The disappearance of CST from the injured motor cortex was confirmed by immunohistochemical assessment of protein kinase C (PKC) γ expression, a marker of the CST, in the cervical cord at 2 weeks after injury.
However, future studies directly comparing performed imagined and perceived imagined tasks are needed to confirm that motor cortex activity is specific to reality monitoring for action memories.
We investigated specimens from lumbar spinal cord, hippocampus, and the motor cortex from 9 patients with pathologically confirmed SALS (age range, 54 82 years; mean, 63.2 years; 6 men and 3 women), 8 control subjects (age range, 50 86 years; mean, 69.5 years; 6 men and 2 women), and 1 patient with ALS associated with a novel VCP mutation.
This is the first study that has attempted to confirm the efficacy of motor cortex stimulation in reducing cortical responses to painful stimuli in migraine patients.
This points to beta phase playing a functional role in this interval rather than beta amplitude, and it implies underlying changes in primary motor cortex connectivity rather than in excitability, as further confirmed by the phase-locking results.
Moreover, the voluntary movement preparation inhibits subjective pain and evoked responses induced by laser stimuli, thus confirming that activation of the motor cortex can reduce the nociceptive cortical recruitment induced by acute painful stimulation [13].
The RFX analyses confirmed that, in contrast to the motor cortex ROIs, the BOLD response in the prefrontal cortex ROIs was significantly larger for incongruent compared to congruent trials (68.4 ± 12.2 AU, t = 5.6, p < 0.00001), indicating that, as might be expected from previous studies, the fMRI BOLD response in the prefrontal cortex increases in task conflict situations [ 20].
However, our results confirm relation between proximity to the motor cortex and a considerably high risk of new postoperative motor deficit.
Experiment 3 confirmed that cerebellar tissue is significantly deeper than primary motor cortex tissue, and we provide a map of scalp-to-target distances.
First, we confirmed the destruction of the CST originating from the injured motor cortex after cortical impact.
