This paper describes the receptive fields of phase-locked neurons in the midbrain of A. albifrons, in combination with neuroanatomy and electron microscopy (EM) to delineate a phase-locked area in this fish, the magnocellular mesencephalic nucleus (MMN). The MMN was isolated electrophysiologically through the detection of phase-locked field potentials of high amplitude. Single-cell recordings were made with a sharp electrode while a phase-locked modulated stimulus was provided to the fish. Receptive field centers of phase-locked neurons in MMN were consistent with tuberous electroreceptor density maps from previous studies, but no receptive field centers were found in the posterior 50% of the body. Intracellular and extracellular labeling of MMN revealed three cell populations: giant cells with large somata (19-24 µm) and their axonal arborizations which span across the entire extent of MMN, axon terminals from spherical cells of the electrosensory lateral line lobe (ELL), and small cell somata (3-7 µm) along with their projections which extend outside the nucleus. EM revealed multiple gap junction and chemical synapses within MMN. Our results indicate that MMN is a dedicated temporal processing center in A. albifrons.","PeriodicalId":15397,"journal":{"name":"Journal of Comparative Physiology A","volume":"31 1","pages":"405-420"},"PeriodicalIF":0.0,"publicationDate":"2022-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81044073","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We developed a whole-animal behavioral assay that takes advantage of octopuses' natural searching behavior to test their ability to discriminate prey from non-prey tastes solely via contact chemoreception. This methodology eliminated vision, mechano-tactile sensing and distance chemoreception while testing the contact chemosensory discriminatory abilities of the octopus arm suckers. Extracts from two types of prey (crab, shrimp) and three types of non-prey (sea star, algae, seawater) were embedded in agarose (to control for mechano-tactile discrimination) and presented to octopuses inside an artificial rock dome; octopuses reached their arms inside to explore its contents - imitating natural prey-searching behavior. Results revealed that octopuses are capable of discriminating between potential prey items using only contact chemoreception, as measured by an increased amount of sucker contact time and arm curls when presented with prey extracts versus non-prey extracts. These results highlight the importance of contact chemoreception in the multi-modal sensing involved in a complex foraging behavior.","PeriodicalId":15397,"journal":{"name":"Journal of Comparative Physiology A","volume":"8 1","pages":"435-442"},"PeriodicalIF":0.0,"publicationDate":"2022-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76282545","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, quantitative research on gecko's kinematic performance and the effect of obstacle height during transitional locomotion remains scarce. In this study, the transitional locomotion of geckos facing different obstacle heights was assessed. Remarkably, geckos demonstrated a bimodal locomotion ability, as they could climb and jump. Climbing was more common on smaller obstacles and took longer than jumping. The jumping type depended on the obstacle height: when geckos could jump onto the obstacle, the vertical velocity increased with obstacle height; however, geckos jumped from a closer position when the obstacle height exceeded this range and would get attached to the vertical surface. A stability analysis of vertical surface landing using a collision model revealed that geckos can reduce their restraint impulse by increasing the landing angle through limb extension close to the body, consequently dissipating collision energy and reducing their horizontal and vertical velocities. The findings of this study reveal the adaptations evolved by geckos to move in their environments and may have applicability in the robotics field.","PeriodicalId":15397,"journal":{"name":"Journal of Comparative Physiology A","volume":"1 1","pages":"421-433"},"PeriodicalIF":0.0,"publicationDate":"2022-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82998286","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Decisions for behavioral plasticity are achieved through the neuromodulation of sensory processes, including motion vision. Here, we briefly review the anatomy of the insect motion vision system. Next, we review the neuromodulatory influences on motion vision. Serotonin modulates peripheral visual processing, whereas octopamine modulates all stages of visual processing tested to date. The physiological and behavioral states that elicit neuromodulation of motion vision include locomotion, changes in internal physiological state such as hunger, and changes in the external environment such as the presence of additional sensory cues. The direction of influence between these states and neuromodulators remains unknown. The influence of neuromodulators on motion vision circuitry has been revealed mostly through pharmacological application, which broadcasts widely with unnatural spatiotemporal dynamics. Thus, insight from this method is limited. Aminergic neurons likely act in local hierarchical fashion rather than globally as a group. As genetic tools advance in Drosophila, future work restricting the experimental focus to subpopulations of modulatory neurons will provide insight into the local functional modifications of visual circuits by interacting neuromodulators.","PeriodicalId":15397,"journal":{"name":"Journal of Comparative Physiology A","volume":"29 1","pages":"125-137"},"PeriodicalIF":0.0,"publicationDate":"2020-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76036761","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although downstream elements have been described both anatomically and physiologically throughout the optic lobes and the central brain of different species, little is known about their cellular and synaptic adaptations and how these shape their functional role in polarization vision. We have previously shown that in the DRA of Drosophila melanogaster, two distinct types of modality-specific 'distal medulla' cell types (Dm-DRA1 and Dm-DRA2) are post-synaptic to long visual fiber photoreceptors R7 and R8, respectively. Here we describe additional neuronal elements in the medulla neuropil that manifest modality-specific differences in the DRA region, including DRA-specific neuronal morphology, as well as differences in the structure of pre- or post-synaptic membranes. Furthermore, we show that certain cell types (medulla tangential cells and octopaminergic neuromodulatory cells) specifically avoid contacts with polarization-sensitive photoreceptors. Finally, while certain transmedullary cells are specifically absent from DRA medulla columns, other subtypes show specific wiring differences while still connecting the DRA to the lobula complex, as has previously been described in larger insects. This hints towards a complex circuit architecture with more than one pathway connecting polarization-sensitive DRA photoreceptors with the central brain.","PeriodicalId":15397,"journal":{"name":"Journal of Comparative Physiology A","volume":"39 1","pages":"233-246"},"PeriodicalIF":0.0,"publicationDate":"2020-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78799483","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The organization of stomatopod retinas is well established, but their optic lobes have been studied less. We used histological staining, immunolabeling, and fluorescent tracer injections to compare optic lobes in two 6-row midband species, Neogonodactylus oerstedii and Pseudosquilla ciliata, to those in two 2-row midband species, Squilla empusa and Alima pacifica. Compared to the 6-row species, we found structural differences in all optic neuropils in both 2-row species. Photoreceptor axons from 2-row midband ommatidia supply two sets of lamina cartridges; however, conspicuous spaces lacking lamina cartridges are observed in locations corresponding to where the cartridges of the upper four ommatidial rows of 6-row species would exist. The tripartite arrangement and enlarged projections containing fibers associated with the two rows of midband ommatidia can be traced throughout the entire optic lobe. However, 2-row species lack some features of medullar and lobular neuropils in 6-row species. Our results support the hypothesis that 2-row midband species are derived from a 6-row ancestor, and suggest specializations in the medulla and lobula found solely in 6-row species are important for color and polarization analysis.","PeriodicalId":15397,"journal":{"name":"Journal of Comparative Physiology A","volume":"16 1","pages":"247-258"},"PeriodicalIF":0.0,"publicationDate":"2020-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84306045","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study was undertaken to investigate the bulk flow of cerebrospinal fluid, and the resulting changes in intracranial pressure, in a common reptilian species. Intracranial pressure was measured using ocular ultrasonography and by surgically implanting pressure cannulae into the cranial subarachnoid space. The system was then challenged by: rotating the animal to create orthostatic gradients, perturbation of the vascular system, administration of epinephrine, and cephalic cutaneous heating. Pressure changes determined from the implanted catheters and through quantification of the optic nerve sheath were highly correlated and showed a significant linear relationship with orthostatic gradients. The catheter pressure responses were phasic, with an initial rapid response followed by a much slower response; each phase accounted for roughly half of the total pressure change. No significant relationship was found between intracranial pressure and either heart rate or blood flow. The focal application of heat and the administration of epinephrine both increased intracranial pressure, the latter influence being particularly pronounced.","PeriodicalId":15397,"journal":{"name":"Journal of Comparative Physiology A","volume":"23 1","pages":"45-54"},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82530571","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
