Increased cortical inhibition in depression: a prolonged silent period with transcranial magnetic stimulation (TMS).
Steele JD., Glabus MF., Shajahan PM., Ebmeier KP.
Motor slowing in depression may be associated with a relative dopaminergic (DA) deficit. Bradykinesia in Parkinson's syndrome is associated with an abnormally short silent period (SP) using transcranial magnetic stimulation (TMS). We hypothesized that depression would also be associated with a short SP.
