The histone code for that cell type starts the regulatory cascade that turns on the genes associated with that particular type of cell, transforming it from a multipotent cell to a fully differentiated cell. This mechanism creates structures in the musculoskeletal system, the organs of the body, the major parts of the brain, and other systems. Living in the past, the present, or the future can affect stress and health. Our group has shown that acute stress (cortisol reactivity) is modulated by time perspectives, the ways we psychologically relate to time. Here, we expand this research with a comprehensive measure of multi-systemic chronic stress (allostatic load). Among 204 healthy adults (60 men; 144 women), we examined whether time perspectives modulate allostatic load measured with 23 neuroendocrine, immune, metabolic, and cardiovascular biomarkers. Five time perspective categories were measured (past negative, past positive, present hedonistic, present fatalistic, future). Multiple regressions controlling for sex, age, and depressive symptoms were used. Increased present fatalistic time perspective was positively correlated with allostatic load, while future time perspective was negatively correlated with allostatic load. Our preliminary findings link time perspective to multisystemic chronic stress and are discussed in the context of potential clinical implications. V.A hallmark of the prefrontal cortex (PFC) is flexible representation of task-relevant variables. To investigate roles of different interneuron subtypes in this process, we examined discharge characteristics and inactivation effects of parvalbumin (PV)- and somatostatin (SST)-expressing neurons in the mouse PFC during probabilistic classical conditioning. We found activity patterns and inactivation effects differed between PV and SST neurons SST neurons conveyed cue-associa
