Protein kinase M[zeta] (PKM[zeta]) maintains long-term potentiation (LTP) and long-term memory through persistent increases in kinase expression. Early-life adversity is a precursor to adult mood and anxiety disorders, in part, through persistent disruption of emotional memory throughout life. Here we subjected 10- to 16-wk-old male bonnet…

Debnath, Ranjan; Tang, Alva; Zeanah, Charles H.; Nelson, Charles A.; Fox, Nathan A. – Developmental Science, 2020
Exposure to early psychosocial deprivation as a result of institutional care disrupts typical brain development. The Bucharest Early Intervention Project (BEIP) is the first longitudinal study to investigate the neurodevelopment of institutionalized infants randomized to a foster care (FCG) intervention versus care as usual (CAUG). Here, we…

Cohen-Gilbert, Julia E.; Stein, Elena R.; Gunnar, Megan R.; Thomas, Kathleen M. – Journal of Early Adolescence, 2018
This study investigated whether brain-derived neurotrophic factor (BDNF) genotype moderated inhibitory control during an emotionally valenced task in a sample of internationally adopted adolescents (N = 109, ages 12-13 years) who spent their early years in institutional care. Participants were genotyped for the Val66Met polymorphism of the BDNF…
