Corticospinal excitability in patients with unilateral sciatica

Neuroscience Letters, 2003
Patients suffering from sciatica may develop altered patterns of corticospinal drive to muscles of the leg. Electromyographic recordings were made bilaterally from tibialis anterior and lateral gastrocnemius muscles during transcranial magnetic stimulation of the motor cortex from nine patients with unilateral sciatica and seven healthy controls.

Speech‐induced changes in corticospinal excitability

Annals of Neurology, 1996
AbstractThe aim of the experiments was to investigate the effects of speech on the excitability of corticospinal pathways to human hand muscles. Single transcranial magnetic stimuli were given randomly over the hand area of either the left or right motor cortex of 10 right‐handed and 3 left‐handed normal volunteers.

Modulation of Corticospinal Excitability with Contralateral Arm Cycling

Neuroscience, 2020
This is the first study to examine the influence of activity in one limb on corticospinal excitability to the contralateral limb during a locomotor output. Corticospinal and spinal excitability to the biceps brachii of the ipsilateral arm were assessed using transcranial magnetic stimulation (TMS) of the motor cortex and transmastoid electrical ...

The Effects of Selective Response Preparation on Corticospinal Excitability

Cortex, 2000
Both motor imagery and selective motor cues enhance performance. Motor cortex is activated during motor imagery. We wanted to learn if selective motor cueing also activates motor cortex.We gave normal right-handed subjects information about which hand to use to respond to an imperative stimulus (selective intention) or where in space an imperative ...

Increased excitability of the human corticospinal system with hyperventilation

Electroencephalography and Clinical Neurophysiology/Electromyography and Motor Control, 1998
Hyperventilation is effective in inducing generalized spike-wave discharges in patients with absence seizures and improves visual function and normalizes visual function in patients with multiple sclerosis. Hyperventilation increases the excitability of cutaneous and motor axons.

Corticospinal excitability following repetitive voluntary movement

Journal of Clinical Neuroscience, 2018
Post-exercise cortical depression (PED) is induced by non-fatiguing finger movement. Because the type of exercise that causes PED remains unclear, we conducted two experiments to clarify which exercise factors induce PED. Fifteen healthy participants performed repetitive abduction movements of the right index finger at 2.0 Hz (simple rhythmic task) and

Aperiodic Brain Activity Modulates Corticospinal Excitability

Neuroscience Bulletin
Brain state-dependent transcranial magnetic stimulation (TMS) synchronizes with instantaneous power and is a novel time-precise neuroregulation approach. The key to this approach is using instantaneous power to reliably estimate specific cortical excitability. However, the specific influence of instantaneous power, particularly aperiodic brain activity,

Propriospinal transmission of part of the corticospinal excitation in humans

Muscle & Nerve, 2002
AbstractIn humans a substantial part of corticospinal excitation to upper limb motoneurons is mediated through cervical premotoneurons located rostral to motoneurons, analogous to the feline system of C3–C4 propriospinal neurons. The indirect (disynaptic) component of the corticospinal command passing through the propriospinal relay may be updated by ...

Dynamic changes in corticospinal excitability during motor imagery

Experimental Brain Research, 1999
We investigated temporal changes in the amplitudes of motor-evoked potentials (MEPs) induced by transcranial magnetic stimulation over the left motor cortex during motor imagery. Nine subjects were instructed to imagine repetitive wrist flexion and extension movements at 1 Hz, in which the flexion timing was cued by a tone signal.
