    Very interesting. My favourite part of all this though is how she comes up with an actually reasonable sounding excuse for why she didn't draw the left, and she kind of refuses to acknowledge that she can't 'mentally see' it. That reasoning part is still very much intact even when she literally can't even draw a daisy properly.

    This is very common in these types of illnesses, her brain refuses to send any signal at all to that section of it, which means she doesn't actually recognise that nothing is being sent, imagine being blind but your eyes dont send the signal to your brain to tell it they cant see anything

    basically her brain was damaged so the visual part of her brain isn't sending signals to her brain that she can't see that side of the daisy, and as a result the conscious side of the brain has to convince herself she is seeing the whole daisy. the communication/speech part of the brain has to come up with a completely untrue response because there is no signals to for her to become consciously aware of what is happening.

    ​@@zoejane1635I would say that more than a visual problem, it is an attention problem. At least, that's what the current updates interpretation is. She can't allocate attention to the left side of her body and environment, no matter what happens in the environment itself (e.g., if an apple falls to the left, your attention would be naturally caught by it, and you would look at it). But when they force her to pay attention, so allocate her attention voluntarily, then, the left field appears to her. Because, again, it's not a visual problem, that would be another condition, which is called emianopsia. All on all, a very interesting condition. Nonetheless, I hope this grandma managed to regain some lost ability, it has to be a struggle to live with...

    What would happen if Peggy was asked to close her eyes, imagine a sunflower, and then draw the sunflower while keeping her eyes closed. Would she draw the sunflower which is complete inside her mind, or will she persist to draw an incomplete version of the sunflower?

    J Spright I think an incomplete version will persist to be drawn. Even in her consciousness, when she thinks of the image, the left side is completely removed and the emptiness is ''filled'' by just attaching the two lose ends of the flower. (Like when you take a paper circle, remove one quarter and try to make the new ends meet). While this would result in a preposterous image in the real world; in her brain, it all makes sense.

    Yes! And in italian sinister is "sinistro" wich is the same word for "sinistra" wich means "left". Left is the part thosee patients neglect. Some hermeneutic interpretation of the condition consider this aspect :) they neglect the sinister in the world.
