Neural Coordination Dynamics

Theoretical and empirical investigations, using simple yet powerful paradigms and the concepts and tools of non-linear dynamics, have established that emergence of patterns of coordinated actions in humans is governed by principles of self-organization. Research in HCND lab seeks to uncover the neural curcuitry that contributes to complex behavioral dynamics. In particular we seek the neural mechanisms that specify the spatiotemporal order among multiple interacting sensory and motor components and that allow ongoing behavioral patterns to flexibly adjust in response to changing task and environmental conditions.

Neurophysiological Basis of Human Timing

Time is implicit in most human action and cognition. Work in HCND parallels a growing interest in cognitive neuroscience to uncover the neural basis of time perception and production within the millisecond to second range. A theoretically important question we address is whether temporal processing is subserved by specialized neural systems or whether time information is an emergent property of neural activity and cognitive processing. A number of experimental settings are exploited to address this overarching issue. The experimental approach is to uncover the parameters that critically influence the neural systems recruited for temporal processing. To learn more about this research click here.

 

Neural Basis of Cognitive Deficits Associated with Mild Brain Injury

Together with a national and international team of collaborators, our research seeks to understand the neurophysiological basis of cognitive and behavioral impairment resulting from mild brain injury (MBI). Using concussion as a model system, we investigate the relationship between macroscopic measures of brain function and cognitive/behavioral performance over the temporal progression of the injury.
