Abstract

Could the prior development of the retinotopic map account for the radial bias in the orientation map in V1?

Highlights

  • The development of the retinotopic map is presumed to precede the development of the orientation map in V1 in primates

  • The afferent, lateral excitatory (Eij,kl) and lateral inhibitory (Iij,kl) weights adapt based on a normalized Hebbian mechanism

  • The retinotopic map developed, biases the initial configuration of the orientation map since all the bars given during the initial training are

Summary

Introduction

The development of the retinotopic map is presumed to precede the development of the orientation map in V1 in primates. Ηij(t) = σ ( ζr1,r2 μij,r1r2 + γE Eij,kl ηkl(t − 1)− γI Iij,kl ηkl(t − 1))
