note

currently the go to method to get the dosage of a TMS session is to link it to motor threshold (MT), AKA lowest stim needed to activate peripheral muscle when applied to motor cortex, as measure per subject. there are theoretical/practical problems to this approach including:

• optimal simulation site is hard to find/repeat when comparing across different muscles, as the MT’s for each muscle may differ.
• the real impacts of stimulation is unknown when targeting non-motor areas, as there is no observable effect to base it off of, and certain illnesses /age related declines can cause differences in the stimulation needed to induce expected effects. .
