Pain associates both sensory and emotional aversive components, often leads to anxiety depression when it becomes chronic. Here, we characterized, in a mouse model, the long-term development of these components as well anxiodepressive-like consequences neuropathic pain determined their electrophysiological impact on anterior cingulate cortex (ACC, cortical areas 24a/24b). We show that symptoms evolve recover different time courses following nerve injury male mice. In vivo recordings evidence...
Abstract While depression and chronic pain are frequently comorbid, underlying neuronal circuits their psychopathological relevance remain poorly defined. Here we show in mice that hyperactivity of the pathway linking basolateral amygdala to anterior cingulate cortex is essential for pain-induced depression. Moreover, activation this naive male mice, absence on-going pain, sufficient trigger depressive-like behaviors, as well transcriptomic alterations recapitulate core molecular features...
A new cricket of the genus Scapsipedus is described from Kenya. The distribution, acoustic behavior, including call and courtship song, mitochondrial sequences, data on biology that species are given. This edible a very promising for mass production food feed.
Most high volcanic islands of Lesser Antilles harbor one single genus Anostostomatidae: Rhumosa n. gen: bolognei gen. sp. in Guadeloupe, macoucheriei Dominica, depazei Martinique, admiralrodneyei Saint Lucia, captainblighei sp., Vincent. These species are restricted to well preserved rainforests; from northern apparently occurring at higher elevation than southern islands. The distribution and generic position is discussed, as the Lutosa cubaensis (Haan, 1843).
The occurrence of Nemobiinae crickets (Grylloidea, Trigonidiidae) in the Lesser Antilles is attested here for first time, by descriptions three new species Absonemobius Desutter-Grandcolas, 1993 from Guadeloupe, St. Lucia and Vincent: septentrion n. sp., lucensis sp. vincenti discovery Hygronemobius Hebard, 1913 Guadeloupe. generic attribution several nemobiine described Caribbean Southern Central America are also reviewed: Nemobius elegans Otte, 2006 Costa Rica Pteronemobius sanaco Otte...
Shield-backed katydids of tribe Arytropteridini Caudell, 1908 are recorded for the first time in Madagascar. The new genus Toliaridectes n. gen. is proposed to include three species from south west island: meridionalis sp., wendenbaumi sp. and antsycurvis sp.. Elements biology given call described. taxonomic position discussed.
Two species of Eucocconotini Beier, 1960 were collected during the "Our Planet Revisited, Mitaraka 2015" survey in Mountains belonging to Tumuc-Humac mountain chain French Guiana: Gnathoclita vorax (Stoll, 1813) and Panoploscelis scudderi 1950. Calling songs both are described for first time, as well mandibular tegminal protest signals from P. males females. The structures involved these illustrated. peculiar acoustic mate guarding behaviors synonymy scudderiBeier, 1950 angusticauda Beier n....
The superficial layers of the spinal cord dorsal horn (DH) express P2X2, P2X4, and P2X6 subunits entering into formation ionotropic (P2X) receptors for ATP. Using a culture system laminae I-III from neonatal rat DH, we show that ATP induced fast nonselective cation current in 38% neurons (postsynaptic effect). also increased frequency miniature IPSCs (mIPSCs) mediated by GABA(A) or glycine 22 9%, respectively, tested (presynaptic effect) but had no effect on glutamatergic transmission....
Synaptic plasticity at neuronal connections has been well characterized functionally by using electrophysiological approaches, but the structural basis for this phenomenon remains controversial. We have studied dynamic interactions between presynaptic and postsynaptic structures labeled with FM 4-64 a membrane-targeted GFP, respectively, in hippocampal slices. Under conditions of reduced activity (1 μM tetrodotoxin), we observed extension glutamate receptor-dependent processes from dendritic...
Pollinator-mediated selection and evolution of floral traits have long fascinated evolutionary ecologists. No other plant family shows as wide a range pollinator-linked forms Orchidaceae. In spite the large size this model history orchid pollination biology, identity specificity most pollinators remains inadequately studied, especially in tropics where has undergone extensive diversification. Angraecum (Vandeae, Epidendroideae), genus tropical Old World orchids renowned for their morphology...
Orthoptera have been used for decades numerous evolutionary questions but several of its constituent groups, notably crickets, still suffer from a lack robust phylogenetic hypothesis. We propose the first hypothesis evolution crickets sensu lato, based on analysis 205 species, representing 88% subfamilies and 71% tribes currently listed in database Species File (OSF). reconstructed parsimony, maximum likelihood Bayesian phylogenies using fragments 18S, 28SA, 28SD, H3, 12S, 16S, cytb (~3600...
Gryllus bimaculatus (Orthoptera: Gryllidae) is widely considered an excellent nutrient source for food and feed. Despite its economic importance, there limited information on the impact of temperature bionomics this cricket to guide effective sustainable mass production in geographical range. The biological parameters G . were investigated at eight different temperatures ranging from 20–40˚C. Insect Life-Cycle Modelling (ILCYM) program was used fit linear non-linear functions data describe...
In response to predation pressure, some insects have developed spectacular plant mimicry strategies (homomorphy), involving important changes in their morphology. The fossil record of provides clues the importance pressure deep past. Surprisingly, date, oldest confirmed records insect leaf are Mesozoic. Here we document a crucial step story adaptive responses by describing leaf-mimicking katydid from Middle Permian. Our morphometric analysis demonstrates that wings katydids can be...
Gryllus madagascarensis (Orthoptera: Gryllidae) is a cricket species that shows promise to mitigate food insecurity and malnutrition. But whether this will accept low- no-cost weeds agro by-products as feed, how these feeds affect its performance, remains unknown. This study assessed the acceptability of 66 weed (derived from single plant species) by adult G . compared results reference feed (chicken feed). We further examined 11 top acceptable products affected growth parameters The...
Abstract Cerebrospinal fluid‐contacting neurons (CSFcNs) occur in various brain regions of lower vertebrates. In mammals, they are restricted to medullospinal areas, and little is known about their projection sites. the present work, we investigated some morphofunctional characteristics such rat spinal cord by light electron microscopic immunocytochemistry. CSFcNs expressing P2X 2 subunit purinergic receptors were throughout cord, though more numerous at thoracolumbar sacral levels. These...
Abstract When the same complex trait is exhibited by closely related species, a single evolutionary origin frequently invoked. The stridulatory apparatus present in forewings of extant crickets, mole katydids, and prophalangopsids, currently interpreted as sharing common due to their similarity unique function. An alternative hypothesis convergent evolution these ensiferan groups has challenged this view, but remained controversial because competing interpretations wing venation. Here we...
Madagascar has a long history of using Orthoptera as food and feed. Our understanding the biological diversity this resource, its contemporary use, future potentials in is extremely limited. The present study contributes basic knowledge local uses edible Malagasy cultures. Data was collected with key informants 47 localities covering most ecoregions corresponding to 12 19 ethnic groups. are consumed throughout Madagascar. We report 37 species, which 28 new species records 24 world. Most...
Abstract Fossils are more and used in phylogenetic evolutionary studies either for clade calibration, or as terminals a dataset including morphological characters. The strength of these methodological advances relies however on the quality completeness fossil record. For crickets (Insecta, Orthoptera, Gryllidea), few ancient (pre-Cenozoic) well-preserved fossils known, except isolated wings often classified purely groups found Cretaceous amber. Here, we present two remarkable from...
A new native edible cricket species, Scapsipedus icipe Hugel and Tanga, has been described in Kenya for the first time. However, there is lack of information on suitable diets their effects developmental time, survival, weight gain, body length, growth index, preoviposition, oviposition, postoviposition, fecundity, egg eclosion period, adult emergence, longevity this which are prerequisite large-scale production. In study, six (wheat bran, soybean, fish offal, pumpkin leaf, carrot, maize...
