DOI: 10.1002/jdn.10243
Abstract: Gestational hypothyroidism is a prevalent disorder in pregnant women and also impairs fetal development with relevant outcomes. One of the outcomes of greatest interest has been rodent fear‐ and anxiety‐like behavior. However, the relationship between… read more here.

DOI: 10.1007/s00221-021-06116-6
Abstract: Dopamine seems to mediate fear conditioning through its action on D2 receptors in the mesolimbic pathway. Systemic and local injections of dopaminergic agents showed that D2 receptors are preferentially involved in the expression, rather than… read more here.

DOI: 10.1016/j.biopsych.2017.03.020
Abstract: BACKGROUND Hippocampal concentrations of the neurotrophic factor fibroblast growth factor 2 (FGF2) are negatively associated with the expression of fear following conditioning in rats. Heightened conditioned fear expression may be a prospective risk factor for… read more here.

DOI: 10.1016/j.brat.2017.01.017
Abstract: Extant literature suggests that extinction training delivered during the memory reconsolidation period is superior to traditional extinction training in the reduction of fear recovery, as it targets the original fear memory trace. At present it… read more here.

DOI: 10.1016/j.brat.2022.104051
Abstract: Heightened generalization of conditioned fear and avoidance to safe stimuli resembling threat is a key feature of pathological anxiety and might contribute to the increased prevalence of anxiety-related disorders among women. Though animal studies have… read more here.

DOI: 10.1016/j.expneurol.2020.113306
Abstract: Reduction of conditioned fear expression by extinction underlies cue exposure therapies that treat anxiety disorders. Extinction is context-specific. Renewal, for example, is the relapse of extinguished fear when subjects are tested in a different context… read more here.

DOI: 10.1016/j.pnpbp.2018.11.007
Abstract: &NA; Endocannabinoids (eCBs) anandamide (AEA) and 2‐arachidonoylglycerol (2‐AG) were shown to be involved in the basis of trauma‐induced behavioral changes, particularly contextual conditioned fear, however, their ligand‐specific effects and possible interactions are poorly understood. Here… read more here.

DOI: 10.1038/s41593-018-0248-4
Abstract: The formation and retrieval of conditioned fear memories critically depend on the amygdala. Here we identify an inhibitory projection from somatostatin-positive neurons in the central amygdala to parvalbumin-positive neurons in the zona incerta that is… read more here.
