2020 Journal of Cognitive Neuroscience  
Here, we report the first in vivo study of human hippocampal subfield viscoelastic stiffness and damping ratio.  ...  Moreover, damping ratio of the CA3-DG-potentially reflective of number of cells and their connections-predicted relational memory accuracy and alone replicated most variance in performance that was explained  ...  Acknowledgments This study was partially supported by National Institutes of Health (NIH)/National Institute of Mental Health Grant R01-MH062500, NIH/National Institute of Aging Grant R01-AG058853, and  ...
