Research Interests

Dr. Andreatta is director of the Laboratory of Speech-Orofacial Sensorimotor Physiology at the University of Kentucky. His principal area of research focuses on how the CNS functionally gates somatosensory input (tactile and proprioceptive) and influences motor performance and perception in the lower face during static and dynamic skilled orofacial tasks. Other research interests include orofacial force dynamics, laryngeal neurophysiology, aerodynamic assessment of the vocal tract, and sensory psychophysics and physiology.

Current studies couple psychophysical and force control strategies to explore how the perceptual detection of somatosensation delivered to the orofacial area is altered during the performance of visually-guided and skilled oromotor behaviors. This paradigm provides a means for examining how the cognitive appreciation of somatosensory input is altered in the behavioral context of orofacial fine-force regulation. Also used in the lab are standard EMG techniques and stimulus-evoked reflex analyses to investigate the central modulation of lower facial motoneuron populations during skilled and dynamic activity in the orofacial neuromuscular system.
