description: |
  Non-invasive recordings of gross neural activity in humans often show responses 
  to omitted stimuli in steady trains of identical stimuli. This has been taken 
  as evidence for the neural coding of prediction or prediction error. However, 
  evidence for such omission responses from invasive recordings of cellular-scale 
  responses in animal models is scarce. Here, we sought to characterise omission 
  responses using extracellular recordings in the auditory cortex of anaesthetised 
  rats. We profiled omission responses across local field potentials (LFP), analogue 
  multiunit activity (AMUA), and single/multi-unit spiking activity, using stimuli 
  that were fixed-rate trains of acoustic noise bursts where 5% of bursts were randomly 
  omitted. Significant omission responses were observed in LFP and AMUA signals, but 
  not in spiking activity. These omission responses had a lower amplitude and longer 
  latency than burst-evoked sensory responses, and omission response amplitude increased 
  as a function of the number of preceding bursts. Together, our findings show that 
  omission responses are most robustly observed in LFP and AMUA signals (relative to 
  spiking activity) but do not show evidence for low-frequency phase locking. This has 
  implications for models of cortical processing that require many neurons to encode 
  prediction error in their spike output.
