Study Type		In Vivo
Model		1.2, 2.4, 7 MHz exposure to cockroaches and analysis of navigational behavior
Details		Cockroaches (n = 11) were exposed to both a static magnetic field and either 1.2, 2.4, or 7 MHz (larmor frequencies of certain radical pair disruptions) at up to 44 nT for 2 x 45 minute study periods in 150mm Petri dishes using a Helmholtz coil exposure system. The authors report exposure disrupted the ability of the insects to orient themselves with respect to the static field (representing the earths geomagnetic poles and observed as the number of turns or circles performed during behavioral analysis). The maximal effect was observed at 1.2 MHz co-exposure at 14-18 nT. The authors suggest orientation in insects may be due to radical pair reactions of photosensitive molecules in a manner similar to birds.
