At this week’s Consciousness Club we have @svangaal.bsky.social speaking on β€œLinking arousal state fluctuations and recurrent processing to conscious perception”

Looking forward to it!

All welcome, Wednesday 28th Jan 11am-1230pm UK time

#PhiMiSci published a new article in the special issue on structuralism: β€œNeurophenomenal structuralism and the role of computational context” by M. Paßler and A. Doerig.
It aims to challenges local structuralist theories that overlook the content-constituting role of computational context.

Visual representations in the human brain rely on a reference frame that is in between allocentric and retinocentric coordinates Visual information in our everyday environment is anchored to an allocentric reference frame – a tall building remains upright even when you tilt your head, which changes the projection of the building on your retina from a vertical to a diagonal orientation. Does retinotopic cortex represent visual information in an allocentric or retinocentric reference frame? Here, we investigate which reference frame the brain uses by dissociating allocentric and retinocentric reference frames via a head tilt manipulation combined with electroencephalography (EEG). Nineteen participants completed between 1728–2880 trials during which they briefly viewed (150 ms) and then remembered (1500 ms) a randomly oriented target grating. In interleaved blocks of trials, the participant’s head was either kept upright, or tilted by 45ΒΊ using a custom rotating chinrest. The target orientation could be decoded throughout the trial (using both voltage and alpha-band signals) when training and testing within head-upright blocks, and within head-tilted blocks. Importantly, we directly addressed the question of reference frames via cross-generalized decoding: If target orientations are represented in a retinocentric reference frame, a decoder trained on head-upright trials would predict a 45ΒΊ offset in decoded orientation when tested on head-tilted trials (after all, a vertical building becomes diagonal on the retina after head tilt). Conversely, if target representations are allocentric and anchored to the real world, no such offset should be observed. Our analyses reveal that from the earliest stages of perceptual processing all the way throughout the delay, orientations are represented in between an allocentric and retinocentric reference frame. These results align with previous findings from physiology studies in non-human primates, and are the first to demonstrate that the human brain does not rely on a purely allocentric or retinocentric reference frame when representing visual information. ### Competing Interest Statement The authors have declared no competing interest.

Check out our *preprint* for some cool correlations with behavior (for foblique effect fans). For now, I’m just happy that these fun data are out in the world. It’s been a minute Chaipat Chunharas & I ventured to dissociate allocentric and retinocentric reference frames (7+ years ago?! 🀫)... 10/n

Very good indeed. @stevefleming.bsky.social thinks consciousness is a process - what something does. In that case he says it’s theoretically possible for AI to be conscious. Not so, says @anilseth.bsky.social.
