Here we synthesize the latest research regarding Lepidopteran eye evolution across different timescales, from species-level variation to family-level changes, and mechanistic levels, from broad anatomical variation to molecular mechanisms responsible for spectral tuning. Opsin duplication, differential expression, and co-expression, combined with lateral filtering pigments, generate diverse spectral sensitivities in photoreceptors. Lateral filtering is particularly important for the convergent evolution of red vision. These diverse photoreceptors combine to form a handful of ommatidial types distributed differentially across eye regions, potentially specializing for distinct behavioral tasks. The coordinated development of these complex retinal mosaics requires precise regulatory mechanisms that we are only beginning to understand. Notably, only a subset of these ommatidial types contribute to color vision, highlighting the need for more research on their roles in motion and polarization vision. We also review support cells providing essential functions such as light insulation or reflection. Future research should focus on identifying ecological pressures driving visual system evolution, genetic bases of diverse retinal mosaics, and neural integration of visual information in Lepidoptera.","PeriodicalId":54862,"journal":{"name":"Journal of Comparative Physiology A-Neuroethology Sensory Neural and Behavioral Physiology","volume":" ","pages":""},"PeriodicalIF":2.2,"publicationDate":"2025-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144745998","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite significant advances in mammalian models, studies on reptiles are limited, restricting our understanding of their neurochemical and behavioural interactions. This study aimed to develop and validate a selective liquid chromatography-tandem mass spectrometry (LC-MS/MS) method for the simultaneous quantification of 11 monoamines and their metabolites (adrenaline, dopamine, levodopa, homovanillic acid, 5-hydroxyindoleacetic acid, 5-hydroxytryptophan, serotonin, norepinephrine, tryptophan, tyrosine, vanillylmandelic acid) in lizard brains, examining interspecies and sex-specific variations and their potential link to behavioural differences between Podarcis siculus and Podarcis melisellensis. Brain samples from 132 lizards were analysed using the optimized LC-MS/MS method, which included rigorous pre-analytical preparation to ensure analyte stability. The method demonstrated high sensitivity and specificity for monoamines, with the limit of quantitation lower than 5 ng mL-1. Statistical analyses were performed to assess species, sex, and interaction effects. Significant species differences were observed in tryptophan, 5-hydroxytryptophan and 5-hydroxyindoleacetic acid, with P. siculus males exhibiting the highest levels. No differences were found in the dopamine, noradrenaline or adrenaline pathways. Serotonergic differences align with previously recorded behavioural differences between these two species. This is the first comprehensive study profiling monoamines in lizard brains using LC-MS/MS, providing insights into species-specific neurochemical patterns. The findings underscore the utility of lizards as comparative models in neuroscience and highlight the need for further research into the interplay between neurochemistry and behaviour.","PeriodicalId":54862,"journal":{"name":"Journal of Comparative Physiology A-Neuroethology Sensory Neural and Behavioral Physiology","volume":" ","pages":""},"PeriodicalIF":1.9,"publicationDate":"2025-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144700356","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For example, nerve growth factor (NGF), a key inflammatory mediator, fails to induce sensitization of sensory neurons and thermal hyperalgesia in NMRs. This lack of NGF-induced neuronal sensitization and thermal hyperalgesia results from hypofunctional signaling of the NGF receptor, tropomyosin receptor kinase A (TrkA). Like NGF-TrkA signaling, the neurotrophic factor artemin, a member of the glial cell line-derived neurotrophic factor (GDNF) family, is implicated in mediating inflammatory pain through its receptor, GDNF family receptor α3 (GFRα3), which is expressed by a subset of dorsal root ganglia (DRG) sensory neurons. Here we investigated GFRα3 expression in DRG neurons of mice and NMRs, as well as measuring the impact of artemin on DRG sensory neuron function in both species in vitro. Using immunohistochemistry, we observed a similar abundance of GFRα3 in mouse and NMR DRG sensory neurons, high coexpression with the transient receptor potential vanilloid 1 (TRPV1) ion channel suggesting that these neurons are nociceptive neurons. Using in vitro electrophysiology to record from cultured DRG sensory neurons, we observed that artemin induced depolarization of the resting membrane potential and decreased the rheobase in both species, as well as diminishing the degree of TRPV1 desensitization to multiple capsaicin stimuli. Overall, results indicate that artemin similarly sensitizes sensory neurons in both mice and NMRs, future in vivo studies being required to confirm if the conserved in vitro sensitization also occurs in vivo.","PeriodicalId":54862,"journal":{"name":"Journal of Comparative Physiology A-Neuroethology Sensory Neural and Behavioral Physiology","volume":" ","pages":""},"PeriodicalIF":1.9,"publicationDate":"2025-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144700407","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The solitary foraging of nocturnal bull ants Myrmecia midas in their visually complex environment relies on path integration and landmark learning. While this species seems to be 'sensitive' to handling and reacts to visual changes in their surroundings, not much is known about how added olfactory stimuli impact their route navigation on a vertical surface. In the current study, we added one of five different invisible odours on the trees on which foragers normally forage. We found that the bull ants showed phobic responses to all the odours. The Tea-tree and Lavender odours showed the strongest impact on the bull ants' navigation by causing detours, U-turns, and avoidance of the sensory stimuli, with the ants meandering more and scanning more frequently. The odours of Olive oil, Flax-seed oil, and Eucalyptus oil had a moderate impact on the ants' navigation. These findings showed the widespread influence of non-visual chemical cues in shaping bull ant navigation, reactions that we interpret as neophobic responses stemming from chemical alterations on learned routes. A second experiment supported the interpretation of neophobia as opposed to an inherent aversion to the odours. Repeated exposure to Lavender led to reduced aversive responding. Overall, this study contributes to the understanding of the effects of foreign odours, adding to our understanding of the complex learning processes of bull ants in their vertical navigation.","PeriodicalId":54862,"journal":{"name":"Journal of Comparative Physiology A-Neuroethology Sensory Neural and Behavioral Physiology","volume":" ","pages":""},"PeriodicalIF":1.9,"publicationDate":"2025-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144621145","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, given differential light sensitivity of circadian rhythms during early and late hours of the night, dLAN may have dissimilar detrimental effects in two halves of the night. If so, the disruptive effects of dLAN would be mitigated at different levels if one of the two halves of the night were replaced by complete darkness. We investigated this using both sexes of diurnal zebra finches that were exposed for three weeks to 12 h light (~ 150 lx) coupled with 12 h dark (0 lx), dLAN (5 lx), and half-dark and half-dLAN (6 h dark + 6 h dLAN, or vice versa) nights. dLAN disrupted the nocturnal sleep (shorter sleep bouts, reduced nocturnal sleep with frequent awakenings), and impaired glucose and fat metabolism as evidenced by body fattening and concurrent increase in g6pc, irs1 and star, and decrease in glut5 and sirt1 gene expressions in the liver. The substitution of half of dLAN with complete darkness mitigated much of the negative effects, with a much better alleviative response when the imposed darkness period covered the first half of the 12 h 'dLAN' night. Notably, the mitigation effects of darkness period were sex dependent. These results provide insights into differential temporal sensitivity of the night to negative impacts of the emerging 'light pollution' threat in an over-lit urban environment.","PeriodicalId":54862,"journal":{"name":"Journal of Comparative Physiology A-Neuroethology Sensory Neural and Behavioral Physiology","volume":" ","pages":""},"PeriodicalIF":1.9,"publicationDate":"2025-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144477934","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In my editorial I wish to expose this situation by highlighting the recent disturbing public attack on the scientific integrity of Australian neuroethologist Mandyam Srinivasan, an attack made by scientists outside Srinivasan's field. Srinivasan's integrity was first questioned in a preprint detailing serious allegations of scientific misconduct (that were subsequently shown to be unfounded). This was immediately followed by a concerted press and social media campaign that severely damaged his reputation. The goal of my Editorial is to use these events to encourage our readers to always be cautious in their judgements and to maintain standards of dignity, decency and respect in their treatment of their peers, even if they disagree with them, since this is the way science has always advanced.","PeriodicalId":54862,"journal":{"name":"Journal of Comparative Physiology A-Neuroethology Sensory Neural and Behavioral Physiology","volume":" ","pages":""},"PeriodicalIF":1.9,"publicationDate":"2025-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144295386","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Variation in the ability to detect chemical signals may influence behavior in animals like insects that use volatile cues emitted from plants when discriminating between potential hosts. Differences in odor detection has been demonstrated to play a crucial role in driving changes in host use within and between insect species, leading to reproductive isolation between populations and eventual speciation through specialized host adaptation. We examined between-species variation in odor tuning and asked whether it is linked to shifts in host plant use in the Drosophila repleta species group, a taxonomic radiation of flies specializing on cacti that exhibits multiple shifts in host plant use across their phylogeny resulting in three current states: (1) Opuntia cactus specialists, (2) columnar cactus specialists, and (3) cactus \"generalists\" which use both hosts. We measured odor response profiles from select olfactory sensillar subtypes across multiple species within the group as well as for the outgroup D. melanogaster. Variation in both sensitivity and specificity to odors was observed, with some olfactory sensory neurons exhibiting differences associated with host cactus use. This study is the first in-depth analysis of the olfactory system across the repleta species group and provides the opportunity to test for conserved mechanisms in the olfactory system underlying divergence and host shift.","PeriodicalId":54862,"journal":{"name":"Journal of Comparative Physiology A-Neuroethology Sensory Neural and Behavioral Physiology","volume":" ","pages":""},"PeriodicalIF":1.9,"publicationDate":"2025-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144276746","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
