Testing the Efficacy of Transcranial Magnetic Stimulation (TMS) in Treating Depression in Patients with Cognitive Impairment
… of this study is to (1) examine the efficacy of Transcranial Magnetic Stimulation (TMS) in treating depression among individuals with cognitive impairment and (2) to examine if TMS is capable of facilitating cognitive improvements independent of mood improvements. Mild cognitive impairment (MCI) …

Modulation of corticospinal excitability during arm cycling in humans
… (Zehr et. al 2004). Advanced methods such as transcranial magnetic stimulation (TMS) and transmastoid electrical stimulation were implemented to examine supraspinal and spinal excitability, and bridge the gap between animal and human research. Therefore, this thesis set out to determine …

EXPLORING COVERT MOTOR PROCESSES: BEHAVIORAL INSIGHTS AND INNOVATIVE APPLICATIONS OF TRANSCRANIAL MAGNETIC STIMULATION
… 1 muscle × 1 action (1m1a) approach, in which transcranial magnetic stimulation (TMS) is applied to the motor cortex and motor-evoked potentials (MEPs) are recorded from a single target muscle. While informative, this method reduces complex motor representations to isolated joints …

Minimally invasive neuromodulation using mechanically-sensitive ion channels and magnetically-actuated nanotransducers
… interventions and noninvasive techniques such as transcranial magnetic stimulation (TMS) and transcranial direct current stimulation (tDCS) have limitations in specificity and penetration depth. Deep brain stimulation (DBS), while effective, is invasive and carries surgical risks. This thesis …

Stimulus parameters influencing cortical responses by transcranial magnetic stimulation targeting I-wave dynamics : duration, intensity and interval between interventions
Transcranial magnetic stimulation (TMS) modulates corticomotor excitability and plasticity; however, the magnitude of the effects appears to depend on a range of stimulus parameters. Three possible critical factors of repetitive TMS (rTMS) interventions are the duration of application, the …

Effects of repetitive transcranial magnetic stimulation as a treatment for persistent auditory verbal hallucinations
… for some patients that experience AVHs. Transcranial Magnetic Stimulation (TMS) is a non-invasive brain stimulation that can inhibit cortical activity in brain regions shown to be hyperactive during AVHs. We studied the effectiveness of repetitive TMS (rTMS) as a treatment for persistent …

Movement velocity effect on cortical reorganization and finger function in stroke.
… single-subject cross over design with functional magnetic resonance imaging (fMRI), transcranial magnetic stimulation (TMS), and function tests. Subjects were trained at home, assisted by telerehabilitation devices supervised by a remote physical therapist. Subjects performed 28,800 repetitions of …

Effects of sensorimotor learning on the human mirror neuron system
… effects can be delayed by repetitive theta burst transcranial magnetic stimulation (TMS) of the inferior frontal gyrus, an area homologous with the premotor F5 mirror neuron area in the macaque. In Chapter 5, single-pulse TMS is used to produce motor evoked potentials (MEPs). In an action …

Interaction of voluntary activity and functional electrical stimulation in the upper extremity as a method for short-term alteration of corticospinal excitability and force control
… movement at all. Often, functional electrical stimulation (FES) is applied passively, as a rehabilitative therapy, to stroke subjects who are unable to participate in RMT. The effects of voluntary contraction and FES are not well understood for the upper extremity following a stroke. This …
