摘要: Abstract Blue light (496 nm; threshold intensity approximately 1500 Lux) induces a transient frequency decrease of oscillatory contraction automaticity in Physarum. Many, but not all specimens react by an increase the force amplitude longitudinal contraction. The spectral region 496 nm provokes photophobic response plasmodia. blue reaction radial and activities decreases with increasing distance from irradiated area. light-induced can be used for experimental phase shifting, e.g., when studying nature pathway signal transmission spatial synchronization contractile activities.
