Lamination Of Neurons

A laminated organization is likely to be essential for cortical function as.
Lamination of neurons. Cortical lamination is not unique to neocortex. In the retina like in most other brain regions developing neurons are arranged into distinct layers giving the mature tissue its stratified appearance. In this model lamination cues such as robo2 could speed circuit assembly simply by increasing the likelihood of contact between matching pre and postsynaptic neurons. Lamination of neurons and fibre projections is a fundamental organizational principle of the mammalian cerebral cortex.
Evolutionary origins of neocortical neurons and lamination. This process needs to be highly controlled and orchestrated as neuronal layering defects lead to impaired retinal function. From an evolutionary perspective it began with simple three layer cortex.
