2012.07.20: Tanuj Gulati - Organizational Modularity in Voluntary Frog Behaviors and its Neural Basis

  • Motor primitives are driven by kinetic, kinematic and physiological triggers
  • Do voluntary behaviors of frogs utilize modular EMG?
    • Recorded from decerebrate and intact animals
    • Mouth slams shut when frog muscles jump
    • Use ICA
      • Mixing matrix
      • Activation time series
    • Motor primitives from voluntary movement match motor primitives in spinalized frogs
    • Timing of behavior is slowed in spinalized vs voluntary
    • Leg control appears to be independent during jump as synergies are localized to an individual leg.
  • Neural basis of primitives identified in voluntary behaviors
