- Reposted by Jordy van LangenI had such a blast presenting the last project of my PhD for a flash talk and a poster at #Flux2025 Grey and white matter are not two separate tissues and we found that adversity is associated significantly differently with grey and white matter measures showing the importance of looking at both!
