Cortex cerebri est stratum externum hemisphaeriorum cerebri in mammaliis, ubi intra sex stratis I-VI variae cellulae nervales locatae sunt, simulque numerus neuronorum adeo magnus est, ut complicatio necessaria esset[1]. in cortice computationes extensivae expediuntur[2].

Cortex cerebri etiam substantia grisea dicitur. Dividitur cortex fissura longitudinali in corticem dextrum et sinistrum.

Anatomia microscopica[recensere | fontem recensere]

Distinguitur secundum criteria histologica inter neocorticem, isocorticem, et allocorticem[3].

Isocortex[recensere | fontem recensere]

Isocortice, qui tantum in mammaliis invenitur, laminae sex, numeris Romanis I-VI, sunt:

  • Lamina molecularis (I)
  • Lamina granularis externa (II)
  • Lamina pyramidalis externa (III)
  • Lamina granularis interna (IV)
  • Lamina pyramidalis interna (V)
  • Lamina multiformis (VI)
