Sleep-mediated regulation of reward circuits: implications in substance use disorders
Our modern society suffers from both pervasive sleep loss and substance abuse—what may be the indications for sleep on substance use disorders (SUDs), and could sleep contribute to the individual variations in...

Cocaine-induced projection-specific and cell type-specific adaptations in the nucleus accumbens
Cocaine craving, seeking, and relapse are mediated, in part, by cocaine-induced adaptive changes in the brain reward circuits. The nucleus accumbens (NAc) integrates and prioritizes different emotional and mot...

Cocaine-induced neural adaptations in the lateral hypothalamic melanin-concentrating hormone neurons and the role in regulating rapid eye movement sleep after withdrawal
Sleep abnormalities are often a prominent contributor to withdrawal symptoms following chronic drug use. Notably, rapid eye movement (REM) sleep regulates emotional memory, and persistent REM sleep impairment ...

Chronic sleep fragmentation enhances habenula cholinergic neural activity
Sleep is essential to emotional health. Sleep disturbance, particularly REM sleep disturbance, profoundly impacts emotion regulation, but the underlying neural mechanisms remain elusive. Here we show that chro...

NAD+ cellular redox and SIRT1 regulate the diurnal rhythms of tyrosine hydroxylase and conditioned cocaine reward
The diurnal regulation of dopamine is important for normal physiology and diseases such as addiction. Here we find a novel role for the CLOCK protein to antagonize CREB-mediated transcriptional activity at the...

Cocaine-Induced Synaptic Alterations in Thalamus to Nucleus Accumbens Projection
Exposure to cocaine induces addiction-associated behaviors partially through remodeling neurocircuits in the nucleus accumbens (NAc). The paraventricular nucleus of thalamus (PVT), which projects to the NAc mo...

Cocaine-Induced Membrane Adaptation in the Central Nucleus of Amygdala
Exposure to drugs of abuse lead to both rewarding effects and the subsequent development of negative affects. The progressive dysregulation of both processes is thought to critically contribute to the addictiv...
