Neuronal activity in #SensoryCortex correlates with #perceptual decisions, but does this reflect causality? This study shows that LFP frequency bands dissociate causal & non-causal signals; high-gamma reflects causal, lower freqs contextual @PLOSBiology https://plos.io/3SeJv7f

RE: Whether it rests on key modulation - or, #keymodulation as a #SongWriting device, #popsong device, neck-massaging device. I haven't picked up the #guitar yet to figure it out, but i think i'm wrong: at least the timeline referenced. It's not modulation, but (Having not picked up the instrument) I believe it is "borrowed chords", as in borrowing chords from another key which is not necessarily analogous to modulation, and certainly-- potentially-- much more complicated!
Clearly
not-knowing
now bugs-me.That's definitely a #piano #songwriter's song. Songwriter is a pianist. Elton John tunes are like that. In my #perceptual experience, in retrospect, I recall feeling that way about Kurt Cobain, the chord changes in nirvana songs (McCartney & Lennon, etc.).
That is to say, it's about the #melody you "hear" and the way it "sits in the chord" so to speak (the chord, which you also "hear" probably).
You can change those chords n shit.
People call that Jazz. Is that correct? That's i dunno.
Led Zeppelin?
Otherwise, it's Er!c Cl@p⸸on's bastardization of "the blues"; a "I , IV , V" (or make-it-fancy w/ a vi and a iii) an A-B-A-B-C #progression, or the other one.
Stray from the first inversion for a less "familiar" way of penetrating the ear hole. Like, "the stranger". Sitting on hands -
[en] Are natural faces and facial #deepfakes perceived and remembered in the same way?
"... we investigated the most studied process of face cognition: perceptual matching and #discrimination of facial identity ... identity discrimination of natural and synthetic faces is governed by the same underlying perceptual mechanisms ..."

New #paper alert! Camila Bruder, David Poeppel (@ESI_Frankfurt), and Larrouy Maestri find that "#Perceptual (but not #acoustic) features predict #singing #voice preferences". Out now in #ScientificReports: https://www.nature.com/articles/s41598-024-58924-9

Effect of perceptual training with sound-guided and kinesthetic feedback on human 3D sound localization capabilities https://www.mdpi.com/1424-8220/23/11/5023 "accuracy in full 3D sound localization can be improved based on training", "relative error feedback is more effective than absolute error feedback". #blind, #perceptual #training

#Design for #Neurodiverse #Inclusivity:
#Invisible challenges include: #autism spectrum; learning challenges; developmental challenges; and #MentalHealth. What role does the #BuiltEnvironment play in #disabling these user groups? How can we, as built environment practitioners, learn from this #diverse #perceptual model? How can we design in a way that is more #facilitative, #supportive and #accessible for #neurodiverse perceptual models?

A review on different applications of control ideas to neuroscience, #motorcontrol and #decisionmaking, using in particular #controltheory and #perceptual #control.
The description of perceptual control seems suspiciously close to Friston's #activeinference...

Perceptual #illusions, the misinterpretation of sensory input, are common in several neurological & #psychiatric disorders; @josipa_alilovic &co show that such illusions have both #perceptual & #cognitive neural origins in the human brain #PLOSBiology https://plos.io/3SMB1jM

#Videohash is a #perceptual #hash for #video.
Videohash computes 64 bit hashes of videos such that similar videos produce similar hashes. Videohash does this by scaling videos to a uniform size, then running a wavelet hash over the frames. Hashes are robust to scaling (including aspect ratio changes), transcoding, watermarking, colour changes, etc. Videohash is weak against rotation and flips, however.
