2. How can you calculate a weighted average of directional measures as in Georgopoulous et al?

  • Vector sum of prefered directions weighted by firing rate. Population vector predicts actual movement
  • Firing rate x vector sum of preferred directions weighted by amplitude
  • Firing rate x vector sum of preferred directions weighted by firing rate
  • Vector sum of prefered directions weighted by firing rate. Population vector does not predict actual movement

3. Which is the best known population code?

  • Somatosensory code for touch
  • Hippocampal code for spatial navigation
  • Retinal code for colour
  • Hippocampal code for head orientation

4. Which is the correct process of shape coding in V4?

  • Predictions based on model, matches data? -> Model of single neuron responses -> single neuron responses
  • Model of single neuron responses -> predictions based on model, matches data? -> single neuron responses
  • Single neuron responses -> model of single neuron responses -> predictions based on model, matches data?
  • Model of single neuron responses -> single neuron responses -> predictions based on model, matches data?

5. The preferred value/firing rate of V4 neurons...

  • Varies systematically with the shape and orientation of simple silhouettes
  • Varies systematically with the shape and orientation of global form
  • Varies systematically with the shape and orientation of complex objects
  • Varies systematically with the shape and orientation of object affordances
