In a recovery function design, changes were measured in the somatic evoked potential (SEP) to right median nerve (RMN) shocks preceded by stimulation of: the same nerve (RMN-RMN); the left median nerve having primary input to the homologous sensory area in the contralateral hemisphere (LMN-RMN); the right peroneal nerve having primary input to a different region of the same hemisphere (RPN-RMN); and the auditory nerve with primary input to a different sensory modality (AUD-RMN). Eight inter-stimulus intervals ranged from zero (simultaneous) to 2.5 sec. It was assumed that the degree of interaction between evoked potentials would be related to the degree to which common neural structures are activated or modulated in response to the stimuli. Results were: (a) the primary somatosensory response N20-P30 was little influenced by other somatic or auditory stimulation, interaction occurring predominantly in the RMN-RMN condition; (b) with increasing latency, components showed increasing interaction across modalities; (c) preceding homolateral stimulation (RPN-RMN) showed no greater interaction than preceding contralateral stimulation (LMN-RMN); (d) N55-P100 differed from the primary somatosensory response N20-P30 by showing greater interaction with other somatic stimuli; and (e) N140-P190 showed similarly shaped recovery functions across stimulus pairs but significant differences in magnitude of interaction. These results show that components with similar wave form and topographical characteristics can have different neurophysiological properties.
