Open research questions in Neuroendocrine regulation and behavior

349 unresolved questions extracted from the limitations and future-work sections of 1,224 Neuroendocrine regulation and behavior papers in our library. Each links back to the study that raised it.

What the literature leaves open

  • The study faced challenges in controlling for potential confounding effects, such as individual differences in mood states and personality traits. The study also faced challenges in interpreting the results, particularly with regards to the temporal-dependent effects of oxytocin on attentional processing. Additionally, the study had to overcome the challenge of balancing the need for a large sample size with the need for a controlled and standardized experimental design.

  • The study only included healthy male participants, - The sample size was limited to 60 participants, - The study did not control for all potential confounding effects

  • Investigate modality- and sex-dependent mechanisms of social buffering of social fear, - Consider sex as a biological variable in the study of social buffering, - Elucidate the mechanisms underlying sex-related differences in physiological responses to social stress

  • Longitudinal studies to investigate the long-term effects of oxytocin administration - Transdiagnostic investigations to clarify the therapeutic and mechanistic significance of oxytocin-sensitive white matter functional organization - Studies to investigate the effects of oxytocin administration on other psychiatric disorders

  • The therapeutic potential of oxytocin for depression, particularly through white matter circuit modulation, remains poorly understood. The spatial pattern of WM dysfunction observed in psychiatric disorders has been associated with the distribution of disease-related neurotransmitters and the expression maps of specific genes.

  • the study did not observe correlations between childhood adversity exposure and OXT plasma levels, - the results are in contrast to those of Mielke et al. (2023) reporting an association between plasma OXT and adverse childhood experiences, - the study had a limited sample size

    Reduction of oxytocin plasma levels in borderline personality disorder and normalization induced by psychotherapies · 2025 · DOI

  • further studies are needed to investigate the role of OXT in attachment, - research should be conducted to examine the effects of exogenously administered OXT on attachment insecurity, - studies should be done to explore the relationship between childhood adversity exposure and OXT plasma levels

  • Further research is needed to disentangle shared trajectories linking social behaviour with later-life and mental health outcomes, - Investigating the biological mechanisms underlying social development is necessary, - More studies are required to understand the genetic architecture of social behaviour

    Genome-wide analysis of social behaviour across social domains, reporters and developmental stages: a meta-regression approach · 2026 · DOI

  • Innate preferences determine how animals interact with the environment, but how experience refines the neural processes underlying those intrinsic motivations is not well understood.

  • The genetic architecture of social behaviour is not well understood. Prior studies have not fully accounted for the variation in social behaviour across different social contexts. There is a need for a comprehensive analysis of the genetic correlates of social behaviour.

  • Despite their well-recognized role in homeostatic maintenance, mechanisms by which sensory CVOs detect and translate homeostatic and immune fluctuations into behavioral responses are not well understood.

    Neuroimmune regulation of behavior: Focus on sensory circumventricular organs and associated cell circuit mechanisms · 2026 · DOI

  • The anterior cingulate cortex (ACC) has been repeatedly implicated in social rejection and social distress, but the circuit-level organization through which ACC may contribute to social motivational responses remains unclear.

  • BACKGROUND: Kidney disease is a common and clinically significant problem in dogs and cats, yet the underlying pathophysiological mechanisms remain incompletely understood.

  • Although prior studies have explored the learning and neural representation of own rank, 5 , 10 , 11 how opponent rank is detected and encoded remains unclear.

  • Pleasant touch sensations play a fundamental role in social bonding, yet the neural mechanisms underlying affinity-like behaviors remain poorly understood.

    Oxytocin facilitates human touch-induced play behavior in rats · 2025 · DOI

  • Although multifunctional circuits offer an efficient solution for behavioral flexibility and may drive rapid evolutionary adaptations, their neural mechanisms remain poorly understood, especially in mammals.
