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.

Systematic review identifies stress-induced biological triggers in oncology

Stress is a constant companion in the oncologist's office. It appears at the time of diagnosis, increases with each stage of treatment, and often does not resolve even after therapy formally ends. It accompanies therapeutic decisions, waiting for test results, fear of recurrence, and changes in daily functioning. Studies show that chronic stress can trigger biological processes that promote disease progression and weaken the body's defenses.

Multiple sclerosis prevalence in England doubles due to better diagnosis

Multiple sclerosis (MS) has more than doubled in recorded prevalence in England from 2000 to 2020, increasing by 6% per year, largely due to improved diagnosis and longer life expectancy, finds a new study by University College London (UCL) and Imperial College London researchers.

Liquid biopsy enables rapid diagnosis of Burkitt lymphoma in Africa

In a study published today in Nature Medicine, researchers from the University of Oxford and the Muhimbili University of Health and Allied Sciences (MUHAS) in Dar es salaam, Tanzania have shown that a minimally invasive "liquid biopsy" test can diagnose Burkitt lymphoma rapidly and accurately in sub-Saharan Africa, where delays in traditional testing often prove fatal.

Combination therapy shows promise for leptomeningeal metastasis in breast cancer

Patients with leptomeningeal metastasis (LM) have historically had few treatment options. Now, researchers from The University of Texas MD Anderson Cancer Center have found a combination of targeted therapies, tucatinib and trastuzumab, plus the chemotherapy drug, capecitabine, may improve symptoms and extend survival in some breast cancer patients with LM.

Study finds common brain mechanism behind different anesthesia drugs

When patients undergo general anesthesia, doctors can choose among several drugs. Although each of these drugs acts on neurons in different ways, they all lead to the same result: a disruption of the brain's balance between stability and excitability, according to a new MIT study.
