 "The Foundation Anatomy Of Brain"

Exploring Through The Cerebral Cortex

Till now we have discussed the basic anatomy of the brain including the feature of corticalization. The major cerebral cortex and primary lobes have been discussed in older posts. This particular post will be revolving around the foundation anatomy of cerebral cortex. The advanced anatomical feature will get their place on future posts. 

  Getting on the topic of concern, we already know that very supreme and advanced cerebral cortex is one of the main reasons for the humans to be so smart compared to other life forms. As complex as the functioning of this layer is its anatomy.

 

The basic functions of cerebral cortex are-

• Memory

• Attention

• Language

• Perception

• Thought

• Awareness

• Consciousness

In most mammals cerebral cortex is folded to increase the surface area for neural activity. The folds on the upper layer of the cortex are called "Gyrus" and the groves formed are called "Sulcus".The interesting fact about human cerebral cortex is that, it is mostly buried in these sulcus. The human cerebral cortex is made up of wide spread grey matter and underlying layer of white matter. The most advance form of cerebral cortex that evolved over time is the mammalian neocortex. The cells of this cortex covers the largest part in the human brain. Evidently this cortex has six layers in the human brain.

The Layers of cerebral cortex are-

• Molecular layer- Consists of scattered neurons that are responsible for attention and learning

• External granule layer- Consists of pyramidal neurons and stellate cells.

• External pyramidal Layer- Consists of pyramidal and non pyramidal neurons

• Internal Granular Layer

• Internal Pyramidal Layer

• Multi Form Layer
