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.

Research identifies significant spike in neurological disorders during the covid-19 pandemic

In 2021, neurological diseases affected 3.40 billion individuals worldwide, corresponding to 43.1 % of the global population. In China, rapid demographic shifts and lifestyle changes have contributed to a continued rise in the burden of stroke, dementia, and Parkinson's disease-a trend expected to persist.

Solving the mystery of ALS survival differences with new biological insights

Patients with ALS, or Lou Gehrig's disease, live an average of only three years after symptoms begin, though some can survive closer to 10 years. What drives these differences in survival has remained a mystery.

Pregnancy not linked to increased myasthenia gravis flare-up risk

For female participants with myasthenia gravis, pregnancy is not associated with an increased risk of serious flare-ups of the disease, or new or worsening symptoms, according to a study published May 13, 2026, in Neurology, the medical journal of the American Academy of Neurology.

Tracking the aging process across tens of millions of individual cells

While much is mysterious about the aging process, change over time remains its cornerstone. The biological shifts that accompany aging seemingly occur in many cells in the body.

Why is the US falling behind other high-income nations on survival?

A JAMA Network Open study found that the US recorded 12.7 million excess deaths compared with 17 peer high-income countries between 1999 and 2022. Circulatory and metabolic diseases drove much of the burden, while drug poisonings, alcohol-related deaths, and suicide sharply widened the gap among younger Americans.

Gene mapping highlights strong immune and brain connections in depression

Neurons and white blood cells differ greatly in shape, function, and location within the body. However, researchers at the University of São Paulo (USP) in Brazil discovered that certain genes are equally dysregulated in both cell types in people with depression.

New AI framework predicts how cells make fate decisions

Scientists at the Stowers Institute for Medical Research, Helmholtz Munich, the Technical University of Munich, and the University of Oxford have developed RegVelo - a new AI framework that simultaneously models cellular dynamics and gene regulation, enabling researchers to predict, simulate, and experimentally validate how cells make fate decisions.

Tumors exploit peripheral nerves to support cancer growth and spread

Tumors do not communicate only with immune cells, blood vessels, and stromal tissue. A growing body of evidence suggests that cancer can also co-opt the nervous system, reshaping the tumor microenvironment in ways that support growth, invasion, immune escape, and therapeutic resistance.

Cardiometabolic diseases remain leading cause of excess American mortality

Between 1999 and 2022, the US had substantially higher death rates than other wealthy nations, largely due to cardiovascular disease, metabolic diseases (including diabetes), Alzheimer's disease and related dementias, and drug and alcohol complications.
