Walking requires a huge number of signals between your brain and the muscles in your arms, chest, back, abdomen, pelvis and legs. Something that looks relatively straightforward is in fact incredibly complex. And the pace ...

In cases where cancer is fatal, 9 out of 10 times the culprit is metastasis. This is when the primary tumor has sent out cells, like seeds, and invaded other organs of the body. While medicine has made great progress in treating ...

Past neuroscience studies found that when the central nervous system (CNS) is damaged, for instance following a stroke or spinal cord injuries, the lesions become surrounded by borders of newly proliferated astrocytes.
Star-shaped glial cells, so-called astrocytes, are more than just a supporting cell of the brain. They are actively involved in learning processes and interact with nerve cells. But what exactly is it that astrocytes do?

A neuron (pronounced /ˈnjʊərɒn/ N(Y)OOR-on, also known as a neurone or nerve cell) is an excitable cell in the nervous system that processes and transmits information by electrochemical signalling. Neurons are the core components of the brain, the vertebrate spinal cord, the invertebrate ventral nerve cord, and the peripheral nerves. A number of specialized types of neurons exist: sensory neurons respond to touch, sound, light and numerous other stimuli affecting cells of the sensory organs that then send signals to the spinal cord and brain. Motor neurons receive signals from the brain and spinal cord and cause muscle contractions and affect glands. Interneurons connect neurons to other neurons within the same region of the brain or spinal cord. Neurons respond to stimuli, and communicate the presence of stimuli to the central nervous system, which processes that information and sends responses to other parts of the body for action. Neurons do not go through mitosis, and usually cannot be replaced after being destroyed, although astrocytes have been observed to turn into neurons as they are sometimes pluripotent.
