Contribution of cerebellar loops to action timing
Abstract
Recent studies of sensorimotor processing have benefited from decision-making paradigms
that emphasize the selection of appropriate movements. Selecting when to make those
responses, or action timing, is important as well. Although the cerebellum is commonly
viewed as a controller of movement dynamics, its role in action timing is also firmly
supported. Several lines of research have now extended this idea. Anatomical findings
have revealed connections between the cerebellum and broader timing circuits, neurophysiological
results have suggested mechanisms for timing within its microcircuitry, and theoretical
work has indicated how temporal signals are processed through it and decoded by its
targets. These developments are inspiring renewed studies of the role of the cerebellar
loops in action timing.

We study circuits for cognition. Using a combination of neurophysiology and biomedical
engineering, we focus on the interaction between brain areas during visual perception,
decision-making, and motor planning. Specific projects include the role of frontal
cortex in metacognition, the role of cerebellar-frontal circuits in action timing,
the neural basis of "good enough" decision-making (satisficing), and the neural mechanisms
of transcranial magnetic stimulation (TMS).
