The nervous system is an organ system containing a network of specialized cells called neurons that coordinate the actions of an animal and transmit signals between different parts of its body. In most animals the nervous system consists of two parts, central and peripheral. The central nervous system contains the brain and spinal cord.
A recent study led by the University at Buffalo proposes a novel role for the huntingtin protein (HTT), which leads to Huntington’s disease when mutated.
For the neuronal cell types’ categorization as more complicated creatures, the genetic fingerprint of Nematostella vectensis—the sea anemone—reveals that the members of this evolutionarily very ancient animal phylum employ identical gene cascades.
The first large-scale genomic study of musicality revealed 69 genetic variations linked with beat synchronization, which denotes the ability to move in time with the beat of the music.
Solitary bees that ingested the pesticide clothianidin when foraging from rapeseed flowers became slower. In addition, the strawberries pollinated by these bees were smaller. This is shown by a new study from Lund University in Sweden.
It is well known that strawberries whose blossoms have been visited by bees grow larger; however, it is not yet understood how neonicotinoid pesticide exposure to bees affects strawberry development.
Cognitive decline brought on by aging is a precursor to dementias like Alzheimer’s and can have a significant impact on a person’s ability to carry out essential daily tasks.
Researchers from Tohoku University have now shown that the consolidation and extinction of contextual fear conditioning alter the microglial genes connected to the synapse—structures that permit neurons to communicate with one another.
The creation and movement of an essential class of molecules in human cells are now better understood according to a recent study.
The first spatiotemporal cellular atlas of axolotl (Ambystoma mexicanum) brain growth and regeneration, created by a multi-institute research team under the direction of BGI-Research, reveals how brain damage may recover itself.
Scientists at the Francis Crick Institute have identified a group of latent stem cells that respond to injury in the central nervous system of mice. If a similar type of cell exists in humans, they could offer a new therapeutic approach to treat brain and spinal cord injuries.
It could be the world's tiniest EEG electrode cap, created to measure activity in a brain model the size of a pen dot. Its designers expect the device to lead to better understanding of neural disorders and how potentially dangerous chemicals affect the brain.
A research group from MedUni Vienna’s Center for Brain Research has identified key cells that control data communication between parts of the brain.
Scientists have for the first time photographed an autoantibody coupled to a receptor on the surface of a nerve cell using the Cryo-Electron Microscopy Facility at UT Southwestern.
The octopus is an extraordinary organism with exceptional brain complexity and cognitive abilities that are unmatched by other invertebrates. So much so that it resembles vertebrates in certain ways more than it does invertebrates.
Even with plenty of fish in the sea, sea dragons stand out from the crowd. The funky, fabulous fish are bedecked with ruffly leaf-like adornments. Their spines are kinked.
A recent genetic finding supports the theory that abnormal lipid (fat) transport pathways inside brain cells cause motor neuron degenerative disorders.
Researchers at the University of California San Diego and the Salk Institute for Biological Studies have developed a tiny neural probe that can be implanted for longer time periods to record and stimulate neural activity, while minimizing injury to the surrounding tissue.
When genes mutate, serious diseases of the human nervous system can result. Scientists from Leipzig University and the University of Würzburg have now used fruit flies to show how, in addition to the negative impact, mutation of a neuronal gene can have a beneficial impact—higher IQ in humans.
North Carolina State University researchers have shown that neuron-like cells produced from human stem cells may be used to examine alterations in the neurological system linked to addiction.
Squid, octopus, and cuttlefish – even to scientists who study them – are wonderfully weird creatures. Known as the soft-bodied or coleoid cephalopods, they have the largest nervous system of any invertebrate, complex behaviors such as instantaneous camouflage, arms studded with dexterous suckers, and other evolutionarily unique traits.
