Table 1 Correlation between magnetic field effects and the JC presence in eggs or embryos

From: Cortex reorganization of Xenopus laeviseggs in strong static magnetic fields

  1. aMaximal field strength in T
  2. bTypes of magnets: E = electromagnet; SC = superconductor. Superscripts denote the application of field gradients, subscripts indicate radiofrequency pulsing as in magnetic resonance experiments.
  3. # The experiments were mainly performed on cysteine-dejellied eggs but jelly-coated embryos were mentioned to give essentially the same results.
  4. cEggs were dejellied not immediately after fertilization but about 1 h later. Description is ambiguous on whether field exposure started before or after dejellying.
