Between-subject variability and within-subject reliability of the human eye-movement response to bilateral galvanic (DC) vestibular stimulation.

abstract：:Cortical migration defects are often associated with epilepsy. In mesial temporal lobe epilepsy (MTLE), granule cell dispersion (GCD), a migration defect of dentate granule cells, is frequently observed. Little is known how GCD develops and to which extent it contributes to the development of seizure activity. Since t...
