A cortical hierarchical mechanism for subjective visual experience during working memory https://www.biorxiv.org/content/10.64898/2026.04.08.717338v1 On mental imagery, #aphantasia; "the cortical hierarchy from IPS to EVC is critical for conscious mental visualization of memory content during WM maintenance"; #neuroscience
"Rather than dysfunctions in a single brain region, we identified a breakdown in feedback along a cortical pathway from the intraparietal sulcus (IPS) through area V3AB to the early visual cortex (EVC) in #aphantasia."
Apparently the mind's eye is working by re-using for recollection the neurons primarily used for sight. But what does it reveal on the causes of #aphantasia? Do we have any clue? https://nautil.us/the-biological-basis-of-imagination-1279716

The Biological Basis of Imagination: Probing the mind’s eye

I don’t see images in my head. Can training give me a mind’s eye?

Training programmes for people with aphantasia – the inability to create mental images – are challenging neuroscientists' understanding of how we create thoughts

I feel kind of stupid right about now. I just realized that I have a form of #aphantasia. I knew what that was but I thought „I can rotate 3d objects in my mind so I don’t have that.“

Turns out, that is not actually visual imagination, that is entirely spatial.

When I imagine a scene in my mind, I feel the masses of objects and how they move in space, but there are no details at all. đź« 

No wonder the only way I can draw anything from imagination is by using construction on paper and iteratively refining what I have already put down.

Seeing is part of creativity. I dumped 2 #necklaces I had made onto the table ... how many would the ensuing flowing shape grab their attention? I am kind of forced to observe by my very emotional mind! And key is that my #aphantasia makes me very sensitive to things in the real world that I cannot conceive of in my head.
Oh honey, if you're having problems explaining how you want a multi-dimensional matrix of information to be 'presented', just imagine how little I understand it when I can't visualise anything you're describing. #aphantasia

My recollection from undergrad, decades before the term "aphantasia" was coined, is that B.F. Skinner testified to not having a mind's eye, thus declared it not to be a thing for anyone.

From what am seeing of reviews of Nick Chater, also a behaviorist, and author of The Mind is Flat, he might also be an aphant who believes his own lived experience to be reflective of everyone else's.

It sounds like ideas myself held, around the time first heard the anecdote about Skinner. This being the first clue that Skinner's experience, per the anecdote, that my experience, was somehow outside the norm.

Such ego-centric introspection (for evaluating how one's thought processes work, to declare that they are not as rich as others claim thought processes to be, is still introspection) can lead to very limited models of mental phenomena.

Andreesseen might also be an aphant who doesn't know any better.

Given how the classic awakening of aphants is "Wait, you mean others really do see pictures in their heads?! That's not just a metaphor? They really see things in their heads!?!?!?" behaviorism can sound quite appealing, as its failure to explain mental phenomena we don't experience doesn't stand out as a weakness.

Eventually, many of us learn that our experience of the world is not dispositive. Not all of us do.

Attached: 1 image Pardon the everything app screenshot but the self-immolation of Andreessen is a sight to behold He got so upset that people call him out for his “I don’t have feelings” tweet that he is storm-posting about how he is not bothered and definitely has no feelings or any inner self
