Cortex; a journal devoted to the study of the nervous system and behavior

The purpose of the present experiment was to study whether a unilateral cerebral lesion modifies pain parameters with respect to a control group. Electric stimuli were applied to brain damaged patients on the forearm ipsilateral to the lesion, and to both forearms of a control group. ⋯ In the latter group, pain endurance was not significantly different from controls, although there was a tendency towards its decrease. Result are discussed in relation to the problem of the hemispheric specialization for emotional processes.
