In the first series of experiments, explorative behavior during exposure was investigated in following groups: an exposure group, a control group and a sham exposure group (exposed to a 30-40 mW electricity supply device). In the second series, anxiety behavior was investigated one day after exposure (30 min) in an elevated plus-maze (exposed group and control group). Each group consisted of 10-12 male mice.
|Exposure duration||continuous for 15 min.|
|Exposure duration||continuous for 30 min.|
In the first series of experiments, the exposed animals showed a decreased explorative activity compared to the control group. In the second series, the number of entries into the central area was lower and the number of entries in the closed arms was higher in the exposed group, no entry into the open arms was observed.
The authors concluded that mice perceived terahertz waves even during short-term exposure and showed increased anxiety on the day after 30-min exposure.
