AB  - Individual differences in rats' exploratory behaviour are stable over time, 
      suggesting inherent differences in brain mechanisms for handling sensory 
      information. These differences may have a neurophysiological basis since a 
      negative correlation was found between individual variation in exploratory 
      behaviour and recovery functions of cortical visual evoked potentials. Recovery 
      functions were an expression of the extent to which the visual system recovered 
      its responsiveness following initial stimulation. They were obtained by using 
      pairs of flash stimuli separated by 3 interstimulus intervals (ISIs): 100, 200 
      and 300 msec. Recovery was defined as the amplitude of the response to the second 
      flash expressed as a proportion of the response to the first flash. Only short 
      latency components of the evoked responses were considered. The mean value for 
      recovery averaged over the three ISIs constituted the recovery function. Only 
      responses recorded when rats were quiet but alert were used for analysis. Evoked 
      potential recovery functions appear to reflect a neurophysiological mechanism 
      underlying the different capacities of individual rats for responding to novelty.
