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.

Cancer and the Nervous System: Tumor Growth, Metastasis, and Neurobiology

Cancer neuroscience reveals a bidirectional relationship in which neural circuits, neurotransmitters, neurotrophic factors, and immune signaling can shape tumor growth, invasion, and metastasis. Tumors can, in turn, remodel nerves and exploit neural pathways, creating new opportunities and challenges for cancer therapy.

Workplace exposure to petroleum-based lubricants linked to higher MS risk

Exposure to petroleum-derived lubricants at work, including engine oil, hydraulic oil and cutting fluids used to cool or lubricate metal during metalworking, is associated with higher odds of multiple sclerosis (MS), according to a study published November 4, 2026, in Neurology, the medical journal of the American Academy of Neurology.

Longer reproductive lifespan and hormonal history may influence brain vascular health

A longer reproductive lifespan and a history of using birth control pills or menopausal hormone therapy were associated with certain signs of blood vessel health in the brain, according to a study published November 4, 2026, in Neurology, the medical journal of the American Academy of Neurology.

Faulty cellular recycling may link pulmonary arterial hypertension to brain damage

A commentary in The Journal of Clinical Investigation examines evidence linking pulmonary arterial hypertension (PAH) to cerebellar abnormalities, focusing on impaired lysosomal lipid metabolism, oxysterol accumulation, and microglial inflammation. Findings from human imaging, mouse models, and cultured cells suggest that NCOA7 may help protect against these changes, although the proposed mechanisms and therapeutic implications require further investigation.

Researchers explore why male and female brains adapt differently to overeating

Overeating alters neural pathways involved in feeding and metabolism, but how fast do these adaptive changes occur? And do these adaptations occur similarly in males and females?

New pediatric consensus standardizes surgical management of Wilms tumor

WT outcomes have improved substantially through progress in molecular diagnosis, chemotherapy, radiotherapy, and surgery. Yet surgical management remains inconsistent, especially for large tumors, adjacent-organ invasion, intravascular extension, nephron-sparing surgery (NSS), and lymph node biopsy.

Excessive exercise disrupts dopamine regulation in the brain, study finds

Excessive physical exercise affects more than just the muscles; it can also alter brain chemistry. A new study published in the journal Neuroscience revealed that exhaustive training without adequate rest alters the regulation of dopamine in the hippocampus, a brain region closely linked to memory and the regulation of emotions.

Mosquito bite prevention helps protect children from West Nile virus

In warm climates like Southern California, multiple species of mosquitoes can bite year-round. While telltale red, itchy bumps are the most common side effect of mosquito bites, these pests can also pass diseases, like West Nile virus, on to humans.
