Researchers have identified two proteins that prevent the formation of scars in the brain and help promote the regeneration of new neural tissue.
Researchers directly measured oxygen levels in an intact brain and correlated it with neural activity. During normal activity, only 50% of oxygen is used for neural activity, the remaining 50% is required for glial cells and maintaining the metabolic rate of other nerve cells.
LMU researchers report neural activity in the auditory system has a direct effect on myelination. Higher levels of neural activity resulted in the formation of thicker myelin sheaths and enhanced speed of signal transmission.
