Understating the function of neural circuits and the state-depended adaptations within them is one of the fundamental aims in the field of neuroscience. With recent technical developments in monitoring circuit dynamic, such as calcium (Ca2+) imaging, visualizing synaptic connections using viral approaches and manipulating neuronal activity in cell-specific manner such as optogenetic and chemogenetics, we are now able to mechanistically link the activity and function of neural circuits with behavioral outcomes.Using the above-mentioned techniques, I demonstrate that pain induces somatic adaptations in the Ventral Tegmental Area (VTA) dopamine (DA) neurons to drive anhedonia-like behaviors. Pain is a complex phenomenon composed …
