Exponential functions of the percentage of the maximum current density magnitude on the surface of the cortex of each model, relative to the healthy head model, as a function of distance into the brain model for each evaluation line

Evaluation line-coil position	Exponential trend line
Center line-MS	y = 139.54e^−0.0655x
Caudal line-MS	y = 138.74e^−0.0628x
Rostral line-MS	y = 128.1e^−0.0458x
Dorsal line-MS	y = 137.42e^−0.0631x
Ventral line- MS	y = 112.07e^−0.0225x
Center line -DLPC	y = 133.5e^−0.0492x
Caudal line-DLPC	y = 140.92e^−0.0584x
Rostral line-DLPC	y = 131.87e^−0.0531x
Dorsal line-DLPC	y = 135.69e^−0.054x
Ventral line- DLPC	y = 145.73e^−0.0542x

Note that cortex starts at approximately 6 mm, dependent upon evaluation line
