    The reason the neurons all died after the initial seeding is because you didn't rinse the PEI off properly and/or didn't dry it properly. While PEI is the best pre-coating agent in the business, it is also an extremely potent membrane perforant when in solution, so any miniscule picogram of the stuff you left unpolymerized is gonna be jumping from cell to cell, shredding their membranes. Rinse at least five times with maximal volume your growth vessel can take, and dry the vessel overnight in the LAF bench, otherwise you're just wasting expensive reagents.

    I'm a doctoral researcher and Neuroscientist. When it comes to culturing medium for neurons morphology can tell you a lot about the state a cell is in (this goes for most cell types). To me the classic choice of Neurobasal gives you cells with shrunk cell bodies (the nucleus is tightly shrink wrapped if you will) and long complex truncated neurites (dendrites and axons). This tells you that these cells are "mature" neurons. They are not quite mature because you literally need let time pass for them to become mature, interestingly the time of maturation depends on species and is much longer for human neurons compared to mouse neurons.

    • @TheAmazingAnimator
      @TheAmazingAnimator 17 дней назад

      I think that's because rats have less neurons to mature overrall.

    • @christophepetry6782
      @christophepetry6782 17 дней назад +8

      @@TheAmazingAnimator it is more about complexity of their connections and morphology and less about the overall number of cells. In culture you can observe the same time discrepancies between neurons of different species, so it is an inherent quality of the cells.
      We are not clear on what level of consciousness other animals have , since we can’t test for it. You probably mean animals become independent much earlier, since humans literally complete their development outside the mothers body. During evolution our heads got to big for our pelvises so we have to be born “prematurely”.

    9:55 Aha! apropos to my previous comment about cell density, I see how to solve your problems: We always added a small droplet (50-100ul) of cell suspension added to an EMPTY dish, with just a 3mm laminin wet spot. Calculate what density you need in the suspension to get 50k-100k cells in that droplet. After the cells have settled and adhered (30 min?) carefully add the rest of the medium to flood the dish. Now you will have very dense cultures and signals on every electrode.

    My other suggestions seem to have been deleted, perhaps because I linked a paper of ours. I guessed that you may be killing cells with too much light. Phototoxicity is a huge problem with any fluorescence microscopy. To reduce it, use phase contrast (not fluorescence) microscopy and use longer-wavelength (red) light. Also, when doing fluorescence imaging, use a lower-NA lens, more sensitive cameras, dimmer illumination, longer wavelength excitation, and shorter exposure to light.

    • @thethoughtemporium
      @thethoughtemporium  28 дней назад +12

      Feel free to send me an email with all of the suggestions so they don't get lost! And they're greatly appreciated as always.
      We only use phase contrast when checking on the cells. Fluorescence was only used at the end for the sake of the experiment, and the dye was only used on one of the arrays after we had finished all other experiments. The arrays are also only ever left on the microscope for as brief a moment as possible, but the phase contrast images aren't as pretty so I don't use that footage in the video as much.
      I also saw you recommend concentrating the neurons in the middle. I read that in the instructions and that's how we attempted it the first time when the cells died. We went with adding the neurons after the media because we knew for sure the neurons would survive as we've tested that method a lot and couldn't risk another culture dying. We were pressed for time to get the video out. And for our arrays the electrodes are REALLY spread out, so we're gonna need a high neuron density across most of the surface of the array anyway. You'll notice I made the walls of our arrays taller than the multichannel ones. It was specifically because I wanted to increase the amount of growth media per well so the neurons don't deplete it as quickly and to account for an eventual much higher neuron density across the array.
      We have wanted to upgrade our camera on the microscope for a while, but the scope itself was a HUGE upgrade. It's new for this video and it cost a pretty penny. But it's built exactly for this kind of experiment so we can switch out the camera next. I also want to move to a red dye to lower the illumination wavelength as you say. And also just to make the videos look more interesting than always green. We ran out of time, but we also got a tubulin specific dye we're gonna show off next time that would look best against an otherwise red stained neuron. And we picked up NucBlue so we can stain the nucleus properly. One of the shots of the neurons firing included it from the first well we tested it on. I overlaid it. It's subtle but makes the neurons look nicer and the nucleus visible.

Except for machine learning being applicable to organisms, i.e. stimuli training, so maybe we could consider culturing them with positive stimuli for shooting the target before sending them but that sounds like a lot of work.

    I love that the same thing used for FDM 3D printing bed adhesion, PEI, is being used here as a sort of brain bed adhesion. Really interesting work!

      I can't remember today. It is currently happening. I can't remember tomorrow. It hasn't happened yet. Soon I will forget about yesterday.

    Love the content. Every video and experiment is packed with so much information. That to me you are the best biology related channel.

    18:13 don't forget to wrap the wires too, it's how you turn a moderate speaker system in to a high end speaker system.

      The wires look like they might be fiber optic?
      Apart from USB, but that’s error corrected

    How do the neurons "see" the game. That's the part I can't wrap my head around

      The way that it will work is most likely they take the data from the game, asteroid for example, of an enemy being "to the left" and sends signal to a nerve cluster. Cluster then triggers, which tells the left cluster to turn left. Signal is then sent to a different sight cluster that says enemy is "in front" which tells the gun cluster to shoot. Just my guess, same way as us. We receive a signal from eyes that a wall is in front of us, so we don't run into the wall.

    What if we somehow connected neurons to a limb to train it to hold and shoot a gun, so that the neurons could kill a human being.

    Doom is a classic game for testing orgonoids and neurons but ultimately i hope you do create simulation world where all npc are controlled by Orgonoids.
