Quantitative electroencephalographic validation of left and right temporal lobe signs and indicators in normal people.

During a single 20-min. exposure to partial sensory deprivation, the average duration of alpha rhythms over the left temporal lobe (T3) increased significantly compared to that for the right homologous region (T4). The percentage changes (increase) over time in the duration of alpha rhythms over the left temporal lobe but not the right temporal lobe were significantly correlated (.64) with histories of automatic behaviors (cessation of awareness) while only the relative increases over time in the durations of alpha rhythms over the right temporal lobe were correlated with histories of vestibular-auditory experiences (.42). The results suggest construct validity for differential hemispheric sources of some specific clusters of complex partial epileptic-like experiences that have been inferred to reflect the continuum of temporal lobe lability.
