07.02.2025 21:01 โ ๐ 0 ๐ 0 ๐ฌ 1 ๐ 013/ Perhaps a couple more invasive ones, for example, how can you sleep with this in your head? And how to wear a hat?
07.02.2025 21:01 โ ๐ 0 ๐ 0 ๐ฌ 1 ๐ 012/ Looks brutal(Johnny mnemonic 1994). This and the matrix are my favorite loaded designs (lots of wires, hardware and other stuff)
07.02.2025 21:01 โ ๐ 0 ๐ 0 ๐ฌ 1 ๐ 011/ This is opposite, good style, you can see right away that only the frontal lobes are needed (Surrogates 2009) I also think this is a reference to Schwarzenegger's BCI from the movie 6th day
07.02.2025 21:01 โ ๐ 0 ๐ 0 ๐ฌ 1 ๐ 010/ Want to dive into VR and become a genius in your garage? This is Lawnmower Man movie, pure trash
07.02.2025 21:01 โ ๐ 0 ๐ 0 ๐ฌ 1 ๐ 09/ Back to the early OPM era, the bulb lights inside make everything cooler pls add them to real MEG
07.02.2025 21:01 โ ๐ 0 ๐ 0 ๐ฌ 1 ๐ 08/ Brainstorm (1983) - this according to the plot records experiences and memories, cool and stylish but I have a question why two staples on the sides?
07.02.2025 21:01 โ ๐ 0 ๐ 0 ๐ฌ 1 ๐ 07/ It's a head drying or maybe brainwashing, who knows, but it looks cool for 50s

07.02.2025 21:01 โ ๐ 0 ๐ 0 ๐ฌ 1 ๐ 05/ My top 1, legend from Ghostbusters, you can still make pasta using this
07.02.2025 21:01 โ ๐ 0 ๐ 0 ๐ฌ 1 ๐ 04/ According to the description from neurafutures.com, most often such devices are used in science fiction to control memory or transplant consciousness. Well, I don't think that anyone is working on this now, but what is definitely cool in these films is the design of the devices. Below is my top
07.02.2025 21:01 โ ๐ 0 ๐ 0 ๐ฌ 1 ๐ 03/ As a database I used bciwiki.org/index.php/Br... add some info from the excellent project www.neurafutures.com and also posts on Reddit and from my own memory (cool device photo starting from 5/ )
07.02.2025 21:01 โ ๐ 0 ๐ 0 ๐ฌ 1 ๐ 02/ Well, quite a few movies use BCI or something similar, and I didn't include magical objects like the sorting hat from Harry Potter
07.02.2025 21:01 โ ๐ 0 ๐ 0 ๐ฌ 1 ๐ 01/ There is a private cinema museum in Lyon, the owner collects various artifacts from movies. Among them is a part of Johnny Depp's (fake) head with electrodes from the Transcendence. I wondered how often BCI devices like this are used in sci-fi films and series (and my own top of them below)
07.02.2025 21:01 โ ๐ 0 ๐ 0 ๐ฌ 1 ๐ 020/ More important that, predictive coding was able to elegantly combine perception, learning, and attention (and sensory attenuation) into one model. Also while it did change the idea of โโwhat a neural signal is, we're still 25 years later trying to figure out how exactly error signals are encoded
31.01.2025 19:01 โ ๐ 0 ๐ 0 ๐ฌ 0 ๐ 019/ So what about the strange inversion? From my point of view It wasn't really a real inversion from stimulusโcognitionโresponse towards prediction. Although the concept of predictive error was new to psychology and neuroscience
31.01.2025 19:01 โ ๐ 1 ๐ 0 ๐ฌ 1 ๐ 018/ Finally, there were no studies pointing to suppression in the visual cortex, a key element in pioneer predictive coding papers. For example see, Predictive coding: A fresh view on inhibition in the retina (1982) and Rao & Ballard's work, both mention end-inhibition neurons
31.01.2025 19:01 โ ๐ 0 ๐ 0 ๐ฌ 1 ๐ 017/ Additionally, the mathematical foundation were not on the table (like in 90s). Ideas related to optimal information processing, developed within cybernetics and information theory, only emerged in the 60s-70s (when a New Look approache was drowned in criticism).
31.01.2025 19:01 โ ๐ 1 ๐ 0 ๐ฌ 1 ๐ 016/ Also because many early cognitive psychologists in the 50s-60s were reluctant to work with "set," which was seen as a garbage term tied to psychoanalysis and Gestalt psychology. New Look failed to formalize this correctly
31.01.2025 19:01 โ ๐ 0 ๐ 0 ๐ฌ 1 ๐ 015/ I think this happened because it was the simplest interpretation of experimental results (e.g., faster reactions to expected stimuli and slower to unexpected ones) Occam's razor slaughtered the theory's growth
31.01.2025 19:01 โ ๐ 0 ๐ 0 ๐ฌ 1 ๐ 014/ These concepts assumed โdirective factors, given a stimulus input of certain characteristics, operate to organize the perceptual field in such a way as to maximize percepts relevant and expectations and to minimize percepts inimical to such needs and expectationsโ
31.01.2025 19:01 โ ๐ 0 ๐ 0 ๐ฌ 1 ๐ 013/ What's even stranger is that the opposite happened. New Look proponents developed concepts like Perceptual Defense and perceptual vigilance.
31.01.2025 19:01 โ ๐ 0 ๐ 0 ๐ฌ 1 ๐ 012/ Even experiments from the 20th century, like Bruner & Postman's card experiment, closely resembled the oddball paradigm, a classic in predictive coding?
31.01.2025 19:01 โ ๐ 0 ๐ 0 ๐ฌ 1 ๐ 011/ So, describing the 20th century solely as stimulusโcognitionโresponse is inaccurate. But why didnโt we get a fully developed precursor theory of predictive coding 50 years earlier? After all, the "set" also includes prediction
31.01.2025 19:01 โ ๐ 0 ๐ 0 ๐ฌ 1 ๐ 010/ And apparently for quite a long time, Gibson's 1941 classic review of the "set" concept revealed that, with its almost infinite subdivisions (mental set, motor set, neural set, etc.), including ideas like "neurotic anxiety," "incubation process in reasoning," "time error in psychophysics."
31.01.2025 19:01 โ ๐ 0 ๐ 0 ๐ฌ 1 ๐ 09/ It also pointed out that the concept of โsetโ was a โtraditional wastebasket construct until recentlyโ (mid-70s article).
31.01.2025 19:01 โ ๐ 0 ๐ 0 ๐ฌ 1 ๐ 08/ article A new look at the new look: Perceptual defense... 1974 shows : โIt is not particularly instructive... to review the various studies showing that expectations about input do indeed affect thresholds... for this would be merely to document the existence of a well-accepted phenomenon.โ
31.01.2025 19:01 โ ๐ 0 ๐ 0 ๐ฌ 1 ๐ 07/ They also clearly stated: โits perception represents a violation of expectationโ and โwhen well-established expectancies fail of confirmation, the organism may face a task of perceptual reorganization.โ
31.01.2025 19:01 โ ๐ 0 ๐ 0 ๐ฌ 1 ๐ 06/ For instance, Bruner & Postman in their 1949 paper On the perception of incongruity: A paradigm wrote: โIt is a truism worth repeating that the perceptual effect of a stimulus is necessarily dependent upon the set or expectancy of the organism.โ
