The purpose of this study is to see if a new brain stimulation technique, static magnetic field stimulation (tSMS), which involves holding a static neodymium magnet over the scalp, can influence normal rhythms of brain activity.

The investigator's primary objective is to determine the feasibility of modifying frontal brain activity using static magnetic fields. The investigator's will be examining the effects of static magnetic field of the spectral power of EEG data with healthy human participants.
This is a within-subjects design, where each participant will receive sham and active stimulation on the left and right frontal cortex. EEG data will be collected during each stimulation.
Healthy volunteers accepted: Yes
Only the study team can determine whether someone qualifies for participation.
Inclusion criteria
Exclusion criteria
A cylindrical neodymium magnet is placed above the scalp.
A cylindrical piece of nonferrous metal (brass). This is not attracted to magnets, and is identical in weight and appearance to active magnets.
Time frame: 4 minutes before stimulation, 10 minutes during stimulation, and 2 minutes after stimulation
Changes in the spectral power of the EEG before (2 min eyes-closed, 2 min eyes-open), during (eyes-open), and after stimulation (eyes-open)
Time frame: 4 minutes before stimulation, 10 minutes during stimulation, and 2 minutes after stimulation
Change in the ratio between the power in low frequency band and the power in high frequency band. As this outcome variable is a ratio between two items that are measured in microvolt^2, the ratio does not have a unit of measure.
