  • An experimental trial
  • Time
  • How many spikes fired in a given period
  • A spike

2. What tuning can generalise e.g the same neuron can detect a stimulus based on similarity to a prototypical representation?

  • Broad tuning
  • Specific tuning
  • Detector tuning
  • Response tuning

3. Which of these is NOT true of the firing rates of neurons?

  • Represent certainty of processing
  • Be interpreted as the probability the particular stimulus is present
  • Reflect and represent uncertainty
  • Signal a degree of match between input and 'preferred value'

4. What is rate coding?

  • Information about the stimulus or response is carried in the rate at which the cell fires
  • Information about the stimulus or response is carried in the pitch of the action potential
  • Information about the stimulus or response is carried in the precise timing of the individual spikes
  • Information about the stimulus or response is carried in the amplitude of the action potential

5. What is temporal coding?

  • Information about the stimulus or response is carried in the amplitude of the action potential
  • Information about the stimulus or response is carried in the pitch of the action potential
  • Information about the stimulus or response is carried in the precise timing of the individual spikes
  • Information about the stimulus or response is carried in the rate at which the cell fires
