Use It or Lose It Summary: 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. Source: LMU. An LMU study reveals that sound-evoked activity of neurons in the auditory systemContinue reading “Use It or Lose It”
The Aging but Resilient Brain: Keeping Neurons Happy
Notes: White matter in brain becomes less as we age. Men have more gray matter (math processing) while women have more white matter (finding patterns beyond math processing). Myelin sheath of the brain ensures electrical connections. A healthy gut leads to a healthy brain. What-makes-the-brain-works-and-why-it ages and becomes unhealthy [PPT] [PDF]
