Clinical Trial
Effect of theta burst stimulation over the human sensorimotor cortex on motor and somatosensory evoked potentials.
To study the after-effect of theta burst stimulation (TBS) over the left sensorimotor cortex on the size of somatosensory as well as motor evoked potentials evoked from both hemispheres in healthy human subjects. ⋯ TBS is an interventional tool that can induce rapid reorganization within cortical somatosensory as well as motor networks in humans.

Randomized Controlled Trial
The after-effect of human theta burst stimulation is NMDA receptor dependent.
To provide pharmacological evidence that the after-effects of theta burst stimulation (TBS) involve plasticity like changes in cortical synaptic connections, using the N-methyl-D-aspartate receptor antagonist memantine. ⋯ The NMDA dependency of the after-effects of TBS adds to the understanding of the underlying mechanism of TBS, and suggests that these after-effects are likely to involve plasticity like changes at synaptic connections in motor cortex.

Randomized Controlled Trial
Effect of low-level clenching and subsequent muscle pain on exteroceptive suppression and resting muscle activity in human jaw muscles.
To investigate the effects of muscle fatigue induced by low-level isometric jaw-clenching and subsequent glutamate-evoked muscle pain on the exteroceptive suppression (ES) response and resting electromyographic (EMG) activities in human jaw muscles. ⋯ Muscle fatigue which can be observed in patients with oral dysfunctions may interact with nociceptive regulation and influence the clinical presentation of jaw symptoms and function.

To investigate the possible presence of multiple spino-thalamic pathways with different conduction velocities (CVs) in the human spinal cord. ⋯ Both the N1 and P2 potentials should be recorded in the clinical routine since a dissociated abnormality of either response may be found in lesions of the nociceptive system not only in the brain, but also at spinal cord level.
