WebShapiro-Wilk Test. The Shapiro-Wilk test is a test for normal distribution exhibiting high power, leading to good results even with a small number of observations.In contrast to other comparison tests the Shapiro-Wilk test is only applicable to check for normality. The basis idea behind the Shapiro-Wilk test is to estimate the variance of the sample in two ways: … WebConnexin 43, an astroglial gap junction protein, is enriched in perisynaptic astroglial processes and plays major roles in synaptic transmission. We have previously found that astroglial Cx43 controls synaptic glutamate levels and allows for activity-dependent glutamine release to sustain physiological synaptic transmissions and cognitiogns. …
