Neurobiology

I found that when a clawed frog hears conspecific calls made of clicks, peripheral auditory neurons respond with electrical spike pulses time-locked to the clicks (resembling the call they represent), but some higher midbrain neurons give more spikes/click and better-timed spikes only when the click rate is within a specific range.  Preference for click rate possibly underlies the frog’s discrimination of one call from another.
