multiform layer

The dendrites of these cells are covered by substance p immunoreactive (S.P.I) axons up into layer III (multiform layer) .

It is a relatively undifferentiated cortical area that Brodmann regarded as part of the insula because of the relation of its innermost multiform layer (VI) with the claustrum (VICl).

The fourth, fifth and sixth layers, or the Internal Granular layer, Internal Pyramidal layer, and Polymorphic or Multiform layer respectively, are formed during mouse E11.5 to E14.5.

Located in the posterior of the insular cortex, Brodmann area 13 shares with other parts of the insular cortex a wide molecular layer (I) and very wide multiform layer (VI).

Layer VI, the Polymorphic or multiform layer, contains few large pyramidal neurons and many small spindle-like pyramidal and multiform neurons; layer VI sends efferent fibers to the thalamus, establishing a very precise reciprocal interconnection between the cortex and the thalamus.
