6 - Sensorimotor transformation
Topics addressed in this lecture
- Neural Information flow for movement generation
- Cortical areas related to action
- Movement representations in the primary motor and parietal cortex
- Instructed delay task for neural testing
Example for questions you should be able to answer
- Describe the efferent and afferent information flow for planning and executing a reach-out and grasp movement
- How are neurons in primary motor cortex tuned in a center-out reaching task? How does decoding with the population vector method work?
- Describe an experiment to determine the coordinate frame in which reach movements are represented in the parietal cortex
Important concepts
- Sensorimotor transformation
- Coordinate frames and coordinate transformations
- Neural tuning specific for action type and movement direction
- Gain modulation of tuned neural activity
