Where internal milieu meets with extrapersonal space

INTERNAL MILIEU

1-Simplest and differentiated type of cortex:
basal forebrain structures (ventral and medial surfaces);
Corticoid (cortexlike structures)
-Septal nuclei
-Substantia Innominata
-Amygdaloid complex

2- Allocortex has moderately differentiated layers.
Archicortex: Hippocampus
Paleocortex: Piriform cortex (primary olfactory cortex)

CORTICOID + ALLOCORTEX = LIMBIC ZONE OF CORTEX

3- Paralimbic zone (mesocortex) :
Intercalated between isocortex and allocortex (transitional zone)
Periallocortical structures of the paralimbic areas.

Five major paralimbic formations:
-caudal orbitofrontal cortex
-insula
-temporal pole
-parahippocampal gyrus (entorhinal etc.)
-cingulate complex

Directing drive and emotion to the appropriate extrapersonal and intrapsychic targets
Paralimbic cortex acts as a relay between sensory association cortices and the limbic zone of the cortex

------------ --------- ---------
This zone is the neural bridges that link the
internal milieu (inner world)
and extrapersonal space (outer world),
enabling the individual's need to be dyscharged
according to the limitations of the environment.
Integration of multimodal knowledge (heteromodal)
with drive and emotion (paralimbic)
--------- --------- --------- --

4-Heteromodal association cortex
-Perceptual elaboration and motor planning
Receives convergent input from multiple unimodal areas especially downstream
unimodal areas

5-Unimodal association cortex
-Modality spesific elaboration and encoding of sensory input.

Peristriate region (18, 19) upstream unimodal association area
Inferotemporal cortex (20, 21) : downstream unimodal association area

6-Primary sensory and motor cortices
-idiotypic, homogenos, and dedicated

EXTRAPERSONAL SPACE
