        • Backscroll illusion
          • Linking of implied motion to actual motion
    • Lecture 3; Action Perception
      • Why is Action Perception important?

        • Complex social environments
        • Threat detection
        • Alliances
        • Potential mates
        • Fast and automatic; dedicated systems?

        • Hierarchical visual processing
        • Monkey STS; cells code for actions & properties
        • NOT grandmother cells, population coding!!!
        • STS discriminating within variable low-level conditons (useful for identity), still detect actions. Also;
          • View-dependent coding
          • View-independent coding
          • Object-centered coding
          • Represents organisation of neurons

        • Functional specialisation for bodies
        • Areas
          • STS; dynamic actions
          • EBA + FBA; static bodies and body parts
      • Social Information from AP

        • Theory of Mind
        • Perception of mouth movements
        • Perception of hand gestures
          • Sign language and STS
        • 'Emotional body language'
    • Lecture 4; Mirror Neurons
      • What is a mirror neuron?

          • F5
            • Movement of face and sight face movements (ingestive, communicative...)
        • STS? Not yet...
      • Human mirror neurons?
        • If so, should be found in M1
        • TMS experiments
        • MEPs (enhanced during action oservations)
        • However...it is argued humans DONT have m.neurons bc;
