A TMS Experiment

Transcranial Magnetic Stimulation simulates brain lesions, but lacks spatial resolution and is restricted to regions of cortex directly below the skull.

Maybe we can take an analog from chemotherapy to expand the limits of the tool. One strong laser kills tumor and all tissue above and below tumor. Three weak lasers in different positions all intersecting at the tumor kill only the tumor (sort of).

Perhaps lesioning 5 (e.g.) different regions that, between them, account for >50% of the input to one (potentially small and buried) region would provide a mechanism by which TMS can access regions otherwise inaccessible to it. With the appropriate controls (ugh).
