Topic: passive coping

Major Depressive Disorder (MDD) is characterized by a constellation of symptoms, summarized into three major categories: passive coping strategies, anhedonia, and social impairment.The use of animal models can help to explore these symptoms and investigate their underlying mechanisms, such as oxytocinergic and opioids alterations within the mesocorticolimbic circuit.Exposure to Early Life Adversities (ELA), including Attachment Bond Disruption and Adverse Childhood Experiences, such as Neglect, represents one of the most important risk factors for development of MMD.To model attachment disrupt

The increasing prevalence of psychiatric disorders, such as depression, highlights the need to elucidate their underlying neurobiological mechanisms. The lateral habenula (LHb) and its neuronal activity contribute to the pathophysiology of depression when dysfunctional. Among the existing rodent models of depression, chronic corticosterone administration for 3-4 weeks recapitulates relevant behavioural aspects of the disease such as anhedonia and increased passive coping. However, the temporal emergence of these features and the cellular underpinnings remain unclear. Thus, we assessed the emer
