A Dynamical Model for Receptive Field Self-organization in V1 Cortical Columns
نویسنده
چکیده
We present a dynamical model of processing and learning in the visual cortex, which reflects the anatomy of V1 cortical columns and properties of their neuronal receptive fields (RFs). The model is described by a set of coupled differential equations and learns by self-organizing the RFs of its computational units – sub-populations of excitatory neurons. If natural image patches are presented as input, self-organization results in Gabor-like RFs. In quantitative comparison with in vivo measurements, we find that these RFs capture statistical properties of V1 simple-cells that learning algorithms such as ICA and sparse coding fail to reproduce.

under the title \Models of Ocular Dominance and Orientation Columns." Reused by permission. ABSTRACT The formation of ocular dominance and orientation columns in the mammalian visual cortex is brieey reviewed. Correlation-based models for their development are then discussed, beginning with the models of Von der Malsburg. For the case of semi-linear models, model behavior is well understood: co...
متن کاملDynamics of Cortical Columns - Self-organization of Receptive Fields
We present a system of differential equations which abstractly models neural dynamics and synaptic plasticity of a cortical macrocolumn. The equations assume inhibitory coupling between minicolumn activities and Hebbian type synaptic plasticity of afferents to the minicolumns. If input in the form of activity patterns is presented, selforganization of receptive fields (RFs) of the minicolumns i...

The intracortical arborizations of neurons from the ventroposterolateral thalamic nucleus (VPL) in the cat were studied by intraaxonal injections of horseradish peroxidase (HRP) following identification of their receptive fields. In the primary somatic sensory cortex (SI) VPL cells terminated in different cytoarchitectonic areas according to their receptive field modality. Fibers excited by dee...
متن کاملA Reaction-Diffusion Model to Capture Disparity Selectivity in Primary Visual Cortex
Decades of experimental studies are available on disparity selective cells in visual cortex of macaque and cat. Recently, local disparity map for iso-orientation sites for near-vertical edge preference is reported in area 18 of cat visual cortex. No experiment is yet reported on complete disparity map in V1. Disparity map for layer IV in V1 can provide insight into how disparity selective compl...
متن کاملThe cortical column: a structure without a function.
This year, the field of neuroscience celebrates the 50th anniversary of Mountcastle's discovery of the cortical column. In this review, we summarize half a century of research and come to the disappointing realization that the column may have no function. Originally, it was described as a discrete structure, spanning the layers of the somatosensory cortex, which contains cells responsive to onl...
