Exercise intensity matters: A review on evaluating the effects of aerobic exercise intensity on muscle-derived neuroprotective myokines

This review examines how the intensity of aerobic exercise impacts muscle-released factors (myokines) that may protect the brain. It highlights that while regular exercise benefits brain health, the ideal "dose" is unclear, with most research focused on moderate intensity and less on high-intensity. More research is needed, particularly in humans, to directly compare different exercise intensities and their effects on relevant myokine pathways.

The complexity of socially transmitted food preferences in rodents: a model for human epistemic trust?

This commentary argues that the social transmission of food preferences (STFP) in rodents could serve as a model for understanding human epistemic trust, highlighting similarities in behavioral and neural mechanisms influenced by oxytocin. However, it primarily relies on existing rodent studies and speculative links to human behavior without new neurobiological data. The reliance on animal models raises concerns about generalizability to complex human cognition.

The complexity of socially transmitted food preferences in rodents: a model for human epistemic trust?

This commentary explores the social transmission of food preference (STFP) in rodents as a potential model for understanding human epistemic trust. The author argues that the neurobiological mechanisms and behavioral observations in STFP studies, particularly involving oxytocin, may have implications for how humans evaluate and trust information from others, but acknowledges further research is needed to confirm the generalizability to humans.

Oxytocin enhances acquisition in a social trust task in mice, whereas both oxytocin and its antagonist block trust violation learning

This study in mice found that oxytocin enhanced the acquisition of trust-like behavior and, surprisingly, blocked learning from trust violation in male mice, but not females. The researchers used a social transmission of food preference test and modeled trust violation by inducing nausea after social interaction.

The complex neurobiology of resilient functioning after childhood maltreatment

Resilient functioning after childhood maltreatment is a complex process influenced by an interplay of genetic, neurobiological, and social factors. This review highlights the importance of studying resilience as a dynamic system and suggests that future research should focus on longitudinal studies, incorporate advanced statistical techniques, and delve deeper into the underlying mechanisms to develop effective intervention strategies.

Psychometric properties of the perceived stress scale in a community sample of Chinese

The study found that the 10-item and modified 14-item versions of the Perceived Stress Scale (PSS) have satisfactory psychometric properties in a large community sample of Chinese adults. Stress levels measured by the PSS-10 were found to decrease with age and be highest among employed individuals, with no significant gender differences observed.

Vascular and blood-brain barrier-related changes underlie stress responses and resilience in female mice and depression in human tissue

Chronic stress, in mouse models, leads to blood-brain barrier (BBB) alterations in the prefrontal cortex (PFC) of female mice, particularly in those susceptible to stress, marked by a decrease in the tight junction protein Claudin-5 (Cldn5). Similar changes are found in post-mortem brain tissue from women with major depressive disorder (MDD), and disrupting the BBB in female mouse PFC is sufficient to cause anxiety- and depression-like behaviors.
