|Setup||The microwave instrument described in [Stavinoha et al., 1977] was tuned for each mouse using an EH tuner, a milliwatt power source, and crystal receiver.|
|Sham exposure||A sham exposure was conducted.|
|Additional info||At various intervals after the pulse, some animals were killed by a second pulse of 250 ms duration.|
Brain temperature was increased by 2°C in 15 ms and 4°C in 25 ms. Immediately after irradiation, the mice became hypokinetic but began recovering within 5 minutes. The 25 ms pulse caused a significant decrease in acetylcholine content of the whole brain, probably owing to increased permeability of the membrane.
