Chronic alcohol exposure disrupts top-down control over basal ganglia action selection to produce habits
Addiction involves a predominance of habitual control mediated through action selection
processes in dorsal striatum. Research has largely focused on neural mechanisms …

Bidirectional and long-lasting control of alcohol-seeking behavior by corticostriatal LTP and LTD
Addiction is proposed to arise from alterations in synaptic strength via mechanisms of long-

Pulling habits out of rats: Adenosine 2A receptor antagonism in dorsomedial striatum rescues meth‐amphetamine‐induced deficits in goal‐directed action
Addiction is characterized by a persistent loss of behavioral control resulting in insensitivity
to negative feedback and abnormal decision‐making. Here, we investigated the influence of …
