In recent years, it has become increasingly clear that both the power and phase of oscillatory brain activity can influence the processing and perception of sensory stimuli. Transcranial alternating current stimulation (tACS) can phase-align and amplify endogenous brain oscillations and has often been used to control and thereby study oscillatory power. Causal investigation of oscillatory phase...

Spinal cord excitability, as assessed by modulation of Hoffmann (H-) reflexes, is reduced with fatiguing isometric contractions. Furthermore, spinal cord excitability is reduced during non-fatiguing arm and leg cycling. Presynaptic inhibition of Ia terminals is believed to contribute to this suppression of spinal cord excitability. Electrical stimulation to cutaneous nerves reduces Ia presynapt...

KEY POINTS Theta-burst stimulation (TBS) applied via transcranial magnetic stimulation is able to modulate human cortical excitability. Here we investigated in a rat model how two different forms of TBS, intermittent (iTBS) and continuous (cTBS), affect sensory responses in rat barrel cortex. We found that iTBS but less cTBS promoted late (>18 ms) sensory response components while not affecting...

Sensory stimulation is intended to enhance the rehabilitative potential of brain-injured individuals in a coma or vegetative state. Protocols may involve stimulation of any or all of the following senses: visual, auditory, olfactory, gustatory, cutaneous and kinesthetic. Protocols may involve stimulation of any or all of the following senses: visual, auditory, olfactory, gustatory, cutaneous, a...

OBJECTIVE In a previous transcranial magnetic stimulation (TMS) study we demonstrated that suprathreshold mesh-glove (MG) whole-hand stimulation elicits lasting changes in motor cortical excitability. Currently, there is no consensus with regard to the optimal parameters for the induction of sensorimotor cortical plasticity using peripheral electrical stimulation. Thus, in the present study we ...

Radiofrequency heat lesioning has been advocated to prolong the duration of therapeutic effect of lumbar sympathetic block in Complex Region Pain Syndrome (CRPS) of the lower extremity. Prior to radiofrequency lesioning of the lumbar sympathetic trunk, sensory and motor stimulation may be used to verify that the active needle tip is not adjacent to a spinal nerve to avoid unwanted neural injury...

Introduction: Brain injury induced coma is the main cause of hospitalization of patients in the intensive care unit (ICU) and their consequent stressful physiological complications, which can be prevented using sensory stimulation as a therapeutic method. Nevertheless, identifying and using the optimal sensory stimulation program is crucial. Objective: The present study was conducted to de...
