Effects of short-latency afferent inhibition on short-interval intracortical inhibition.
Peripheral nerve stimulation inhibits the motor cortex, and the process has been termed short-latency afferent inhibition (SAI) at interstimulus intervals (ISIs) of ∼20 ms. The objective of the present study was to test how SAI interacts with short-interval intracortical inhibition (SICI) under different stimulation conditions. We studied 20 healthy volunteers. Surface electromyogram was record...

24 Peripheral nerve stimulation inhibits the motor cortex and the process has been termed 25 short latency afferent inhibition (SAI) at interstimulus intervals (ISI) of ~20 ms. The 26 objective of the present study is to test how SAI interacts with short interval intracortical 27 inhibition (SICI) under different stimulation conditions. We studied 20 healthy 28 volunteers. Surface electromyogra...
متن کاملConditioning intensity-dependent interaction between short-latency interhemispheric inhibition and short-latency afferent inhibition.
The relationship between sensory and transcallosal inputs into the motor cortex may be important in motor performance, but it has not been well studied, especially in humans. The aim of this study was to reveal this relationship by investigating the interaction between short-latency interhemispheric inhibition (SIHI) and short-latency afferent inhibition (SAI) in humans with transcranial magnet...
متن کاملShort-latency afferent inhibition determined by the sensory afferent volley.
Short-latency afferent inhibition (SAI) is characterized by the suppression of the transcranial magnetic stimulation motor evoked potential (MEP) by the cortical arrival of a somatosensory afferent volley. It remains unknown whether the magnitude of SAI reflects changes in the sensory afferent volley, similar to that observed for somatosensory evoked potentials (SEPs). The present study investi...
متن کاملShort and long latency afferent inhibition in Parkinson's disease.
Sensory abnormalities have been reported in Parkinson's disease and may contribute to the motor deficits. Peripheral sensory stimulation inhibits the motor cortex, and the effects depend on the interstimulus interval (ISI) between the sensory stimulus and transcranial magnetic stimulation (TMS) to the motor cortex. Short latency afferent inhibition (SAI) occurs at an ISI of approximately 20 ms,...
