✦ Synopsis

The effective stress concept in geomechanics advocated by Terzaghi is historically reviewed and the mechanical interpretation of this concept is clarified based on the theory of mixtures. In the interpretation of the effective stress concept, both the compressibility of the constituents and the balance of force are taken into consideration. The effectiveness of the effective stress comes from the fact that the descriptions of the effective stress in undrained and unjacketed conditions are approximately equal, although the role of the pore-water pressure under different test conditions is not the same. It is shown that the effective stress concept is also applicable to soft rock. Finally, classical interpretations and various definitions of the effective stresses are critically examined.

## Abstract The basolateral amygdala (BLA) has been repeatedly shown to mediate the effects of stress on memory‐related processes. However, the way in which stress influences BLA itself has not been fully explored. We studied the effects of stress and corticosterone (CORT) on activity and plasticit
