To study combined effects of microwave irradiation and dextroamphetamine in studies of six rats that performed on a temporal reinforcement schedule. During one-hour sessions, only a response (depression of a small lever) that was delayed by 18 seconds or more after a preceding response was reinforced by food.
| Exposure | Parameters |
|---|---|
|
Exposure 1:
2.45 GHz
Modulation type:
pulsed
Exposure duration:
continuous for 0.5 h

the animals' behavior was tested: i) under the influence of microwave exposure ii) under the influence of dextroamphetamine iii) under the influence of a combination of microwave exposure and dextroamphetamine the experiments were done a) with 30 min exposure once b) with daily 30 min exposure except on days when dextroamphetamine was adiministered

The effects of dextroamphetamine on DRL behavior were potentiated by the microwave irradiation under both experimental conditions (single and multiple exposures), i.e. the maximal rate of responding occurred at lower dose of the drug.
