Neuropeptide S Attenuates the Alarm Pheromone-Evoked Defensive and Risk Assessment Behaviors Through Activation of Cognate Receptor-Expressing Neurons in the Posterior Medial Amygdala

After unilateral injection of the anterograde multi-trans-synaptic herpes virus H129-H8 into the olfactory bulb, labelled neurons appeared bilaterally in the posterodorsal and posteroventral subdivisions of the medial amygdala 72 h later, which the authors interpret as olfactory input reaching these nuclei; about 90% of the virus-labelled cells in each subdivision also stained for NPSR.
