Abstract:

Cerebrospinal fluid (CSF)-contacting neurons (CSF-N) located in the surface of both brain ventricles and the central canal (cc) in the spinal cord. The cc and CSF maintain a proliferative niche and play a vital role in development of the brain. The CSF-Ns sense chemicals changes and motion in the brain. The CSF rhythmic flow and pulsation can be observed both in the brain and spinal cord. It is demonstrated as a cardiac-related CSF pulsation and respiratory fluctuation. A new concept of CSF motion may be contrary to the classical one that the direction of CSF motion may vary in direction and may be dynamic in its location. The CSF pressure may also depend on the body position. Moderate music-making has been considered a potential approach for rehabilitative and restorative therapy of brain dysfunctions. Recently, we find that the CSF-Ns are also present in exterior CSF around the surface of the spinal cord. We hypothesize that CSF-N as mechanical sensors in the spinal cord could sense motion of the spinal cord. However, this hypothesis still lacks the study of whether somatic movements during music-making could affect CSF movement or circulation. The myodural bridge is a ligament connecting a pair of deep, upper-neck muscles to the dura mater, which envelops the arachnoid mater and contains the CSF surrounding the brain and the spinal cord. We presume that the somatic body movement with music-making would orchestrate the CSF motion with head movement, myodural bridge stretching and puling as well as spinal bending etc.
