Open research questions in Neurobiology and Insect Physiology Research

110 unresolved questions extracted from the limitations and future-work sections of 384 Neurobiology and Insect Physiology Research papers in our library. Each links back to the study that raised it.

What the literature leaves open

  • The sample size was limited to three males and three females. The study only examined the morphology and distribution of sensilla on the antennae, mouthparts, legs, and external genitalia of B. melanopus adults.

    Morphology, Distribution and Sexual Dimorphism of Sensilla in the Tea Leaf Beetle Basilepta melanopus (Coleoptera: Eumolpidae) · 2026 · DOI

  • Further studies could investigate the functional significance of the different types of sensilla. The relationship between sensilla and behavioral activities could be explored in more detail.

  • Odors allow animals to evaluate resources and risks, but the neural and inherited consequences of experience with ecologically meaningful odors remain poorly understood.

  • Visual motion processing in flying insects is strongly modulated by behavioural state, yet the mechanisms by which mechanosensory feedback contributes to this modulation remain poorly understood.

    Wing mechanosensory modulation of optic flow-sensitive descending neurons in butterflies · 2026 · DOI

  • Neuropeptides regulate diverse and sometimes opposing functions, yet how a single peptide achieves functional specificity remains unclear.

  • Acetylcholine (ACh) is an ancient, highly conserved neurotransmitter, yet the functional diversification of cholinergic pathways across early chordates remains incompletely understood.

    Anatomical and functional organisation of the cholinergic nervous system in the tunicate Botryllus schlosseri · 2026 · DOI

  • While optic flow-based biologically plausible models for the honeybee visual odometer were previously presented, their robustness with respect to uneven terrain has not yet been investigated.

    Leveling the head relative to ground slope improves visual odometry in simulated bees · 2026 · DOI

  • Yet, sex pheromone compositions of many species remain poorly characterized outside important agricultural pests, because of the necessity to access live insects for pheromone extraction, the difficulties in identifying the production period, and the precise identification of behaviorally relevant compounds in extracts.

    Odorant receptor structures predict the major female sex pheromone component in a moth · 2026 · DOI

  • However, the temporal dynamics of how bees form associations between visual cues and collision experiences remain unclear.

    Bees exhibit behavioural flexibility to learned visual cues to prevent negative consequences during navigation in clutter · 2026 · DOI

  • Although octopamine (OA) is a key regulator of insect stress physiology, including thermal stress, the receptor‐specific mechanisms by which individual octopamine receptors coordinate thermal tolerance, survival, and life‐history traits remain poorly understood.

    Octopamine Signaling Mediates Thermal Stress Adaptation in Drosophila melanogaster · 2026 · DOI

  • Yet the neural circuits that transform taste into motivationally relevant signals remain poorly defined in any model system.

  • Male same-sex sexual behavior (SSB) is widespread among animal species, but its proximate (mechanistic) and ultimate (evolutionary) explanations remain unclear.

    Evolutionary basis of male same-sex sexual behavior by multiple pheromone switches in Drosophila · 2026 · DOI

  • The relation between regional morphological features derived from the bilaterian body plan and the behaviours necessary to extract utility from such structures is not well understood.

    Region-specific mechanosensation modulates Drosophila postural control behaviour · 2026 · DOI

  • Because Orco expression is sparse in legs, this sensory compensation requires an indirect, long-range mechanism.

    Cross-modal sensory compensation increases mosquito attraction to humans · 2025 · DOI

  • However, the molecular link between photoperiod and hormonal control remains poorly understood.

    The PBAP chromatin remodeling complex mediates summer diapause via H3K4me3-driven juvenile hormone regulation in Colaphellus bowringi · 2025 · DOI

  • Although its existence in cells and tissues across many biological kingdoms is well documented, how and why it forms remains elusive and uncovering these formation mechanisms will undoubtedly inform bioinspired designs.

    Hierarchical woven fibrillar structures in developing single gyroids in butterflies · 2025 · DOI

  • However, the stoichiometric ratios of the heterotetramers remain inconclusive, and the molecular mechanism by which the ligand initiates channel opening is still not fully understood.

    Probing the optimal architecture and molecular mechanism of insect odorant receptor heteromeric channels · 2025 · DOI

  • However, the transcriptional regulation mechanism that causes this expression alteration of OBPs still remains unclear.
