Neuroscience is the scientific study of the nervous system, its functions and disorders. It is a multidisciplinary science that combines physiology, anatomy, molecular biology, developmental biology, cytology, psychology, physics, computer science, chemistry, medicine, statistics, and mathematical modeling to understand the fundamental and emergent properties of neurons, glia and neural circuits. The understanding of the biological basis of learning, memory, behavior, perception, and consciousness has been described by Eric Kandel as the "epic challenge" of the biological sciences.
An embryo is an initial stage of development of a multicellular organism. In organisms that reproduce sexually, embryonic development is the part of the life cycle that begins just after fertilization of the female egg cell by the male sperm cell. The resulting fusion of these two cells produces a single-celled zygote that undergoes many cell divisions that produce cells known as blastomeres. The blastomeres are arranged as a solid ball that when reaching a certain size, called a morula, takes in fluid to create a cavity called a blastocoel. The structure is then termed a blastula, or a blastocyst in mammals.
Acoelomorpha is a subphylum of very simple and small soft-bodied animals with planula-like features which live in marine or brackish waters. They usually live between grains of sediment, swimming as plankton, or crawling on other organisms, such as algae and corals. With the exception of two acoel freshwater species, all known Acoelomorphs are marine.
Wildlife conservation refers to the practice of protecting wild species and their habitats in order to maintain healthy wildlife species or populations and to restore, protect or enhance natural ecosystems. Major threats to wildlife include habitat destruction, degradation, fragmentation, overexploitation, poaching, pollution and climate change. The IUCN estimates that 27,000 species of the ones assessed are at risk for extinction. Expanding to all existing species, a 2019 UN report on biodiversity put this estimate even higher at a million species. It is also being acknowledged that an increasing number of ecosystems on Earth containing endangered species are disappearing. To address these issues, there have been both national and international governmental efforts to preserve Earth's wildlife. Prominent conservation agreements include the 1973 Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) and the 1992 Convention on Biological Diversity (CBD). There are also numerous nongovernmental organizations (NGO's) dedicated to conservation such as the Nature Conservancy, World Wildlife Fund, the Wild Animal Health Fund and Conservation International.
The Society for Neuroscience (SfN) is a professional society, headquartered in Washington, DC, for basic scientists and physicians around the world whose research is focused on the study of the brain and nervous system. It is especially well known for its annual meeting, consistently one of the largest scientific conferences in the world.
Nepenthes fusca, or the dusky pitcher-plant, is a tropical pitcher plant endemic to Borneo. It is found throughout a wide altitudinal range and is almost always epiphytic in nature, primarily growing in mossy forest.
Nepenthes vogelii is a tropical pitcher plant endemic to Borneo. It is thought to be most closely related to N. fusca.
Nothofagus fusca, commonly known as red beech is a species of southern beech, endemic to New Zealand, where it occurs on both the North Island and South Island. Generally it is found on lower hills and inland valley floors where soil is fertile and well drained. In New Zealand the species is called Fuscospora fusca.
May Roberta Berenbaum is an American entomologist whose research focuses on the chemical interactions between herbivorous insects and their host plants, and the implications of these interactions on the organization of natural communities and the evolution of species. She is particularly interested in nectar, plant phytochemicals, honey and bees, and her research has important implications for beekeeping.
Central nervous system diseases, also known as central nervous system disorders, are a group of neurological disorders that affect the structure or function of the brain or spinal cord, which collectively form the central nervous system (CNS). These disorders may be caused by such things as infection, injury, blood clots, age related degeneration, cancer, autoimmune disfunction, and birth defects. The symptoms vary widely, as do the treatments.
Connectomics is the production and study of connectomes: comprehensive maps of connections within an organism's nervous system. More generally, it can be thought of as the study of neuronal wiring diagrams with a focus on how structural connectivity, individual synapses, cellular morphology, and cellular ultrastructure contribute to the make up of a network. The nervous system is a network made of billions of connections and these connections are responsible for our thoughts, emotions, actions, memories, function and dysfunction. Therefore, the study of connectomics aims to advance our understanding of mental health and cognition by understanding how cells in the nervous system are connected and communicate. Because these structures are extremely complex, methods within this field use a high-throughput application of functional and structural neural imaging, most commonly magnetic resonance imaging (MRI), electron microscopy, and histological techniques in order to increase the speed, efficiency, and resolution of these nervous system maps. To date, tens of large scale datasets have been collected spanning the nervous system including the various areas of cortex, cerebellum, the retina, the peripheral nervous system and neuromuscular junctions.
Sminthuridae is a family of springtails of the order Symphypleona. Sminthurids are commonly referred to as globular springtails.
The evolution of nervous systems dates back to the first development of nervous systems in animals. Neurons developed as specialized electrical signaling cells in multicellular animals, adapting the mechanism of action potentials present in motile single-celled and colonial eukaryotes. Primitive systems, like those found in protists, use chemical signalling for movement and sensitivity; data suggests these were precursors to modern neural cell types and their synapses. When some animals started living a mobile lifestyle and eating larger food particles externally, they developed ciliated epithelia, contractile muscles and coordinating & sensitive neurons for it in their outer layer.
Tapinella is a genus of thick barklice in the family Pachytroctidae. There are at least 40 described species in Tapinella.
Truncatelloidea is a superfamily of snails, gastropod mollusks in the clade Caenogastropoda.
The dusky sleeper or brown spinecheek gudgeon is a species of fish in the family Eleotridae found in many Indo-West Pacific regions, from the coast of eastern Africa to Hawaii, where it can be found in lagoons, estuaries, and freshwater streams with muddy bottoms. This species can reach a length of 26 cm (10 in).
Thalassotalea is an aerobic and chemo-organo-heterotrophic genus of bacteria from the family Colwelliaceae which occur in the ocean and in sea ice.
Erythrodiplax fusca, the red-faced dragonlet, is a species of skimmer in the dragonfly family Libellulidae. It is found in Central America, North America, and South America.
Grégoire Courtine is a French neuroscientist and a professor at the École Polytechnique Fédérale de Lausanne (EPFL), where he is the co-director of the Defitech center for interventional neurotherapies (.NeuroRestore). His research focuses on the field of neurotechnology, with the aim to restore locomotor functions in patients with central nervous system disorders such as spinal cord injuries.
Mnesarchaea hudsoni is a species of primitive moths in the family Mnesarchaeidae. This species was first described by George William Gibbs in 2019, and is endemic to New Zealand. It is found in the Auckland, Coromandel, Bay of Plenty, Taupo, Gisborne, Hawkes Bay, Wairarapa and Wellington regions. This species inhabits cool, damp parts of native forest or lives alongside waterways and can be found at altitudes ranging from sea-level up to 800 m. Adults of this species are on the wing from February to April. M. hudsoni is very similar in appearance to its near relatives M. fusca and M. fallax but can be distinguished via differences in male genitalia.
