Journal ArticleDOI
Socioeconomic status and the developing brain
TL;DR: These studies indicate that SES is an important predictor of neurocognitive performance, particularly of language and executive function, and that S ES differences are found in neural processing even when performance levels are equal.
Journal ArticleDOI
Lasting epigenetic influence of early-life adversity on the BDNF gene.
TL;DR: An epigenetic molecular mechanism potentially underlying lifelong and transgenerational perpetuation of changes in gene expression and behavior incited by early abuse and neglect is highlighted.
Journal ArticleDOI
Transcription Factors in Long-Term Memory and Synaptic Plasticity
TL;DR: The results of this work suggest that patterns of transcription regulation represent the molecular signatures of long-term synaptic changes and memory formation.
Journal ArticleDOI
Histone acetylation: molecular mnemonics on the chromatin
TL;DR: As histone acetylation and cognitive functions can be pharmacologically restored by histone deacetylase inhibitors, this epigenetic modification might constitute a molecular memory aid on the chromatin and, by extension, a new template for therapeutic interventions against cognitive frailty.
Journal ArticleDOI
Finding the engram.
TL;DR: This Review develops four defining criteria that enable us to critically assess the recent progress that has been made towards finding the engram, and proposes that findings from 'capture' studies represent considerable progress in allowing us to observe, erase and express the engrams.

Nongenomic Transmission Across Generations of Maternal Behavior and Stress Responses in the Rat
TL;DR: Results of cross-fostering studies reported here indicate that variations in maternal care can serve as the basis for a nongenomic behavioral transmission of individual differences in stress reactivity across generations.

Sustained hippocampal chromatin regulation in a mouse model of depression and antidepressant action

TL;DR: An important role for histone remodeling in the pathophysiology and treatment of depression is underscored and the therapeutic potential for hist one methylation and deacetylation inhibitors in depression is highlighted.

A mouse Mecp2-null mutation causes neurological symptoms that mimic rett syndrome
TL;DR: The overlapping delay before symptom onset in humans and mice raises the possibility that stability of brain function, not brain development per se, is compromised by the absence of MeCP2, and generates mice lacking Mecp2 using Cre-loxP technology.
Journal ArticleDOI
DNA methylation-related chromatin remodeling in activity-dependent BDNF gene regulation.
TL;DR: It is reported that increased synthesis of brain-derived neurotrophic factor in neurons after depolarization correlates with a decrease in CpG methylation within the regulatory region of the Bdnf gene, suggesting that DNA methylation–related chromatin remodeling is important for activity-dependent gene regulation that may be critical for neural plasticity.
Journal ArticleDOI
Solvent Mediated Interactions in the Structure of the Nucleosome Core Particle at 1.9 Å Resolution
TL;DR: A single-base-pair increase in DNA length over that used previously results in substantially improved clarity of the electron density and accuracy for the histone protein and DNA atomic coordinates, and reduced disorder has allowed for the first time extensive modeling of water molecules and ions.
