As well as neuro-anatomic and behavioural studies aimed at elucidating the biological bases of dyslexia, in recent years there has been increasing interest in functional brain studies of reading and reading disability (see Pugh et al., 2000a). Neuro-imaging studies of dyslexia extend previous electroencephalographic (EEG) and evoked potential (EP) investigations (largely of cerebral laterality differences between good and poor readers) and link with imaging studies of auditory and visual verbal processing in normal readers. Readers interested in early EEG studies may wish to consult the paper by Duffy and McAnulty (1985) and for more recent work papers by Ackerman, McPherson, Oglesby, and Dykman (1998), Rippon and Brunswick (2000) and Leisman (2002).
