To better understand the living dead, we must first understand the living brain. We can gain a fascinating insight into the behavior of zombies by studying neurological disorders and their treatments. However one such therapy, known as transcranial direct current stimulation (tDCS) has recently grown in popularity as scores of people have literally begun zapping their own skulls to treat everything from depression to schizophrenia.
This unusual craze has even spawned its own subreddit of faithful acolytes. But, despite the praise of amateurs, researchers have only just begun to explore this do-it-yourself phenomenon. Danny JJ Wang, a professor of neurology at the USC Mark and Mary Stevens Neuroimaging and Informatics Institute, recently studied the effects of this unconventional treatment on the human brain.
Once we reach the capability for reliable mapping of electromagnetic fields induced by tDCS in individual subjects with the proposed technical developments, our technique may open the door to a new field of individualized, precise, noninvasive neuromodulation using tDCS.
Neuromodulation is a medical therapy that attempts to restore the regular function of our nervous system and focuses on the relief of pain and control of symptoms, such as the involuntary and violent tremors often associated with the living dead. Of course, this is simply the first step in mapping the eventual effects of tDCS on the human brain.
