A new study from Edith Cowan University in Western Australia shows how transcranial random noise stimulation (tRNS) can improve human perception, which may boost neuroplasticity and learning.
tRNS is a noninvasive form of brain stimulation that sends a weak alternating current oscillating at random frequencies to the scalp using a pair of electrodes.
For their study, the research team has investigated the effects of one type of brain stimulation in a variety of settings and noted that this technique may have several applications.
Bein Rein, PhD, neuroscientist and postdoctoral scholar at Stanford, who was not involved in the study, says: “To date, the evidence suggests that tRNS can increase performance in certain learning, emotion perception, and visual detection tasks, while also improving sustained attention. However, tRNS could also be theoretically used for treating any condition characterized by regional changes in brain activity (such as stroke or depression).”
