It also acts as an agonist on acetylcholine receptors in the insect central nervous system, but its neurophysiological effects on individual interneurons are poorly understood. Here, we investigated the effects of sublethal flupyradifurone intoxication on the neural processing of auditory information in the field cricket Gryllus bimaculatus. Using a suction electrode on the brain surface, we recorded the spiking activity of the two ascending auditory interneurons AN1 and AN2 while injecting the insecticide into the prothorax. Flupyradifurone caused a dose-dependent decrease in sound-evoked spike responses and an increase in spontaneous spiking activity in both ascending auditory interneurons, eventually leading up to a collapse of all spiking activity the highest dose tested (20 µl of 10- 3 mol/l). The substantial increase of spontaneous spiking activity in AN1 and AN2, which started with 20 µl of 10- 5 mol/l flupyradifurone treatment, will mask the neuronal coding of relevant acoustic signals required for auditory feature detection in the higher brain circuits. Field crickets rely on AN1 to transmit low-frequency auditory information for pattern recognition in phonotactic mate finding, and on AN2 to transmit high-frequency auditory information for sound source localization in predator avoidance behaviour. The disruption of auditory processing at the level of ascending interneurons by this insecticide will negatively impact the chances for reproduction and survival in crickets.","PeriodicalId":54862,"journal":{"name":"Journal of Comparative Physiology A-Neuroethology Sensory Neural and Behavioral Physiology","volume":" ","pages":"617-632"},"PeriodicalIF":2.3,"publicationDate":"2026-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13396037/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147870433","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Meta II initiates the phototransduction cascade, culminating in membrane hyperpolarization. To investigate how meta II lifetime shapes the rod photoresponse, we studied a knock-in mouse expressing E122Q rhodopsin, a mutant pigment with a shortened meta II lifetime. Microspectrophotometry confirmed that E122Q rhodopsin is blue-shifted in its absorbance spectrum and exhibits significantly faster meta II decay than wild-type (WT). Patch-clamp recordings revealed that this shortened lifetime had little effect on response kinetics or on the dominant time constant of recovery after bright flashes. However, following pigment bleaching, rods expressing E122Q showed markedly greater desensitization than WT, indicating that free E122Q opsin activates the phototransduction cascade more efficiently in darkness. To our knowledge, this is the first report of a rhodopsin mutation that alters free opsin-driven activation of phototransduction. Given that many disease-causing mutations affect dark adaptation, such opsin-based mechanisms may be more common than previously appreciated.","PeriodicalId":54862,"journal":{"name":"Journal of Comparative Physiology A-Neuroethology Sensory Neural and Behavioral Physiology","volume":" ","pages":""},"PeriodicalIF":2.3,"publicationDate":"2026-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148340982","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 difference in refractive index of chitin and melanin results in refractive index profiles, the dimensions of which determine the local reflectance spectra and thus the beetles' colour pattern. Building on the exemplary case of the jewel beetle Chrysochroa fulgidissima, the refractive index profiles of several buprestid species were derived from transmission electron micrographs. The profiles were implemented in a matrix transfer model that allowed calculation of the multilayers' reflectance spectra, which were compared with measured spectra. The elytral surface of jewel beetles varies from smooth to highly sculpted. With a smooth surface, the elytra act as specular reflectors, but undulating surfaces cause spatially broadened reflections, resulting in a matte appearance, as is particularly the case in Chysochroa gratiosa, an extreme example of elytra with strongly sculpted, multilayered elytra.","PeriodicalId":54862,"journal":{"name":"Journal of Comparative Physiology A-Neuroethology Sensory Neural and Behavioral Physiology","volume":" ","pages":""},"PeriodicalIF":2.3,"publicationDate":"2026-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148340952","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}

While the challenges faced by signalers in urban environments are increasingly understood, far less is known about how urbanization influences the physiology or behavior of sensory receivers. Here, we examined the relationship between urbanization and auditory sensitivity of house sparrows (Passer domesticus), a human-commensal songbird that inhabits environments spanning a rural–urban gradient. We used auditory brainstem responses (ABRs) to assess hearing sensitivity across individuals captured at sites differing in urbanization. We predicted that urban-living would be associated with frequency-dependent changes in auditory sensitivity. In particular, we expected that urban sparrows may have greater high-frequency sensitivity compared to their rural counterparts, consistent with reported shifts in urban song structure. Overall, our results showed mixed support for this prediction. Increased levels of urbanization were associated with lower hearing sensitivity and greater delays in the ABR but the exact magnitude and direction of these effects depended on how urbanization was quantified, the sex of the individual, and the features of the acoustic stimulus. These changes in auditory processing with urbanization may reflect a communication cost to sensory receivers or, alternatively, a mechanism for avoiding noise masking. These findings are some of the first evidence in songbirds that the sensory physiology of receivers, not just signalers, can be impacted by human activity.","PeriodicalId":54862,"journal":{"name":"Journal of Comparative Physiology A-Neuroethology Sensory Neural and Behavioral Physiology","volume":" ","pages":"555-578"},"PeriodicalIF":2.3,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147516574","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 such contact zones, male advertisement calls and corresponding female preferences can diverge between sympatric and allopatric populations, contributing to reproductive isolation. The neural basis of these population-level differences in communication, however, remains poorly understood. In the Upland chorus frog (Pseudacris feriarum), sympatric populations produce advertisement calls with faster pulse rates and/or more pulses per call than allopatric populations. To examine potential neural correlates of this divergence, we recorded from long-interval neurons (LINs) in the auditory midbrain using in vivo extracellular methods and compared their temporal selectivity across populations. LINs from allopatric populations responded to a wider range of pulse rates, extending to faster rates than LINs from sympatric populations, which responded primarily to slower pulse rates characteristic of heterospecific calls. These findings demonstrate population-level differences in LIN temporal tuning and reveal a mismatch between pulse rate selectivity and the temporal properties of sympatric advertisement calls. Our results reveal that LINs are a target of reinforcing selection, and provide initial evidence toward understanding how auditory processing differs across populations experiencing different selective pressures.","PeriodicalId":54862,"journal":{"name":"Journal of Comparative Physiology A-Neuroethology Sensory Neural and Behavioral Physiology","volume":" ","pages":"473-482"},"PeriodicalIF":2.3,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145851406","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}

Cataglyphis ants are experimental models for insect navigation and magnetoreception. At the beginning of their foraging life, Cataglyphis ants perform learning walks (LWs), explorative excursions around the nest, with pirouettes (tight turns about the ants' body axes). During a pirouette, an ant gazes to the nest entrance, an invisible hole in the ground. Until now, Cataglyphis nodus has been the only desert ant species shown to use the GMF to align their gazes to the nest entrance during LW pirouettes. In the present study, we show that Cataglyphis hellenica, phylogenetically distant from C. nodus, but inhabiting the same environment, also possesses a magnetic sense. When C. hellenica ants are exposed to an experimental alteration of the GMF (alteration of the horizontal component about 180° or + 120°), they gaze to the fictive position of the nest entrance. This study demonstrates that C. hellenica ants use the GMF to gaze back to the nest entrance, confirming the presence of magnetoreception in a second Cataglyphis species, in addition to C. nodus. This suggests that the use of the GMF for path integration is rather common than unique in Cataglyphis species.","PeriodicalId":54862,"journal":{"name":"Journal of Comparative Physiology A-Neuroethology Sensory Neural and Behavioral Physiology","volume":" ","pages":"517-526"},"PeriodicalIF":2.3,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13198454/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146127652","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In an earlier study of coho salmon (Oncorhynchus kisutch), we observed that elevated CO2 exposure impaired signaling in the olfactory bulb, through a mechanism likely involving interference of gamma-aminobutyric acid (GABA) signaling. However, the effects of elevated CO2 may be species-specific, and there have been few studies addressing the effects of elevated CO2 on benthic fish. In the current study, we investigated the effects of elevated CO2 exposures on the deep-water benthic species, sablefish (Anoplopoma fimbria). Sablefish were exposed to three different levels of CO2 (700, 1600 and 2700 µatm) for two weeks, followed by behavioral, neurophysiological and gene expression analysis of the olfactory system. Analysis of behaviors mediated by food odors, including swimming activity and food strikes did not differ between fish maintained under elevated or control CO2 conditions. Similarly, electro-olfactogram recordings of odorant signaling did not differ among treatment and controls. mRNA expression patterns of olfactory bulb genes that were altered in coho salmon exposed to elevated CO2 levels, were similarly examined in sablefish. Sablefish mRNAs encoding genes involved in GABA-mediated olfactory bulb signaling were generally unaffected by high CO2, but aldh9a1, an enzyme involved in the synthesis of GABA, was elevated by high CO2. The results of our study contrast other studies demonstrating adverse effects of elevated CO2 in pelagic fish, but support differences among fish species to susceptibility to elevated CO2, potentially associated with life history traits.","PeriodicalId":54862,"journal":{"name":"Journal of Comparative Physiology A-Neuroethology Sensory Neural and Behavioral Physiology","volume":" ","pages":"527-539"},"PeriodicalIF":2.3,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147470248","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}
