Dynorphin Modulates Reward-Seeking Actions Through a Pallido-Amygdala Cholinergic Circuit

Dynorphin is an endogenous opioid peptide that primarily acts through κ-opioid receptors (KOR) and is widely involved in the regulation of various behaviors, including reward and aversive responses. However, the specific mechanisms of Dynorphin/KOR signaling in reward-seeking behaviors remain unclear. Previous research has predominantly focused on ...

Basal Ganglia and Related Disorders: From Cellular and Circuit Dysfunctions to Therapy

The Interaction Between A2A Receptor and CB1 Receptor in GABA and Glutamate Release in the Basal Ganglia Background The basal ganglia are key structures in the brain responsible for motor control and reward-based behaviors. They receive excitatory inputs from the cortex and thalamus, with 80% of the synapses being glutamatergic, while the second mo...
