BLN (basolateral amygdaloid nuclear complex) projects to CEA (central amygdaloid nucleus)

All claims for this connection
Species
Rat
Result
present
Method
retrograde tracer
Sign
unknown
Evidence
A subset of CTB-labelled BLA neurons projecting to the CeA also expressed the CRHR1 reporter, showing that CRHR1-expressing BLA cells send axons to the CeA; the share of CeA projectors expressing CRHR1 exceeded that of NAc projectors.
Measurements
  • fraction of labelled neurons: 0.1343, n = 8
