Recognition of invariances by cycled neurons

Abstract

Empirical evidences brought by neurosciences prove the neuropsychological basis constructs, namely invariance already claimed by modern linguistics. However, emphasis will be given to the psychological reality of letters’ features invariance, demonstrated by various experiments which had been recently run by neuroscientists. Two types of invariance will be discussed, the spatial and the fonts invariance. A description of invariant features of the Roman alphabet ends the paper.
