title: [Somatosensory chronotopography: normative data].
abstract: Somatosensory chronotopography of a limited number of components gives a simple representation of the potential distribution of evoked potentials over the skull. Components of individual somatosensory evoked potentials over 16 equally distributed electrodes were analysed in 10 healthy volunteers. The distribution of some specific and non-specific components, as found near the somatosensory cortex is defined and the distribution in relation to the individual traces plotted, resulting in seven normative topogramms with 90% appearance area of maxima of the seven different components. Dipoles are often present.
