Response Selection
How do we plan movements of our eyes, arms or feet towards targets of interest? How do the processes of target selection and response selection interact? What is the substrate for eye-hand coordination?

Bimanual and Eye-Hand Coordination
How do we coordinate our two arms and eyes?

Spatial Signals
How is spatial information encoded, stored and transformed in the brain?

Decision Making
How do neurons make stimulus discriminations?

Task Representations
We can switch rapidly between different tasks, though a task such as task-switching carries a price. Do monkeys show comparable behavior? How are tasks represented, and how is task switching implemented?

Vestibular System
The vestibulo-ocular reflex (VOR) is an excellent model system for studying spatial representations and sensory to motor transformations.

Monkey fMRI and Polarography
Functional MRI using monkey subjects
