recommendations! Published in 2025 at "Journal of Applied Toxicology"

DOI: 10.1002/jat.4845

Abstract: Bisphenol A (BPA), a prevalent endocrine‐disrupting chemical used in plastic manufacturing, has been progressively replaced by structural analogs including bisphenol AF (BPAF) and bisphenol S (BPS) due to growing health concerns. However, the neurobehavioral toxicity… read more here.

DOI: 10.1016/j.neulet.2018.06.042

Abstract: Methamphetamine (Meth) is a psychomotor stimulant associated with increased sexual drive and risky sexual behaviors in both men and women. Females are comparatively understudied, despite the fact that are just as likely as men to… read more here.

DOI: 10.1016/j.neuroscience.2018.03.035

Abstract: The posterodorsal medial amygdala (MePD) is a sex steroid-sensitive and sexually dimorphic subcortical area that dynamically modulates social behaviors in rats. As different microRNA (miRNA) can act as post-transcriptional regulators of synaptic processing, we addressed… read more here.

DOI: 10.1016/j.psyneuen.2021.105249

Abstract: Social experience can generate neural plasticity that changes how individuals respond to stress. Winning aggressive encounters alters how animals respond to future challenges and leads to increased plasma testosterone concentrations and androgen receptor (AR) expression… read more here.

DOI: 10.1038/s41467-024-51652-8

Abstract: The individuals often show consolation to distressed companions or show aggression to the intruders. The circuit mechanisms underlying switching between consolation and aggression remain unclear. In the present study, using male mandarin voles, we identified… read more here.

recommendations! Published in 2022 at "Endocrinology"

DOI: 10.1101/2022.07.07.499104

Abstract: The posterodorsal subnucleus of the medial amygdala (MePD) is an upstream modulator of the hypothalamic-pituitary-gonadal (HPG) and hypothalamic-pituitary-adrenal (HPA) axes. Inhibition of MePD urocortin-3 (Ucn3) neurons prevents psychological stress-induced suppression of LH pulsatility while blocking… read more here.

DOI: 10.1186/s13041-021-00850-2

Abstract: Arginine vasopressin (AVP) is expressed in both hypothalamic and extra-hypothalamic neurons. The expression and role of AVP exhibit remarkable divergence between these two neuronal populations. Polysynaptic pathways enable these neuronal groups to regulate each other.… read more here.

DOI: 10.1523/eneuro.0035-20.2020

Abstract: Abstract The medial amygdala (MeA) is essential for processing innate social and non-social behaviors, such as territorial aggression and mating, which display in a sex-specific manner. While sex differences in cell numbers and neuronal morphology… read more here.

DOI: 10.3389/fendo.2022.893029

Abstract: Post-traumatic stress disorder impedes pubertal development and disrupts pulsatile LH secretion in humans and rodents. The posterodorsal sub-nucleus of the medial amygdala (MePD) is an upstream modulator of the hypothalamic gonadotropin-releasing hormone (GnRH) pulse generator,… read more here.
