Cytoarchitecture of the cerebral cortex

WebThe cerebral cortex is the outer covering of the surfaces of the cerebral hemispheres and is folded into peaks called gyri, and grooves called sulci.In the human brain it is between two and three or four millimetres thick, and makes up 40 per cent of the brain's mass. 90 per cent of the cerebral cortex is the six-layered neocortex with the other 10 per cent … WebThe Principles of Comparative Cortical Cytoarchitectonics: The Basic Laminar Pattern of the Cerebral Cortex — Homogenetic and Heterogenetic Cortical Formations Regional Variations in Cell Structure of the Cerebral Cortex Particularities of the Cytoarchitecture in Different Animals
