Nervous System News and Research RSS Feed - Nervous System News and Research

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.

Researchers identify important therapeutic target for small cell lung cancer

UT Southwestern Medical Center researchers have identified a protein termed ASCL1 that is essential to the development of small cell lung cancer and that, when deleted in the lungs of mice, prevents the cancer from forming. [More]
Long-term antibiotic treatment slows progression of Alzheimer's disease through changes in gut bacteria

Long-term antibiotic treatment slows progression of Alzheimer's disease through changes in gut bacteria

Long-term treatment with broad spectrum antibiotics decreased levels of amyloid plaques, a hallmark of Alzheimer's disease, and activated inflammatory microglial cells in the brains of mice in a new study by neuroscientists from the University of Chicago. [More]
Scientists develop new optical fiber-based probe for brain temperature measurements

Scientists develop new optical fiber-based probe for brain temperature measurements

The brain is the most temperature-sensitive organ in the body. Even small deviations in brain temperature are capable of producing profound effects--including behavioral changes, cell toxicity, and neuronal cell death. The problem faced by researchers and clinicians is how to measure and understand the [More]

Study shows parvalbumin-interneurons in the amygdala influence fear memory encoding

Study shows parvalbumin-interneurons in the amygdala influence fear memory encoding

Fear memory encoding, the process responsible for persistent reactions to trauma-associated cues, is influenced by a sparse but potent population of inhibitory cells called parvalbumin-interneurons (PV-INs) in the amygdala, according to a study conducted at the Icahn School of Medicine at Mount Sinai and published online July 14 in the journal Neuron.
