DOI: 10.1002/hbm.26104
Abstract: The neuroanatomical circuitry of jaw muscles has been mostly explored in non‐human animals. A recent rodent study revealed a novel circuit from the central amygdala (CeA) to the trigeminal motor nucleus (5M), which controls biting… read more here.

Distinct circuits in rat central amygdala for defensive behaviors evoked by socially signaled imminent versus remote danger
Sign Up to like & getrecommendations! Published in 2021 at "Current Biology"
DOI: 10.1016/j.cub.2021.03.047
Abstract: Animals display a rich repertoire of defensive responses adequate to the threat proximity. In social species, these reactions can be additionally influenced by the behavior of fearful conspecifics. However, the majority of neuroscientific studies on… read more here.

DOI: 10.1016/j.expneurol.2021.113744
Abstract: The dysregulation of neuronal networks may contribute to the etiology of major depressive disorder (MDD). However, the neural connections underlying the symptoms of MDD have yet to be elucidated. Here, we observed that glutamatergic neurons… read more here.

DOI: 10.1038/nn.4639
Abstract: Central amygdala directs behavioral responses to emotionally salient stimuli. While most studies have focused on aversive responses, some central amygdala neurons promote feeding and are positively reinforcing. read more here.

DOI: 10.1038/s41380-019-0599-6
Abstract: Norepinephrine (NE) plays a central role in the acquisition of aversive learning via actions in the lateral nucleus of the amygdala (LA) [ 1 , 2 ]. However, the function of NE in expression of… 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.

DOI: 10.1093/tas/txy075
Abstract: Reindeer bulls are difficult to manage and dangerous to handlers during the rutting period. Progesterone agonists have been used anecdotally in the field to favorably influence behavior, but effects on reproductive signaling have not been… read more here.

DOI: 10.1111/adb.12813
Abstract: Administration of selective serotonin reuptake inhibitors (SSRIs), typically used as antidepressants, induces long-lasting behavioral changes associated with alcohol use disorder (AUD). However, the contribution of SSRI (fluoxetine)-induced alterations in neurobiological processes underlying alcohol relapse such… read more here.

DOI: 10.3389/fnbeh.2022.879168
Abstract: Three studies provide evidence that the central nucleus of the amygdala, a structure with a well-established role in conditioned freezing, is also required for conditioned facilitation of instrumental avoidance in rats. First, the immediate early… read more here.

DOI: 10.3389/fnins.2023.1178693
Abstract: Mammals are frequently exposed to various environmental stimuli, and to determine whether to approach or avoid these stimuli, the brain must assign emotional valence to them. Therefore, it is crucial to investigate the neural circuitry… read more here.
