Abstract
This five-layered model consisting of 180 neurons is aimed at simulating some elementary functions of primary visual cortex of mammals in form detection.
Its main achievements are:
-
1.
Detection of points, lines, simple geometric figures in the V1
-
2.
Abstraction of 19 different qualities of geometric figures
-
3.
Simulation and rational explanation of processing of peripheral stimuli in the V1, explanation of mechanism of origin of visual ERPs, including P300 wave
-
4.
Simulation and explanation of the nature and build up of the cognitive function within V1 and its possible relation to long-term memory
-
5.
The model is based partly on Hebb-type synapses, illustrates the role of neuronal assemblies, sheds light on the functional relationship of excitatory and inhibitory neurons, in their conformity with special tasks of different cortical layers.
