The devil is in the details. Together the spinal cord and the brain form the central nervous system (CNS). It is connected to the peripheral nervous system (PNS) which includes the nerves in our extremities. But, there are big differences between the two. Firstly the nervous cells (neurons) in CNS and PNS differ in ways such as their potential to regenerate. And, there are more cell types in the nervous system than just neurons. For a long time, those glial cells were regarded as mainly supporting cells (âgliaâ is ancient Greek name for glue).

Particle accelerator A particle accelerator is a device that uses electric fields to propel electrically charged particles to high speeds and magnetic fields to contain them. An ordinary CRT televison set is a simple form of accelerator. There are two basic types: linear (i.e. straight-line) accelerators and circular accelerators. In the circular accelerator, particles move in a circle until they reach sufficient energy. The particle track is typically bent into a circle using electromagnets. At present the highest energy accelerators are all circular colliders.
