Each neuron in the primary motor cortex (M1) is like a musician in an orchestra, contributing to a larger harmony under the constraint of a “neural manifold”—a geometric score describing the correlated signals produced by the neural musicians that drive movement. Despite the widespread recognition of the importance of M1...
Ankle sprains are the most common musculoskeletal injury. After an ankle sprain, about 40% of individuals develop Chronic Ankle Instability (CAI), resulting in recurrent sprains, the ankle giving way, or feelings of instability. Most sprains occur due to excess inversion of the ankle. Frontal-plane ankle stiffness quantifies the ankle’s ability...
Stairs and curbs often present as an exhausting environmental barrier for individuals with bilateral cerebral palsy (CP) due to their lower limb motor impairments. Indeed, performance in stair-climbing in this population has a higher correlation with disruption of mobility than walking. Community members affected by CP consider impaired mobility a...
The physical structure of chromatin has recently emerged as a key contributor to genome regulation and cellular function. Chromatin packing dictates the conformation of the 2-meter-long DNA polymer within the ~10 μm cell nucleus. This conformation can influence gene function by regulating the accessibility of molecular regulators to DNA, altering...
Bio-integrated electronics with advanced monitoring capabilities have garnered considerable interest as a means of expanding patient care beyond traditional hospital and clinic settings. These mechanically soft microsystems, many of which are bioresorbable and wireless, have the potential to replace bulky, rigid, and wired medical technologies by matching or exceeding their...
Nucleic acid therapeutics can be drug molecules with high programmability, minimal off-target effects, and the capability to address “undruggable” targets for diseases. In addition, each time a new drug is needed, one needs to only change the sequence as opposed to finding an entirely new structure. One nucleic acid type...
Wireless power strategies are critical to system level implementation of bio-integrated devices. To achieve mechanically robust, manufacturable systems, batteries are often integrated as an on-board power source to support sensing, wireless communication and signal conditioning. Unfortunately, most sources of battery power use hazardous and environmentally harmful materials, which frustrate incorporation...
Cancer has long been the second-leading cause of death in the United States and represents the leading cause of death in midlife (age 40-60). While the prognosis for many cancers has vastly improved over the last thirty years, many cancers remain elusive due to the late-onset of symptoms, the specific...
Chromatin is the biological material that packages our genetic information. In humans, 2 meters of linear DNA is compacted into an approximately 6 μm nucleus. Our DNA is transcribed into RNA, which is then translated into proteins. Cellular phenotype, the composite of all cellular functions, is defined by the entire...
The current view in neuroscience holds that the brain, together with its sensory and motor structures and the environment, form a closed-loop system – a sensorimotor loop – in which the brain receives information from the environment and converts it into a motor response while simultaneously making predictions about future...
