Transcriptome profiling of the ventral pallidum reveals a role for pallido-thalamic neurons in cocaine reward

AbstractPsychostimulant exposure alters the activity of ventral pallidum (VP) projection-neurons. However, the molecular underpinnings of these circuit dysfunctions are unclear. Using RNA-sequencing followed by circuit-specific gene expression assays, we revealed a key role for the VP to mediodorsal thalamus (VP-MDT) projection neurons in cocaine-related behaviors in mice. Our analyses demonstrated that the transcription factor Nr4a1 bidirectionally modulated dendritic spine dynamics in VP-MDT neurons and positively regulated pathological drug use.
