ABSTRACT:
The Prefrontal Cortex Plays An Important Role In Central
Motor Control. We Have Examined Whether Prefrontal
Repetitive Transcranial Magnetic Stimulation (rTMS)
Induces Changes Of Motor Cortex Excitability Determined
By Motor Evoked Potentials (MEPs) Following
Single-pulse TMS. We Studied 18 Healthy Volunteers
Stimulated At 5 Hz With 10% Subthreshold Prefrontal Vs.
Occipital RTMS For 12 S. MEPs From The Flexor Carpi
Radialis Muscle After Single-pulse Vertex Stimulation Were
Recorded During RTMS At 0, 4, 8, And 12 S. MEP Areas
Decreased Significantly After 8 S Of Prefrontal RTMS (P <
0. 05) But Not After Occipital RTMS. We Conclude That
RTMS Of The Prefrontal Cortex May Inhibit The Primary
Motor Areas. Copyright 2000 John Wiley Sons, Inc.
