mitthrowaway2: Is there a case for non-dystopian applications for such a project, should it succeed?I get that we're all driven by curiosity, and the brain is very mysterious, but at some point I really wonder when scientists will start to taboo projects like this for ethical reasons, just like they currently taboo human cloning.
td2: I dont know anything about neurosience But if dreaming is related enouth to visual perception, maybe a dream recorder might be somewhat possible
aspenmartin: Dystopian applications are extremely impractical or impossible, this is a tool for neuroscience
smusamashah: There was this research where faces were almost perfectly reconstructed from money's brain signals. How were they able to achieve such perfect recreation from monkey but not even close from human brain.https://www.bbc.co.uk/news/science-environment-40131242
pixl97: "This will never be used by bad guys" says the person immediately before their tools are used by bad guys.
aspenmartin: No, it's "this tool cannot be used by bad guys or good guys, but can be used by highly funded labs that do neuroscience". It's something that freaks people out until they gradually learn what is actually involvedhttps://ai.meta.com/blog/brain-ai-image-decoding-meg-magneto... [2023] https://ai.meta.com/blog/brain-ai-research-human-communicati... [last year, focuses on decoding text]^ There's a research team at Meta that studies this. You need an MEG -- thats $2-5M + the shielded room it lives in and the experts that can operate it.EEG doesn't work due to low spatial resolution and how finicky it is to place the electrodes to get a good signalThe signals from neurons are just unbelievably tiny and are in an absolute sea of noisy trash. No one is ever going to read your thoughts without your consent (or by wrestling you into a big MEG, in which case you have bigger things to worry about). No one is going to be reading your dreams with any sort of accuracy either.
mandolingual: And computers used to fill a room and require stacks of punch cards to use.
aspenmartin: in both cases: physics decides what's possible
itisit: > How were they able to achieve such perfect recreation from monkeyBecause the macaque study didn't decode faces from fMRI. They first used fMRI to locate the face patches, then used tungsten microelectrodes for single-unit electrophysiology to record spikes from individual face-selective neurons in ML/MF and AM. [0]Single-unit recordings capture individual spike patterns at a resolution fMRI, which averages across hundreds of thousands of neurons per voxel, simply cannot provide.[0] https://pmc.ncbi.nlm.nih.gov/articles/PMC8088389
r_klancer: Well, well, then I have a paper for you (2014); https://www.frontiersin.org/journals/computational-neuroscie...You might be interested in author #7. Some guy named Dario something.
