Assessing Decision-Making Capacity After Severe Brain Injury, Andrew Peterson
Electronic Thesis and Dissertation Repository
Severe brain injury is a leading cause of death and disability. Following severe brain injury diagnosis is difficult and errors frequently occur. Recent findings in clinical neuroscience may offer a solution. Neuroimaging has been used to detect preserved cognitive function and awareness in some patients clinically diagnosed as being in a vegetative state. Remarkably, neuroimaging has also been used to communicate with some vegetative patients through a series of yes/no questions. Some have speculated that, one day, this method may allow severely brain-injured patients to make medical decisions. Yet, skepticism is rife, due in part to the inherent difficulty of …

Moving along to the beat of music is a universal human trait. It is a behaviour that displays the interaction between auditory and motor systems during beat perception. While several studies demonstrate that motor structures are involved in beat perception, the time course of motor system excitability during beat perception is not well understood. To examine the time course of motor system excitability in beat perception, we stimulated the motor cortex with transcranial magnetic stimulation (TMS) and measured the amplitude of the corresponding motor evoked potentials from the first dorsal interosseous (FDI) muscle while participants listened to rhythms that induced …
