This week's episode considers Transcranial Direct Current Stimulation, or tDCS, a means of modulating the brain’s function through “non-invasive” electrical stimulation. We will also talk about long term effects of concussion on football players. Happily, we are joined by Dr. Matthew Wright, who is an expert in these things and can help us navigate the mountains of conflicting information that abounds in both areas. Also, we must talk about our love for Prince, who passed away suddenly a few days prior to recording.
