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.

Disseminated cancer cells hijack crucial iron micronutrients to survive

In order to survive within the remote and harsh anatomical microenvironments of the central nervous system, the disseminated cancer cells that cause rare yet deadly leptomeningeal metastases (LM) hijack crucial iron micronutrients from native macrophages, researchers report.

TMEM106B gene reveals the causes of neurodegenerative diseases

Across the globe, approximately 50 million people are living with dementia. The two most common forms are Alzheimer's disease and frontotemporal lobar degeneration (FTLD), which develop when neurons in specific parts of the brain stop functioning - triggering memory loss and other behavioral or personality changes.
