TI  - Separate mechanisms control spike numbers and inter-spike intervals in transient 
      responses of cat auditory cortex neurons.
PG  - 17-27
AB  - In the anesthetized cat, some cortical auditory neurons discharge a train of up 
      to 5 spikes in response to the onset of a characteristic frequency tone pulse. 
      This report provides the first description of the inter-spike intervals (ISIs) in 
      these responses. The ISIs were typically close to 2.0 ms in length, and, as 
      indexed by the standard deviation of the interval length, were very regular. 
      Except at threshold levels of stimulation, mean ISIs were relatively insensitive 
      to both tone amplitude and repetition rate. This was true even over ranges of 
      those variables that exerted dramatic effects on spike numbers and first spike 
      latency. These data suggest that the relative timing of discharges within the 
      spike burst is controlled by a mechanism which is separable from that which 
      determines the number of spikes in them. The brevity of the ISIs suggest that 
      they may be a means of enhancing the salience of the transient response against a 
      background of spontaneous discharges.
