Early-Life Stress Exerts Long-Lasting Effects Via Epigenome
Asher Jones | Mar 18, 2021 | 5 min read
In mice, epigenetic marks made on histones during infancy influence depression-like behavior during adulthood. A drug that reverses the genomic tags appears to undo the damage.
New Genes, New Brain
Cristina Luiggi | Oct 19, 2011 | 2 min read
A bevy of genes known to be active during human fetal and infant development first appeared at the same time that the prefrontal cortex—the area of the brain associated with human intelligence and personality—took shape in primates.
