Abstract

Abstract

En 中文
Under shift, caused for example by eye movement, or by relative movement of the subject or object of perception, the cortical representation undergoes very large changes in size and shape. Space-variance of cortical representation rules out models that fundamentally require linear interpolation between shifted patterns (e.g., Edelman's model) or rigid shift of an invariant retinal stimulus corresponding to shift at the cortex (e.g., the shifter theory of van Essen). Recently, a computational solution of quasi-shift invariance for space-variant mappings has been constructed (Bonmassar & Schwartz 1997a; 1997b).
