Cortical Columns
نویسندگان
چکیده
The most prominent feature of the architecture of the cortex is its horizontal organization into layers. Each layer contains different cell types, and forms different types of connections with other neurons. However, a strong vertical organization is often also apparent: neurons stacked on top of each other through the depth of the cortex tend to be connected and have similar response properties despite residing in different layers. This type of vertical structure is called a cortical column, and has been hypothesized to represent a basic functional unit for sensory processing or motor output. Columnar organization has been most extensively studied in the somatosensory and visual systems.

Modeling Cortical Activity: Cortical Columns
The aim of the talk is to introduce some notions about cortical modeling with a focus on cortical columns. In the first part, I introduce cortical columns from a biological point of view and point out why the notion of cortical column is complex. In the second part, I describe Jansen’s model of a single cortical column and discuss its adequacy to biological facts. The third and last part shows ...
متن کاملRules for the cortical map of ocular dominance and orientation columns
Three computational rules are sufficient to generate model cortical maps that simulate the interrelated structure of cortical ocular dominance and orientation columns: a noise input. a spatial band passfilter. and competitive normalization across all feature dimensions. The data of Blasdel from optical imaging experiments reveal cortical map fractures, singularities. and linear zones that are f...
متن کاملExcitation/Inhibition Patterns in a System of Coupled Cortical Columns
We study how excitation and inhibition are distributed mesoscopically in small brain regions, by means of a computational model of coupled cortical columns described by neural mass models. Two cortical columns coupled bidirectionally through both excitatory and inhibitory connections can spontaneously organize in a regime in which one of the columns is purely excitatory and the other is purely ...
متن کاملCortical Columns and Planning Models
The cortical column hypothesis is described along with backing evidence. Proposals for the functional properties of columns are reviewed, namely those based on construction of columnar models and networks of columns. An attempt is made to tie this knowledge into that of an existing model of planning, the TELOS model.
متن کاملThalamo-cortical interactions modeled by weakly connected oscillators: could the brain use FM radio principles?
We consider all models of the thalamo-cortical system that satisfy the following two assumptions: (1) each cortical column is an autonomous oscillator; (2) connections between cortical columns and the thalamus are weak. Our goal is to deduce from these assumptions general principles of thalamo-cortical interactions that are independent of the equations describing the system. We find that the ex...
متن کاملCellular organization of cortical barrel columns is whisker-specific.
The cellular organization of the cortex is of fundamental importance for elucidating the structural principles that underlie its functions. It has been suggested that reconstructing the structure and synaptic wiring of the elementary functional building block of mammalian cortices, the cortical column, might suffice to reverse engineer and simulate the functions of entire cortices. In the vibri...
