Have you ever wondered why mental images aren't as vivid as real images? And what's the difference between imagining something and hallucinating it?

CW: Vividness of mental imagery, aphantasia
This paper from 2020 by Rebecca Keogh, Johanna Bergmann and Joel Pearson shows that electrical manipulation of the excitability of neurons in the prefrontal and visual cortices can be used to temporarily increase or decrease vividness of mental imagery (at least for people with some visual imagery): https://doi.org/10.7554/eLife.50232
Mike Perrotta provides some background, and makes the research a little more accessible for the layperson in this 2021 article for the Aphantasia Network: https://aphantasia.com/article/science/shocking-insights/
