Accumulating evidence indicates that the laterodorsal tegmental nucleus (LDT) is associated with reward processing and addiction. The cholinergic projection from the LDT to the ventral tegmental area is essential for a large dopamine release in the nucleus accumbens, which is critically involved in the reinforcing effects of addictive drugs, including(More)
The laterodorsal tegmental nucleus (LDT) is a brainstem nucleus implicated in reward processing and is one of the main sources of cholinergic afferents to the ventral tegmental area (VTA). Neuroplasticity in this structure may affect the excitability of VTA dopamine neurons and mesocorticolimbic circuitry. Here, we provide evidence that cocaine-induced(More)
Although the involvement and plasticity of the mesocorticolimbic dopamine (DA) system in cocaine-induced addiction have been studied extensively, the role of the brainstem cholinergic system in cocaine addiction remains largely unexplored. The laterodorsal tegmental nucleus (LDT) contains cholinergic neurons that innervate the ventral tegmental area (VTA)(More)
The laterodorsal tegmental nucleus (LDT), which sends cholinergic efferent connections to dopaminergic (DA) neurons in the ventral tegmental area (VTA), plays a critical role in the development of addictive behavior and the reinstatement of cocaine-seeking behavior. Although repeated cocaine exposure elicits plastic changes in excitatory synaptic(More)
