cortical column

Attention, consciousness, and electrical wave activity within the cortical column.

A cortical column is understood as a group of cells that have the same receptive field.

Vernon Mountcastle's formulation of a cortical column is a basic element in the framework.

(2003) The subplate is required for functional maturation of visual cortical columns.

In contrast, large basket cells innervate somata in different cortical columns.

See also Calvin's Handbook on cortical columns.

A single HTM node may represent a group of cortical columns within a certain region.

In the adult, it forms a continuous smooth outer zone with a number of projections (cortical columns) that extend down between the pyramids.

In V1, and primary sensory cortex in general, neurons with similar tuning properties tend to cluster together as cortical columns.

Each HTM region consists of a number of highly interconnected cortical columns.

In 1978 Mountcastle proposed that all parts of the neocortex operate based on a common principle, with the cortical column being the unit of computation.

Hawkins posits that these cells will remain active for the duration of the learned sequence, even if the remainder of the cortical column is shifting state.

The cells from a single progenitor cell form a proliferative unit that creates one cortical column; these columns contain a variety of neurons with different shapes.

Hawkins predicts a cascade of predictions, when recognition occurs, propagating down the cortical column (with each saccade of the eye over a learned scene, for example).

It models cortical columns that tend to inhibit neighboring columns in the neocortex thus creating a sparse activation of columns.

These cortical microcircuits are grouped into cortical columns and minicolumns, the latter of which have been proposed to be the basic functional units of cortex.

HTMs attempt to model cortical columns (80 to 100 neurons) and their interactions with fewer HTM "neurons".

Thus, each "model neuron" or "artificial neuron" within this 2D-map is physiologically represented by a cortical column since the cerebral cortex anatomically exhibits a layered structure.

David Hubel and Torsten Wiesel proposed the classic ice-cube organization model of cortical columns for two tuning properties: ocular dominance and orientation.

The regions of inactive cortex that form between cortical columns were determined to be actively inhibited; administration of a GABA blocker stops columnar development.

Soon, it may be possible to measure blood flow in tiny areas called cortical columns, clusters of neurons that carry out a single function like detecting edges or direction of motion.

Later works have provided evidence of the presence of functionally distinct cortical columns in the visual cortex (Hubel and Wiesel, 1959), auditory cortex and associative cortex.

It has been impossible to find a canonical microcircuit that corresponds to the cortical column, and no genetic mechanism has been deciphered that designates how to construct a column.

He suggests that the neocortex has a hierarchy that allows for increasing abstraction from one vertical cortical column to the next, such that the vertical columns build off the levels below it.

Prior to this work, most modeling of cortical columns was in terms of somewhat opaque and clumsy "neural network" models-bandpass-filtered noise quickly became a standard modeling technique for cortical columnar structure.
