In their study, subjects underwent 40 seconds of disruptive transcranial magnetic stimulation (TMS)-- in which a magnetic coil placed near the skull produced small electric currents in the brain that inhibited activity of the posterior TPJ — then spent 30 minutes completing a task.

Because they're stable, only a few nanometers in size, and need just small electric currents to transport them, skyrmions hold potential as the basis for ultra-compact and energy - efficient information storage and processing devices in the future. (sciencedaily.com)
Some of these patterns, called skyrmions, resist unraveling even when packed tightly together, and they can also be directed with small electric currents. (sciencedaily.com)
