What gives us fingertip dexterity?
biology | nervous system | neurobiology | neuroscience | scienceIn a novel experiment, a USC biomedical engineer examines the intricate circuitry between hand manipulation skills and specialized neural circuits in the brain Quickly moving your fingertips to tap or press a surface is essential for everyday life to, say, pick up small objects, use a BlackBerry or an iPhone.
Scientists restore walking after spinal cord injury
bioengineering | biotechnology | nerves | nervous system | neurobiology | neuroscience | regeneration | regenerative medicine | scienceSpinal cord damage blocks the routes that the brain uses to send messages to the nerve cells that control walking. Until now, doctors believed that the only way for injured patients to walk again was to re-grow the long nerve highways that link the brain and base of the spinal cord.
Researchers take first steps towards spinal cord reconstruction following injury
biology | nerves | nervous system | neurobiology | neuroscience | stem cells | tissue engineeringA new study has identified what may be a pivotal first step towards the regeneration of nerve cells following spinal cord injury, using the body’s own stem cells. This seminal study, published in th
Subclavian loop
nervous systemSubclavian loop (ansa subclavia), also known as Vieussens' ansa after French anatomist Raymond Vieussens (1635-1715), is a nerve cord that is a connection between the middle and inferior cervical ganglion, and forms a loop around the subclavian artery.

biomedical | nerves | nervous system | neurons | neuroscience | regeneration | regenerative medicineFibrinogen, a blood-clotting protein found in circulating blood, has been found to inhibit the growth of central nervous system neuronal cells, a process that is necessary for the regeneration of the spinal cord after traumatic injury.
Nanomedicine opens the way for nerve cell regeneration
biotech | biotechnology | nanomedicine | nanoparticles | nanotech | nanotechnology | nerves | nervous system | neuroscienceThe ability to regenerate nerve cells in the body could reduce the effects of trauma and disease in a dramatic way. In two presentations at the NSTI Nanotech 2007 Conference, researchers describe the use of nanotechnology to enhance the regeneration of nerve cells.
