relaxation, conductivity, and other properties for human tissue. IT’IS maintains a free, easily accessible, and dynamically evolving database of dielectric properties of biological tissues. Find average tissue-specific electrical conductivities at low frequencies of < 120 Hz of more than 100 human tissues in this table, with range and standard deviation.

TMS-SMART (Meteyard & Holmes, 2018) is a method to select stimulation sites for human TMS studies which allows you to control for the subjective annoyance, pain, and muscle twitches, as well as for visible twitches and reaction time changes associated with single-pulse TMS at 43 different sites on the scalp. This website allows you to browse the data visually, and to retrieve suggested control site locations.
