We provide an inverse solution called the Brodmann Montage (tm) which is a neurogeometric solution. LORETapparently a geometric solution with neuroanatomical information attached after the solution is attained, inste

before.

The Magic of Biomathematics!

Note how a sinusoidal burst is found using the Brodmann montage which goes unseen or less clearlydelineated in Hjorth and Spherical Harmonic montages.
