This study identifies the BAC as a PACAPergic hub linking emotional and spatial networks in looming-threat learning and memory using a novel behavioral paradigm and chemogenetic approaches.

This study shows that neonatal maternal separation primes adrenal chromaffin cells to have heightened stress-induced connexin remodeling in adulthood.

The paper identifies a KF PACAP/VGluT1 pathway to the extended amygdala that mediates rapid autonomic compensation during acute hypotension, preceding slower endocrine responses.

The paper identifies a multimodal calyx-like synapse in the forebrain extended amygdala formed by glutamatergic afferents from the pontine Kolliker-Fuse nucleus that co-release multiple neurotransmitters and neuropeptides.

The paper maps kisspeptin (KP) fiber distribution and Kiss1r expression in rat and mouse brains, showing their involvement in sensorial processing and behavioral state control beyond reproductive functions.

The paper identifies seven distinct kisspeptin neuronal chemotypes in the mouse brain and shows gonadectomy alters their expression patterns.

The paper reports morphological evidence of low-rate neurogenesis and migration in the adult rat AVPMNS using immunohistochemical markers.

The paper identifies a neural circuit involving the NLOT that links the SON-AVP system to neocortical regions, promoting social behavior under osmotic stress.

The paper shows that vasopressin increases PSD95 and GluA1 expression in limbic regions, enhancing synaptic strength, while having no effect in non-target regions.

The paper examines ACE2 expression in rat brain tissues, identifying its presence in astrocytes, pericytes, endothelial cells, and specific neuronal populations, suggesting potential neurological impacts of SARS-CoV-2 infection.

This study shows that early life stress alters microglial synaptic pruning of axon initial segments in rats, with stronger effects in females, leading to increased fear responses in adulthood.

The paper investigates the role of PACAP signaling in neuronal subpopulations by analyzing its distribution and effects on behavior and gene expression in mice.
