Design and Application of a New Automated Fluidic Visceral Stimulation Device for Human fMRI Studies of Interoception
Mapping the brain centers that mediate the sensory-perceptual processing of visceral afferent signals arising from the body (i.e., interoception) is useful both for characterizing normal brain activity and for understanding clinical disorders related to abnormal processing of visceral sensation such as stress incontinence and gastroesophageal reflux disease. Here, we report a novel closed-system, electrohydrostatically driven master–slave device that was designed and constructed for delivering controlled fluidic stimulations of visceral organs and inner cavities of the human body within the confines of a 3T MRI scanner.
Design and Characterization of an Exoskeleton for Perturbing the Knee During Gait
We aim to probe the neuromechanics underpinning human locomotion. This information can be used to improve our understanding of typical and atypical joint behaviors, and to improve the design and control of gait assistive devices.
