"If you have a cortical column
that has a chunk of human or rodent cortex, you're going to be able to accomplish more computations faster with the human architecture versus the rodent architecture," he says.
Distribution of the number of NeuN+ cells observed in a 1-mm cortical column
in different layers of the motor area.
This type of single cortical column model with altered parameters is able to generate realistic patterns such as alpha rhythms and epileptiform spikes in EEG.

Since speech perception is a higher-level perception process, it is permissible to suggest the following extrapolation: each node (or nection) in the neurocognitive system of an individual can be implemented as a cortical column. Within the linguistic system, every nection/cortical column has a highly specific function.
By the end of section 2 we said that one single nection can be implemented as one single cortical column, and cortical columns consist of about 110 neurons (including both excitatory and inhibitory neurons).
A vertically organized series of connected neurons that form a brain circuit, the cortical column is considered the elementary building block of the cortex, the part of the brain that is responsible for many of its higher functions.
"This is the first complete 3D reconstruction of a realistic model of a cortical column," said Marcel Oberlaender, PhD, first author on the study.
