No less than 16 different types of nerve cells have been identified by scientists in a new study on the human sense of touch. Comparisons between humans, mice and macaques show both similarities ...

By generating and comparing animal models of demyelinating neuropathies to patient's biopsies, we and others have determined that laminins are required for 'radial sorting' of axons in early ...

At the level of the first rib, the lower cervical nerve roots combine to form the 3 trunks of the brachial plexus. The lowest trunk is formed by the union of C8 and T1, and this trunk lies ...
