We could all use some extra stress #resilience rn. But how does it work in the brain? On the surface, resilience looks like ignoring stress. Does the brain fail to respond? Or are active adaptations required? Or are resilience and susceptibility divergent paths? doi.org/10.1016/j.celrep.2025.116867

Congratulations to Rebekah Rashford and team, it’s finally out! We tagged early life stress-activated neurons in VTA and found that chromatin those cells was much more open, even into adulthood, and that open CREs predicted greater gene expression in response to stress later in life rdcu.be/eLa9z

Have not yet read yet, but it looks like there is a detectable, but weaker, DA reward response? Could there be homeostatic mechanisms that compensates for the weak DA release, in the event of genetic/other perturbations to the DA system, given how important it is for learning ;)?
