Nervous System News and Research

RSS

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.

Mathematical Mechanism Behind the Rugged Structures at Cell Boundaries

The mathematical and biological mechanisms underlying the rugged structures at cell boundaries present in tissues like the kidneys and nasal glands have been discovered.

UCF Scientists Develop a Digital Topographical Map of the Cardiac Sympathetic Neural Network

A team of UCF College of Medicine researchers has created a digital topographical map of the cardiac sympathetic neural network, the region that controls the body's heart rate and its "fight-or-flight" response.

New Peptide Blocks a Hyperactive Brain Enzyme Involved in Neurodegeneration

MIT neuroscientists have found a way to reverse neurodegeneration and other symptoms of Alzheimer's disease by interfering with an enzyme that is typically overactive in the brains of Alzheimer's patients.

Retinal Microvasculature may be a Potential Biological Indicator for Predicting Acute Mountain Sickness

This study is led by Dr.Ningli Wang and Dr.Yuan Xie (Beijing Tongren Hospital, Capital Medical University), they provide evidence that retinal microvasculature is a potential biomarker for cerebral microvasculature changes and acute mountain sickness(AMS) development during risk assessment of individuals at high altitudes.

Tiny Protein Interacts with Ion Channels to Make Our Eyes Sensitive to Dim Light

Using cryo-electron microscopy and mass spectrometry, researchers from PSI have deciphered the structure of an ion channel found in the eye while it interacts with the protein calmodulin – a structure that has eluded scientists for three decades.

Astrocytes in the Brain may Play a Key Role in Regulating Information

Long thought of as "brain glue," the star-shaped cells called astrocytes-;members of a family of cells found in the central nervous system called glial that help regulate blood flow, synaptic activity, keep neurons healthy, and play an important role in breathing.

Immune cells in human blood produce acetylcholine that regulates blood pressure and inflammation

Acetylcholine regulates blood flow, but the source of blood acetylcholine has been unclear. Now, researchers at Karolinska Institutet have discovered that certain T cells in human blood can produce acetylcholine, which may help regulate blood pressure and inflammation.

Common Epstein-Barr virus may be a trigger for multiple sclerosis

In 1868, French physician Jean-Martin Charcot, known as the founder of modern neurology, defined a disease entity in which multiple plaques formed in the brain and spinal cord, with varying physical symptoms, called Sclérose en plaques, or in English as multiple sclerosis (MS).

New type of neural implant could restore limb function to amputees

Researchers have developed a new type of neural implant that could restore limb function to amputees and others who have lost the use of their arms or legs.

Wearable microscopes produce real-time images of mouse spinal cord activity

The spinal cord acts as a messenger, carrying signals between the brain and body to regulate everything from breathing to movement.

Variations in methylation linked to age in the human sperm epigenome

A higher risk of reproductive and child health issues is linked to advanced paternal age. Increasing evidence points to age-related alterations in the sperm epigenome as one underlying cause.

DNA drugs help restore the normal processing of protein-encoding RNA

A protein named TDP-43 has been lost from its normal location in the nucleus of the cell in virtually all persons having amyotrophic lateral sclerosis (ALS) and in up to half of all cases of frontotemporal dementia and Alzheimer’s disease (AD).

Delaying paralysis in ALS by using designer DNA drug

In virtually all persons with amyotrophic lateral sclerosis (ALS) and in up to half of all cases of Alzheimer's disease (AD) and frontotemporal dementia, a protein called TDP-43 is lost from its normal location in the nucleus of the cell.

Study reveals the cellular composition and circuit organization of the locus coeruleus

A small nucleus in the brainstem called locus coeruleus (literally the "blue spot,") is the primary source of a major neuromodulator, norepinephrine (NE), an important mediator of the 'fight or flight' response in animals. However, very little is known about the local connections of this small albeit critically important group of neurons.

Age-related sarcopenia prevented by AAV1.NT-3 gene therapy

A new research paper was published on the cover of Aging (listed by MEDLINE/PubMed as "Aging (Albany NY)" and "Aging-US" by Web of Science) Volume 15, Issue 5, entitled, "AAV1.NT-3 gene therapy prevents age-related sarcopenia."

Novel platform identifies genes that control biologic processes

Inflammatory neurological diseases, such as multiple sclerosis (MS), can arise when cell-to-cell communication between cells in the central nervous system (CNS) goes awry. But exactly how this cellular crosstalk leads to the molecular changes that drive disease remain unknown.
