Acoustic waves used to determine softness of brain matter

摘要

A team of researchers have measured how soft brain matter really is. By recording how fast an acoustic wave travels in the intact brain of a pig, the researchers were able to determine that brain matter is extremely soft, even softer than common gelatine. The study by researchers from Tsenghua University in Bejing and Professor Michel Destrade, School of Mathematics, Statistics and Applied Mathematics at NUI Galway, Ireland appears in Biomechanics and Modelling in Mechanobiology.
