Circuit Mechanism Underlying Nociceptive Information Processing
Projection neurons in the spinal cord send projections to both sides of parabrachial nucleus (Contralateral: white line; ipsilateral: yellow line). Most of PBN neurons that receive projections from the spinal cord (PBNSC) are located in superior lateral PBN (Red), which send density projections to the intralaminar thalamic nuclei (ILN, Pink line) and few projections to amygdala (Blue thin line). Few PBNSCneurons are located in the external lateral PBN (Blue). This work was published inNeuronon July 8, 2020.
