Increase in glial intracellular K+ in drone retina caused by photostimulation but not mediated by an increase in extracellular K+.

abstract：:Neurotrophin-3 (NT-3) regulates oligodendrocyte (OLG) differentiation by mechanisms that remain poorly understood. Exposure of OLGs to NT-3 induces a significant increase in the levels of myelin basic protein (MBP). However, we found that this stimulation occurs in the absence of measurable effects on MBP gene promote...
