NTS (Nucleus of the solitary tract) synapses onto PB (Parabrachial nucleus)

Species: Mouse
Result: ambiguous
Method: transsynaptic tracer
Sign: unknown
Evidence: Rabies tracing from amygdala-projecting PB neurons seldom labelled solitary tract nucleus neurons, in contrast to the pseudorabies result; the authors attribute this negative finding to a limitation of this rabies strain rather than to absence of the connection.
