Epigenetic Target HDAC5 Reduces Environment-Triggered Cocaine Seeking in Rats
In a rat model, overexpressing the enzyme HDAC5 in the prelimbic cortex shifted synaptic balance to suppress context-driven cocaine seeking.

NMDA Receptor Ablation in Adolescent Mice Triggers Synaptic Rebound
Removing NMDA receptors in the adolescent mouse prefrontal cortex causes an initial spine loss followed by a compensatory synaptic rebound.
