I just read "Accidental Genius" by Darold A. Treffert, a featured article in August 2014's issue of #scientificamericanmagazine
. This article discusses the onset of #acquiredsavant
, using medical techniques such as tDCS (transcranial direct-current stimulation), DTI (diffusion tensor imaging, DTT (diffusion tensor tracking), MRI (magnetic resonance imaging), NIRS (near-infrared spectroscopy), and PET (positron-emission tomography) are used to study these savants.
tDCS is used to induce savantlike abilities in 40% of cases studied. DTI and DTT are used to determine what happens when brain circuits are turned up or down, to reveal the intricacies of the wiring inside a person's head. NIRS is a skullcap used to relay information to imaging software, this technique allows the patient to do activities that require movement rather constrained in an MRI. A recent development of PET helmet can now be used for monitoring at any time.
In a side article which discusses 'repetitive transcranial magnetic stimulation'. This technique delivers a pulsed magnetic field through the skull. This then turns off the brain circuit affected by this field, allowing for scientists to study the effects of a single hemisphere.
