All linear values represent mean ±s.e.m. For left and right mastoid stimulation, linear values significantly different from those of the null condition are in italic. Directional data are given as mean angle and its concentration (r) in parentheses (see Statistical methods). Angles that were significantly clustered (non-random in distribution) are in bold type.
