BrodmannAreaAreas 1, 2 & 3 -PrimarySomatosensoryCortex (rostral tocaudal is 3, 1, 2)-Homunculusrepresentation: legsand trunk fold overmidline; arms andhands (most tissuededicated) are alongmiddle of strip; face(with much tissuededicated to lips)near bottom.
Area 4 - PrimaryMotor Cortex -motor homunculus
Area 5 -SomatosensoryAssociation Cortex
Area 6 - Pre-Motorand SupplementaryMotor Cortex (maycongtribute toplanning of complexcoordinatedmovements.)
Area 7 -SomatosensoryAssociation Cortex(involved in locatingobjects in space;where vision andproprioceptionconverge, enablingus to determinewhere objects are inrelation to parts ofthe body. Generally,use in visuo-motorcoordination such asin reaching to graspan object).)
Area 8 -Dorsolateralprefrontal cortexinvolved inmanagement ofuncertainty(increasinguncertaintyincreases activation

Area 9 -Dorsolateralprefrontal cortex -sustaining attentionand workingmemory. Lesionscause difficulty ininhibitingresponses.
Area 10 -Frontopolar area(involved instrategic processesof memory retrievaland executivefunction)
Area 11 -Orbitofrontal area(orbital and rectusgyri, plus part of therostral part of thesuperior frontalgyrus). involved inplanning, reasoning,and decisionmaking. Perhaps theonly corticalconstraint of thehypothalamus.
Area 12 -Orbitofrontal area(used to be part ofBA 11)
Area 13 - Insularcortex
Area 14 - Insularcortex
Area 15 - AnteriorTemporal Lobe

Area 18 -Secondary visualAssociation Cortex(V2) - bulk of thevolume of theoccipital lobe.
Area 19 - Tertieryvisual associationcortex (V3) - witharea 18, involved infeature-extraction,shape recognition,and visual attention.
Area 20 - InferiorTemporal gyrus -high-level visualprocesses andrecognition
Area 21 - MiddleTemporal gyrus -auditory processingand language,notably left side
Area 22 - SuperiorTemporal Gyrus,includes Wernicke'sarea in its posterior.Left side involved ingeneration andunderstanding ofwords. Right side,melody, pitch, andsound intensity.
Area 23 - Ventralposterior cingulatecortex
Area 24 - Ventralanterior cingulatecortex - motivation,will
Area 25 -Subgenual cortex
Area 26 -Ectosplenial area
Area 28 - PosteriorEntorhinal Cortex
Area 29 -Retrosplenialcingular cortex

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.
