Abstract

The mechanical properties of brain tissue play a pivotal role in neurodevelopment and neurological disorders. Yet, at present, there is no consensus on how the different structural parts of the tissue contribute to its stiffness variations. Here, we have gathered depth-controlled indentation viscoelasticity maps of the hippocampus of isolated horizontal live mouse brain sections. Our results confirm the highly viscoelestic nature of the material and clearly show that the mechanical properties correlate with the different morphological layers of the samples investigated. Interestingly, the relative cell nuclei area seems to negatively correlate with the stiffness observed.
