In masu salmon (Oncorhynchus masou), coordination of photoperiodic sexual maturation is proposed to involve in a fish-specific circumventricular organ, the saccus vasculosus (SV), through its intrinsic opsin-based light sensitivity, thyrotrophin secretion and modulation of deiodinase activity (TSH-DIO cascade). The saccus vasculosus is a highly vascularized structure located on the ventral side of the hypothalamus and its interface between the blood and cerebrospinal fluid also hints at a role in ionic balance of the cerebrospinal fluid (CSF). Both the potential photoperiodic and ionic functions of the SV led us to perform transcriptome analysis of the SV in smoltification in Atlantic salmon. Specifically, we compared transcriptomes of SVs collected from freshwater fish following exposure to an 8-week stimulated winter photoperiod followed by 8-week simulated summer photoperiod, or a 16-week simulated winter photoperiod control and from both photoperiod treatments after 24 h exposure to seawater. Our data show that SV response to seawater exposure is highly dependent on photoperiodic history and identifies ependymin as a major secretory output of the SV, consistent with a role in control of CSF composition. Conversely, we could not detect crucial elements of the opsin-TSH-DIO cascade suggesting that the photoperiodic history-dependence of the SV to seawater exposure is unlikely to stem from SV-intrinsic responses to photoperiod.","PeriodicalId":54862,"journal":{"name":"Journal of Comparative Physiology A-Neuroethology Sensory Neural and Behavioral Physiology","volume":" ","pages":"69-78"},"PeriodicalIF":2.3,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13038667/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145453940","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 acoustically communicating species, temporal features of calls are critical for distinguishing conspecific from heterospecific signals. Anurans rely heavily on the precise timing of pulse trains for mate recognition. Females of Hyla chrysoscelis use the species-specific temporal structure of male advertisement (Adv) calls-specifically pulse rate (PR)-to select mates. For stimuli with the Adv call PR (40-60 pulses/s), females require at least ~ 6-7 pulses to approach a sound source, implicating interval-counting neurons (ICNs) in call recognition. To test this model and further investigate the neural basis of this temporal selectivity, we used behavioral and neurophysiological approaches. We lengthened interpulse intervals (IPIs) in pulse trains either at a single midpoint or in an alternating fashion while holding pulse number and, thus, stimulus energy constant. In phonotaxis assays, females showed sharply reduced responses when even one IPI was lengthened twofold or more, revealing high sensitivity to temporal irregularity. Single-unit in vivo extracellular recordings from the auditory midbrain revealed that ICNs exhibited a progressive decline in activity with increasing IPI length, closely mirroring behavioral trends. In contrast, long-interval neurons (LINs) responded more strongly to temporally irregular stimuli. These results support the hypothesis that ICNs mediate behavioral selectivity for conspecific Adv call temporal patterns, whereas LINs may contribute to processing other call types. Our study directly links a defined neuronal population to natural behavior, underscoring how midbrain temporal computations underlie species-specific recognition in Hyla chrysoscelis.","PeriodicalId":54862,"journal":{"name":"Journal of Comparative Physiology A-Neuroethology Sensory Neural and Behavioral Physiology","volume":" ","pages":"87-101"},"PeriodicalIF":2.3,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13335587/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145643029","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}

Here, we characterize the phase-shifting effects of brief UVA light flashes in Drosophila ananassae, a species with known sensitivity to short-wavelength light via ocular and extraocular photoreceptors. Using a parametric array of 62 UVA LED protocols varying in flash duration (8, 16, 120 ms), frequency (0.13-1.0 Hz), and irradiance, we quantified circadian phase shifts in the locomotor activity rhythm under constant darkness following stimulation in either the delay (ZT13) or advance (ZT23) zones. Young flies (2-3 days old) exhibited robust phase delays and advances that scaled with flash luminance and frequency. Dose-response modeling revealed increased phase-shifting efficiency and lower energy thresholds with decreasing flash duration, especially at ZT23. By contrast, aged flies (40-45 days) showed significantly attenuated responses, particularly to 8 ms pulses, indicating an age-related decline in UVA sensitivity. These findings suggest that the insect circadian system is finely tuned to the temporal structure of UVA input, with optimal entrainment possibly occurring in response to brief, intermittent stimulation. The marked reduction in responsiveness with age highlights a potential erosion of fast-acting photoreceptive pathways. Given the conservation of UVA-sensitive photopigments across animals, these results offer comparative insights into how temporal light encoding influences circadian regulation across life stages and taxa.","PeriodicalId":54862,"journal":{"name":"Journal of Comparative Physiology A-Neuroethology Sensory Neural and Behavioral Physiology","volume":" ","pages":"551-560"},"PeriodicalIF":2.3,"publicationDate":"2025-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144790773","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}

Humans and animals might well share similar navigational strategies because they developed within the same physical environments. A “map-and-compass” model has been proposed to explain the two-step avian navigational process, but the “map” step has remained elusive. Although scalar values from bicoordinate geomagnetic or atmospheric olfactory gradients have been considered foundational to the avian map, neither has proved convincing engendering decades of controversy. The olfactory map, and an alternative infrasound direction-finding (IDF) hypothesis, are discussed in this review. The olfactory map hypothesis currently requires extensive stable gradients of trace-odor ratios, but such gradients are highly unlikely within a turbulent and rapidly mixed lower atmosphere. The IDF hypothesis, on the other hand, postulates a two-step navigational model analogous to the maritime and aeronautical radio direction-finding technique. This review was also written to encourage further investigation, and direct testing, of the acoustic navigational process. The IDF hypothesis, at present, appears the better explanation of observed avian navigational behavior and accuracy within the atmosphere’s physical environment.","PeriodicalId":54862,"journal":{"name":"Journal of Comparative Physiology A-Neuroethology Sensory Neural and Behavioral Physiology","volume":" ","pages":"603-616"},"PeriodicalIF":2.3,"publicationDate":"2025-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144509500","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}

Here, by investigating in silico the underlying mechanisms, we found that: 1. IK activation rate was the major determinant of both the voltage response narrowing and the impedance gain peaking. Both effects were non-linear, voltage-dependent, with the maxima determined by IK conductance and kinetics. 2. Analysis in the time domain revealed that for efficient modulation, the kinetics of IK must correspond to that of the receptor current: slower-activating IKs more strongly narrowed voltage responses elicited by slower receptor currents than faster-activating IKs, and vice versa. 3. Two complementary mechanisms mediated the modulation: (1) voltage amplification at the onset of receptor current during a window of relatively high resistance due to delayed activation of IK, and (2) attenuation of voltage response during its decay by excessive IK due to its delayed deactivation. Consequently, the action of IK caused a partial leftward shift of voltage waveform relative to the receptor current, resembling the effect of electrical inductance. 4. Voltage response narrowing was opposed by self-shunting of the depolarizing receptor current as it increased. Consequently, the increase in corner frequency due to IK was limited to small voltage responses. Our results elucidate reciprocal relationships between the voltage response and IK, and the conditions when IK can confer band-pass properties to impedance gain function.","PeriodicalId":54862,"journal":{"name":"Journal of Comparative Physiology A-Neuroethology Sensory Neural and Behavioral Physiology","volume":" ","pages":"589-601"},"PeriodicalIF":2.3,"publicationDate":"2025-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145350118","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}
