Thirty minutes of cell phone exposure showed no immediate effects on brain motor control in this small Japanese study.

Plain English Summary

Summary written for general audiences

Japanese researchers tested whether 30 minutes of cell phone radiation affects brain motor control by measuring electrical signals in the motor cortex (the brain region that controls movement) before and after phone exposure in 10 healthy volunteers and 2 multiple sclerosis patients. They found no changes in brain activity or motor function after phone exposure compared to fake exposure. The study suggests short-term cell phone use doesn't immediately impair the brain's ability to control muscle movement.

Study Details

We investigated whether the pulsed high frequency electromagnetic field (EMF) emitted by a mobile phone has short term effects on the human motor cortex.

We measured motor evoked potentials (MEPs) elicited by single pulse transcranial magnetic stimulatio...

MEPs to single pulse TMS were also recorded in two patients with multiple sclerosis showing temperat...
