ABSTRACT:
To Confirm The Assumption That Repetitive Rapid-rate Transcranial Magnetic Stimulation (TMS) Induces The Functional And Structural Changes Analogous To Those Which Are Evoked During Electroconvulsive Shock (ECS), We Compared Now The Effects Of Treatments With TMS And ECS On The Behavioral Responses In Rats. We Also Tested The Reactivity Of The Cyclic Adenosine Monophosphate (AMP) Generating System In Cerebral Cortical Slices. TMS Similarly To ECS Shortened The Immobility Time In The Forced Swimming Test And Produced A Depression Of Responsiveness Of The Noradrenaline-stimulated Cyclic AMP Generating System, Although The Significance Of The Latter Effect Was Borderline. In Contrast To ECT, TMS Produced No Such Immediate Behavioral Effects As Analgesia And Depression Of The Early Phase Of Locomotor Activity. The Data Suggest That TMS Produces In Rats Some Responses That Are Regarded As Predictive For Antidepressant Activity, Similar To Those Produced By ECS, But Less Adverse Effects.
