      asymmetry of the visual evoked cortical response.
PG  - 257-61
AB  - Visual evoked cortical responses (VECRs) were recorded from the left (O1) and 
      right (02) hemispheres at varying interstimulus intervals (ISIs) in children who 
      were either: Normal (dextral), Dextral Retardates, or Sinistral Retardates. 
      Latencies of N1 and P2 components of the VECR were stable and similar for both 
      hemispheres in all groups. There was an asymmetry between the hemispheres for 
      N1-P2 amplitude: right greater than left in Normals; this direction of asymmetry 
      was also present in Sinistral Retardates, but was reversed in Dextral Retardates. 
      The direction of normal VECR asymmetry was the reverse of that previously 
      established for the auditory evoked cortical response (AECR) amplitude (Richlin, 
      et al., 1973; Matsumiya, et al., 1972; Morrell & Salamy, 1971; Wood, et al., 
      1971). It is suggested that some neural mechanism of the retardates may allow 
      excessive non-verbal stimulation of the normally "verbal" hemisphere. The 
      electrical activity of the brain consequent to auditory or visual stimulation 
      appears to depend upon: the modality of stimulation, the mental status of the 
      individual, and his handedness. These factors have led to the establishment of an 
      additional index to provide differential diagnosis of the mental status of the 
      child.
