The claims behind it

Superficial laminae I-II neurons of the trigeminal nucleus caudalis were GFP-labelled after transneuronal pseudorabies transfer from amygdala-projecting parabrachial neurons.

Unlike the pseudorabies experiments, rabies tracing from amygdala-projecting PB neurons rarely labelled trigeminal nucleus caudalis neurons; the authors interpret this as a technical limitation of the rabies vector.
