Many animal studies have explored decision-making under risk and punishment, particularly regarding potential rewards, but less focus has been placed on contexts involving net losses. Understanding decision-making under net loss conditions can shed light on the neural mechanisms involved. The basolateral amygdala to prelimbic cortex (BLA→PL) pathway is crucial for risky decision-making.

Unlabelled: Focal adhesions and their dynamic nature are essential for various physiological processes, including the formation of neurites, synaptic function and plasticity. Alterations in these processes have been associated with schizophrenia and bipolar disorder.
Objectives: This study aimed to explore the impact of pharmacological treatments used for bipolar disorder and schizophrenia on the expression of genes involved in the focal adhesion pathway, addressing a gap in understanding the interaction between medication effects and disease pathophysiology.
Inhibition of prefrontal glutamatergic neuron activity during the recovery period following chronic stress disrupts fear memory in male rats: potential role of the infralimbic cortex.

Chronic stress typically leads to deficits in fear extinction. However, when a delay occurs from the end of chronic stress and the start of fear conditioning (a "recovery"), rats show improved context-cue discrimination, compared to recently stressed rats or nonstressed rats. The infralimbic cortex (IL) is important for fear extinction and undergoes neuronal remodeling after chronic stress ends, which could drive improved context-cue discrimination.

Schizophrenia is a chronic psychiatric disorder with a complex etiology involving genetic, neurobiological, and environmental factors. Many individuals with schizophrenia experience treatment resistance despite advances in pharmacologic and non-pharmacologic interventions. Immune dysregulation, characterized by altered cytokine levels, immune-related gene expression, and neuroinflammation, plays a critical role in schizophrenia's pathogenesis.
