Hi @elduvelle_neuro! In vivo histology exploits the sensitivity of certain quantitative MRI (#qMRI) measures to biological tissue properties such as myelin density, iron content, or neural fibres. I work with human data, but research on chimpanzees, macaques, mice and rats is also available.
I recommend this review if you would like to learn more: https://www.nature.com/articles/s42254-021-00326-1. Authors @NikWeiskopf, @LukeJoelEdwards and @MR_Siawoosh are also on Mastodon.
Feel free to reach out if you have any further questions!
