The grapheme (text) to phoneme (sound) conversion
involves both fast and slow routes functioning parallel
while reading meaningful words. Lexical decisions to
pseudowords proceeds slowly and exhaustively than that
to words. Neural processing while reading pseudowords
involves successful mapping of orthographic forms that
recruits inferior frontal gyrus (BA44 and 45), insula,
thalamus and caudate nucleus. The current study not only
documents the role of these areas but also provides
evidence that the need for exhaustive search of mental
lexicon during pseudoword reading does not affect the
reaction time supersedes the slow.
