متن کاملExcitability Change in the Ipsilateral Primary Motor Cortex during a Unilateral Rhythmic Contraction of Finger Muscles : a Neurophysiological Study Using Transcranial Magnetic Stimulation
Recent transcranial magnetic stimulation (TMS) and functional magnetic resonance imaging (fMRI) studies in human demonstrated that while performing a unilateral movement, activity of primary motor cortex (M1) ipsilateral to the movement side contributes to motor performance. been well known that the modulations of ipsilateral M1 (ipsi-M1) excitability are dependent on type of motor task and dif...
متن کاملRole of the ipsilateral motor cortex in mirror movements.
The mechanism of mirror movements in two patients was investigated; one with congenital mirror movement, the other with schizencephaly. Transcranial magnetic stimulation on one side elicited motor evoked potentials (MEPs) in their thenar muscles on both sides with almost the same latencies, minimal thresholds, and cortical topographies. During voluntary contraction of the thenar muscle on one s...
متن کاملChange in the Ipsilateral Motor Cortex Excitability Is Independent from a Muscle Contraction Phase during Unilateral Repetitive Isometric Contractions
The aim of this study was to investigate the difference in a muscle contraction phase dependence between ipsilateral (ipsi)- and contralateral (contra)-primary motor cortex (M1) excitability during repetitive isometric contractions of unilateral index finger abduction using a transcranial magnetic stimulation (TMS) technique. Ten healthy right-handed subjects participated in this study. We inst...
متن کاملEvidence from human scalp electroencephalograms of global chaotic itinerancy.
My objective of this study was to find evidence of chaotic itinerancy in human brains by means of noninvasive recording of the electroencephalogram (EEG) from the scalp of normal subjects. My premise was that chaotic itinerancy occurs in sequences of cortical states marked by state transitions that appear as temporal discontinuities in neural activity patterns. I based my study on unprecedented...
