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.

Income and social disparities found to influence dementia risk factors

People with lower incomes and people from racial and ethnic historically underrepresented groups in clinical studies are more likely to have modifiable risk factors for dementia, factors that could be changed to lower their risk, according to a study published November 12, 2025, in Neurology, the medical journal of the American Academy of Neurology.

Switching APOE4 to APOE2 in adult mice reduces Alzheimer’s pathology and improves memory

Replacing APOE4 with APOE2 in adult mice rapidly reshapes brain lipids and gene expression, even after development is complete. This switch, especially when targeted to astrocytes, reduces amyloid burden, dampens gliosis, and improves associative memory despite E2-like peripheral lipid risks.

Listening to slow-tempo music may boost sleep quality for people over 50

Music therapy significantly improves sleep quality in adults aged 50 and above, showing a moderate-to-large effect compared with control conditions. However, high heterogeneity and methodological weaknesses mean the evidence remains of very low certainty and requires confirmation in larger, standardized trials.
