Invitation to a Journey into Brainwaves Purchased about 5 years ago and stored at home, but I'm selling it because I don't use it. There are no writings, etc., and it's in relatively good condition, having been used only a few times. Please understand and accept that this is a used item. - Author: Tadahiko Ichikawa - Edition: 2nd Edition - Genre: Introduction to Brainwaves - ISBN: 978-4-7911-0599-1 Thank you for looking.
