This chapter explores the epileptic patients with either left (LTL) or right (RTL) temporal lobe lesions as well as normal control subjects (NC) in two different tasks involving the processing of time-related (temporal) information. It also examines the processing of temporal microvariations in music. The results show the specialization of LTL structures in processing rapid sequential auditory information. It also reveals that LTL patients but not RTL were impaired as compared to NC subjects in the increment detection. However, all groups showed differences between the two levels of difficulty, suggesting that top-down processing remains functional. Thus, these findings indicate that LTL structures are predominantly involved in perceiving time-related perturbations in familiar tunes as well as in isochronous sequences, extending to the musical domain findings previously reported in speech.

Keywords:   cerebral substrates, musical temporal process, temporal microvariations, music, left temporal lobe, right temporal lobe, familiar tunes, isochronous sequences
