instead we went the very opposite direction - urban sprawl with new suburbs that have almost no green space baring very small grassy parks

Doesn’t sound new, just newly researched. They said “usually”.

I used a mindflex and hooked the eeg chip up to an Arduino. Then sent in the data through the serial monitor Grab that data and convert it to a 1-100 scale. If the data read higher than the threshold I set before hand (I think I had it at 60 or something) then it meant you were focused which turned on a relay that was also connected to the Arduino which turned on the light. Then the computer just played jimmy neutron whenever this happened. It was actually fairly consistent, so I'm sure doing something kind of similar can replicate the experiment, maybe?

What if throughout the day you keep this flickering thing going that you occasionally check out, would it be able to make you perform better for all that time?

I'm really excited now, first time I'm hearing of this type of EEG, BCI being a possibility and other things. Trying to figure out what I should buy.

Honestly I'm pretty interested in how it will work out. I'll see if I can try to somewhat replicate the experiment just with friends and whatnot. I might have a major placebo so I'll try to make friends test it and whatnot. Now I just have to find friends...(this might be harder than initially anticipated :<)

Do keep us posted. Also interested in what the internal experience is like. As in, can you feel yourself consuming information faster?

I'm no brain expert person but I mean surely they could be used that way. Coding with eeg isn't the hardest thing in the world. I am a very dumb engineer and I was able to use some brainwaves to turn on a lamp when you concentrate (it also played jimmy neutron saying Brian blast). So I think just getting a tempo from those values and doing the same thing with the black box and white background shouldn't be too difficult. I'll try it this weekend and dm you peeps if I can get it working if ya want.
EDIT:
First going to make the thing from the experiment with the whole EEG setup after I wrap up this current project I am about to finish. Then after I recreate the experiment, I'm flirting with the idea of testing to see if something similar would be possible without an EEG chip and just with a free website. Idk if this is possible at all (probably not) but depending on how strict the tempo has to be in sync with brain waves, if there was some kind of way to make your environment get your alpha waves within a certain range (maybe by playing relaxing music or just finding a way to zen out. Again no brain expert but maybe) then you could go off that tempo and have less efficient but still very effective results even without the eeg potentially? Idk a lot of testing will have to go into this but if that works, I would just release this thing for free so quick. (The hardest part of all of this is 100% going to be the testing because I'm not going to post or make anything without testing it 100 times to make sure it actually works well)

Air conditioning in homes is virtually unheard of in the UK, ensuring more places have tree cover will help with dealing with a future where 40C becomes the norm, rather than record breaking.
Not everywhere is like the US.
