The big picture of motor control
Students will create a large diagram, fully mapping the architecture of human motor control ‐ including sensory receptors, nerve roots and tracts, the spinal cord and brain. The big picture of motor control is worth 15% of your final class grade. Assignment Details Due – 4/14/15
Students must assimilate class information as well as use background reading to put together a single diagram mapping the way that a specific motor skill is controlled. Students will first select a discrete skill. This must be approved before continuing. The diagram can be hand drawn or created in a computer program (e.g., PowerPoint). You will need to make several rough drafts to plan this out correctly.
The diagram must contain the following elements (you may include other elements but it is not required) :
1. All involved proprioceptors
2. Dermatomes and afferent pathways and tracts in the spinal cord
3. Myotomes and efferent pathways and tracts in the spinal cord
4. The somatosensory cortex
5. The prefrontal cortex
6. The motor cortex and premotor cortex
7. The basal ganglia
8. The cerebellum
The diagram must show all relevant connections between working parts (including an indication of direction of flow of neural information). You should annotate the diagram to indicate the purpose of the key components in the system.Rubric
Point Value Completeness of elements
‐ Are all key elements in the system included?
30%Connections between elements
‐ Are the elements in the system connected correctly?
‐ Is the direction of the connection clear?
30%Lay out of the diagram
‐ Is the diagram sensibly arranged so that it is clear and easy to follow?
Annotations to explain roles of elements in the system ‐ Are the key elements annotated to explain their role?
