TDCS Journal: Transcranial Direct Current Stimulation Log Book



Transcranial direct current stimulation (tDCS) is a form of neuromodulation that is increasingly being utilized to examine and modify a number of cognitive and behavioral measures. The theoretical mechanisms by which tDCS generates these changes are predicated upon a rather large neurophysiological literature. However, a robust systematic review of this neurophysiological data has not yet been undertaken.


tDCS data in healthy adults (18–50) from every neurophysiological outcome measure reported by at least two different research groups in the literature was collected. When possible, data was pooled and quantitatively analyzed to assess significance. When pooling was not possible, data was qualitatively compared to assess reliability.


Of the 30 neurophysiological outcome measures reported by at least two different research groups, tDCS was found to have a reliable effect on only one: MEP amplitude. Interestingly, the magnitude of this effect has been significantly decreasing over the last 14 years.


Our systematic review does not support the idea that tDCS has a reliable neurophysiological effect beyond MEP amplitude modulation – though important limitations of this review (and conclusion) are discussed. This work raises questions concerning the mechanistic foundations and general efficacy of this device – the implications of which extend to the steadily increasing tDCS psychological literature


This is a journal for documenting tDCS, with a quick guide to well known studied and researched montage placements. For those serious about getting into tDCS this book will be extremely helpful. The (Transcranial Direct Current Stimulation) journal is the first of it’s kind. It’s designed to help those who would like to journal their tDCS experience. This book features drawings of EEG 10-20 placement guide along with cranial drawings so you can circle, check, mark and accurately document your Montage sessions. There is two versions of this journal by Tobias Zimmerhoff. They’re basically the same. Only difference is they have different front covers, and this version has two more extra pages that display EEG Cranial Graphics. Both versions are great, and equally insightful. It just really comes down to personal preference
