  1. In silent neurons long-lasting depolarization (for a period of 20 s after the stimulus) greater than 2 mV was scored as a response.
  2. In spontaneously active neurons average changes (for a period of 20 s after the stimulus) in frequency more than 20% relative the prestimulus level were scored as a response.
