Parabrachial Nucleus

The nocioceptive-recipient parabrachial nucleus appears to be crucial for the transmission of pain-related information to dopamine neurons. (Coizet 2010). The parabrachial nucleus has 3 major cell divisions - the medial parabrachial nucleus, the lateral prabrachial nucleus, and the kolliker-fuse nucleus (Fulwiler Saper 1984).

Structure

Inputs

-Nociceptive inputs from spinal cord (via lamina I of spinal and medullary dorsal horn) -Ventrolateral NTS, Periambiguous nucleus (Respiratory inputs) -Gustatory inputs (Rostral part of nucleus of solitary tract) -Medial NTS (Visceral) -Area postrema (Chemoceptive)

Outputs

Saper Loewy 1980: pbl_inputs.jpg pbm_inputs.jpg kf_outputs.jpg

Thalamus Hypothalamus Amygdala Bed nucleus of stria terminalis Dorsal raphe nucleus PPTg SNPc, VTA (Note: Most PBN neurons are glutamatergic. Coizet et al suggest that the inhibitory mechanism of PBN may result from PBN outputs onto GABAergic neurons in VTA which could then inhibit DA neurons.)
