Relating to medical procedures or stimulation techniques that work through the skull without requiring surgical invasion, such as transcranial magnetic stimulation (TMS) used to treat depression and other neurological conditions.
From Latin 'trans-' (across/through) + 'cranial' (relating to the skull). The term emphasizes that these techniques work by passing through the skull rather than requiring surgical opening of the cranium.
Transcranial magnetic stimulation represents a major breakthrough in brain treatment because it can precisely target specific brain regions using powerful magnetic fields that pass harmlessly through the skull - imagine being able to 'tune up' specific brain circuits like adjusting the settings on a radio! Unlike ECT, patients stay awake and alert during treatment, and it's so precise that it can stimulate an area as small as a coin.
