The effect of temporal lobe surgery on electrodermal activity: implications for an organic hypothesis in the aetiology of schizophrenia.
It has recently been suggested that the bilateral asymmetry of electrodermal activity (EDA) reported in schizophrenia may be related to unilateral temporal lobe dysfunction. To test this hypothesis, 3 aspects of EDA--skin conductance level (SCL), number of spontaneous fluctuations (SF), and skin conductance response (SCR)--were measured bilaterally in 10 patients who had undergone unilateral temporal lobectomy. No differences could be detected between the operated and non-operated sides within the patient group, nor between the patient and control groups. The implications of these findings are discussed.
