Determinative factors in human tonotopy: tentative analysis.
Two main parameters of stimulation were checked as an attempt to investigate the limits of the tonotopic organization in the human auditory cortex. Auditory Evoked magnetic Field (AEF) experiments from a dozen normal subjects are reported. Five of them clearly showed tonotopic AEF responses to long tone bursts stimuli, which disappeared when equivalent white noise was superimposed to the tone. Discrepancies from previous reports and high inter-individual variability are discussed.
