VIM DBS and Working Memory
This is part of a larger study for which participants have already completed memory and
thinking tests. In this study, investigators are trying to learn how deep-brain stimulation
affects memory skills in essential tremor (ET) patients. We are especially trying to figure
out how stimulation on each side of the brain may affect working memory.
