Nervous System

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.

What is the Nervous System?

The nervous system is a complex network of neurons and cells that carry messages to and from the brain and spinal cord to various parts of the body.

Ultra-thin nanotechnology enables safe wireless stimulation for retinal degeneration

An international research team led by Prof. Dr. Sedat Nizamoğlu from the Department of Electrical and Electronics Engineering at Koç University has developed a next-generation, safe, and wireless stimulation technology for retinal degenerative diseases that cause vision loss.

Camera-based technology measures cardiopulmonary coupling without physical sensors

From a physiological perspective, heartbeats and breathing do not operate independently in the human body. Cardiac rhythm varies with the respiratory cycle, and the close interaction between the two is known as cardiopulmonary coupling (CPC).

New findings explain how lysosomal defects trigger neuronal energy failure

Together with colleagues from Stanford University, USA, researchers at the Leibniz Institute on Aging - Fritz Lipmann Institute (FLI) have, for the first time, created a comprehensive cell type-specific atlas of lysosomes in the brain, the cell organelles which are responsible for degradation and recycling processes.

Genetic study links vitamin B1 metabolism to gut motility and IBS risk

Research links thiamine metabolism to gut motility, identifying genetic markers that could lead to new therapies for IBS and related digestive disorders.

Brain cell precursors show constant myelin-making drive

In experiments with mice, Johns Hopkins Medicine scientists report new evidence that precursors of myelin-producing cells - one of the few brain cell types that continue to be produced in the adult brain - undergo differentiation widely and at a constant pace, rather than "as needed" in response to injury or advancing age.

Pregnancy-related stroke linked to long-term risk of cardiovascular events

Having an ischemic stroke during pregnancy or three months after pregnancy is associated with an increased risk of cardiovascular events like heart attack or second stroke, heart disease and depression later in life.

GLP-1 weight-loss drugs show early promise for treating addiction

This systematic review evaluates preclinical and clinical evidence on glucagon-like peptide-1 receptor agonists as potential treatments for substance use disorders. Findings show consistent reductions in drug- and alcohol-seeking behaviors in animal models, while human evidence remains limited, heterogeneous, and preliminary.

Suppressing brain immune cells enhances memory recall in young mice

Babies of every species from mouse to human rapidly forget things that happen to them-an effect called infantile amnesia.

Blocking microglia can prevent infantile amnesia

Scientists have found that blocking microglia (specialist immune cells in the brain) prevents infant forgetting ("infantile amnesia") and improves memory in mice, suggesting that microglia may actively manage memory formation and dictate what, and when, we forget.

Prolonged exposure to air pollution linked to elevated risk for ALS

Prolonged exposure to air pollution can be linked to an elevated risk for serious neurodegenerative diseases like ALS and seems to speed up the pathological process, report researchers from Karolinska Institutet in Sweden.

Brain structure changes linked to adaptability decline in aging adults

As people age, structural brain changes influence their ability to adapt to the environment. New from eNeuro, Tatiana Wolfe and colleagues at the University of Arkansas characterized changes in the brain across two periods of adulthood that may correspond to changes in adaptive behavior.

New blood biomarker tracks brain injury progression after ischemic stroke

A new blood marker reflects the extent of brain injury after an ischemic stroke and can predict patient outcomes months to years later.

Study reveals genetic signatures linked to HIV-related cognitive impairment

Using participant skin cells reprogrammed into neurons, Weill Cornell Medicine researchers have identified genetic signatures associated with HIV infection that may contribute to the cognitive impairment that often occurs in people living with HIV, even when the virus is controlled.

Cannabidiol could become a therapeutic tool for fetal alcohol spectrum disorder

Cannabidiol (CBD) could become a therapeutic tool to address some of the most frequent and disabling consequences of fetal alcohol spectrum disorder (FASD), a condition caused by alcohol exposure during pregnancy.

Research finds persistent prescribing of risky medications to older adults with dementia

Despite years of clinical guidelines warning against the practice, one in four Medicare beneficiaries with dementia is prescribed brain-altering medications linked to falls, confusion, and hospitalization, according to new research to be published January 12 in the peer-reviewed journal JAMA.
