In the previous paper the technical aspects of the mucin-clot prevention test which was standardized by McClean (1) have been described. Friou and Wenner (2) using the mucin-clot prevention test have demonstrated the clinical significance of an inhibitory substance in human serum capable of neutralizing an enzyme elaborated by a strain of hemolytic streptococcus. The amount of inhibitory substa...

where ε equals permittivity, εr equals relative permittivity, ε0 equals permittivity of free space (8.85 10 12 F Laboratory tests were conducted to simultaneously measure soil m 1), ε r equals dielectric constant (the real part of relawater content and salinity using a four-electrode Wenner array sensor. The sensor was modified to enhance the capacitive effect. Soil bulk tive permittivity), ε′′...

Many developing networks generate spontaneous network activity (SNA) that plays an important role in setting up functional circuitry, but how the proper level and pattern of SNA is itself maintained has not been clear. In this issue of Neuron, Gonzalez-Islas and Wenner show that SNA in the intact embryo regulates itself through a set of adaptive homeostatic plasticity mechanisms.
