spinal cord

An Itch to Scratch

Researchers have discovered a dedicated neural pathway that transmits the itchy feeling triggered by light touch.
This shows two nerves (stained in red and green), which are responsible for transmitting information from the hair cells to the brain and from neurons (small green dots) that alter hair cell sensitivity.

Maintaining the Balance

A new study reports on how signals from the spinal cord adjust the sensitivity of hair cells in the inner ear to accommodate shifts in head position and to insure balance is maintained.
