ZI (Zona incerta) projects to PAG (Periaqueductal gray)

All claims for this connection
Species
Rat
Result
present
Method
retrograde tracer
Sign
unknown
Evidence
After CTb injections into the dlPAG, the A13 group in the medial zona incerta held the most CTb/TH double-labelled neurons of any dopaminergic group in every case. They were mostly ipsilateral and concentrated in the intermediate A13.
Measurements
  • fraction of labelled neurons: 0.6, n = 1
  • fraction of labelled neurons: 0.5, n = 1
  • fraction of labelled neurons: 0.59, n = 1
  • fraction of labelled neurons: 0.45, n = 1
  • fraction of labelled neurons: 0.78, n = 1
