- Gary Paige - Spatial localization
- Vision - visual reference frame
- Audition - head reference frame
- What about visual/hand reference frame?
- Auditory spatial localization is aligned to gaze
- Gdowski - Postural reflexes - reweighting due to changes in inertia (head rotation)
- Reflexes adapt to changes in inertia to maintain kinematics
- Paul DiZio - Development of context specific adaptation to limb and object dynamics in human arm kinematics
- Coriolis vs robot curl - give self vs environment context
- No context change for kids under six years old
- Context appears to be based on experience
- Lackner - Rotating rooms
- Arguing for large feedforward component
- Likely large mismatch between golg tendon organ and muscle spindle feedback during coriolis forces
- Dan Marigold - Visual input regarding the environment critical for movement
- Variability decreases right before obstacle
- You need to get the body into a functional configuration, right?
- How about bowling, long jump, diving board?
- Gaze fixation occurs before reaching obstacle
- Did not readjust gaze
- Plane of head for two steps ahead does it correspond to keeping head in position for semicircular canals to be level?
- Trevor Drew - Posterior parietal cortex in controlling precise walking in cats
- Planning
- Posterior parietal cortex, premotor cortex, basal ganglia, lateral cerebellum
- Lesion causes cats to hit the obstacle
- Process visual information to adjust gains necessary for paw placement
- Keir Pearson - Memory in motor movements
- Cats remember obstacles
- Parietal lesion destroys long lasting memory
- OBstacle is represented relative to the cat's body
- Amy Bastian - Learning and context
- Visual context makes a difference (more transfer w/ eyes closed)
- Timing and spatial adaptation appear to occur at different rates
- Seems that adaptation occurs mostly with the spatial characteristics.
