Bernabe CS, Caliman IF, Truitt WA, Molosh AI, Lowry CA, Hay-Schmidt A, Shekhar A, Johnson PL. Using loss- and gain-of-function approaches to target amygdala-projecting serotonergic neurons in the dorsal raphe nucleus that enhance anxiety-related and conditioned fear behaviors. (2020) J Psychopharmacol 34(4):400-411. doi: 10.1177/0269881119900981
Objective: To investigate the role of amygdala-projecting 5-HT neurons in the DR in innate anxiety and conditioned fear behaviors.
Summary: The studies support the hypothesis that amygdala-projecting 5-HT neurons in the DR represent an anxiety and fear-on network.
Dose: Each rat received two bilateral microinjections per site (100 nL each, 1 μM in ACSF) of either Anti-SERT-SAP or the control Mouse IgG-SAP.

Objective: To elucidate the role of these serotonergic networks on learned fear and innate panic responses.
Summary: LED excitation or lesioning of PeF projecting 5-HT system respectively attenuated and enhanced panic-associated escape/flight behaviors and cardioexcitation following a 7.5 and 20% CO2 challenge.
Dose: Anti-SERT-SAP was injected into the BLA or PeF to lesion these 5-HT pathways.

Summary: Serotonin may affect how mothers perceive or behaviorally readjust to changes in the sensory cues emitted by their offspring as they age. The DR serotonin-lesioned mothers studied by Holschbach and colleagues (2018) were much less maternally aggressive, which was concomitant with reduced serotonin-immunoreactive fiber density in the anterior hypothalamus, a brain site previously implicated in serotonin’s influence on aggressive behaviors in male animals.

KIT-23: Anti-SERT-SAP, Mouse IgG-SAP
Objective: To determine the effects of behavioral modifications associated with early motherhood by permanently disrupting serotonin signaling at one of its primary sources, the dorsal raphe (DR).
Summary: Prepartum serotonin-specific lesions of the DRdm impaired maternal aggression. Larger postpartum DR serotonin lesions affected both aggression and caregiving. DR serotonin lesions did not affect postpartum anxiety,
Dose: 1 μL of 0.1M anti-SERT-SAP or control Mouse IgG-SAP was slowly infused into the DR.
