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.

New Study Challenges Traditional View of Axon Shape and Function

In a provocative new study, scientists challenge a fundamental tenet in neuroscience about the shape of axons -- the long, thin filaments radiating from nerve cells that transmit electrical signals from cell to cell – and propose a new model for understanding how information is transmitted in the brain.

New Discovery Redefines the Shape of Axons in Mammalian Brain Cells

Biology textbooks may need a revision, say Johns Hopkins Medicine scientists, who present new evidence that an armlike structure of mammalian brain cells may be a different shape than scientists have assumed for more than a century.

Study Reveals Molecular Mechanism Behind Neural Fate Commitment

The Wistar Institute's Alessandro Gardini, Ph.D., and lab have shed new light on how certain biological processes determine the development of neural cells. Their findings on a molecular "bridge" complex demonstrate a new level of detail in the understanding of early neural development -; which is fundamental for the further understanding of neurodevelopmental syndromes.
