The brain's forgotten glial cells

For a long time, researchers have neglected the 100 million glial cells found in our brains, but that is no longer the case. Now they have discovered that the glial cells cleanse the brain of waste.

Study reveals novel role for the Pin1 molecule

Synapses are "dynamic" things: they can regulate their action in neural processes related to learning, for example, but also as a consequence of diseases. A research team – led by SISSA – has demonstrated ...

How rabies "hijacks" neurons to attack the brain

Rabies causes acute inflammation of the brain, producing psychosis and violent aggression. The virus, which paralyzes the body's internal organs, is always deadly for those unable to obtain vaccines in time. ...

Neuron

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.
