The same group later studied the issue of ipsilateral motor cortex activation during motor imagery purchase cialis super active 20 mg overnight delivery impotence at 52. Yet order 20 mg cialis super active otc erectile dysfunction over 40, the analysis provided convincing data showing that the motor imagery effect occurred in those ipisilateral voxels that were also active during motor performance. This notion receives further support from studies that have found a similar congruence for the activations during executed and imagined movements in Copyright © 2005 CRC Press LLC relation to the somatotopic representation of hand, foot, and tongue movements. Across different but probably comparably sensitive approaches there have also been recent studies that reported negative findings regarding M1 activation during motor imagery. A simple view would conclude that some experiments or laboratories simply did not have enough sensi- tivity or power, or that they applied too conservative statistical thresholds to detect effects in M1. This appears rather unlikely because the degree of signal change in those studies that did observe activation in M1, and its relation to the signal change during movement execution, should have been readily detectable by other laborato- ries as well. The opposite approach would be to assume that the cases with positive findings are accounted for by movement execution during (and despite the instruction of) motor imagery. In contrast with the visual system, which can easily be deprived of input, the situation is far more complicated for motor output. There is continuous output, and imagery easily elicits electromyographic (EMG) activity above this resting level. Voluntary relaxation, which in itself may activate M1 as discussed above, and suppression of such imagery-induced activity is difficult to achieve and usually requires training. The problem of controlling for involuntary movement during imagery has been noted by several groups. In that sense, it is doubtful whether the lack of correlation observed with the fMRI findings is conclusive. It is therefore not clear to what extent the learned pattern may have progressively decayed during those sessions. In that sense, it is probably fair to say that to date no study that has reported M1 activation during motor imagery has provided sufficient support for the claimed absence of muscular activity during that condition. So far, one of the few studies using on-line EMG recordings during fMRI of motor imagery was that of Hanakawa et al. Instead of quali- tatively mapping activation under different conditions with a somewhat arbitrary threshold, the authors addressed the quantitative relation of activation effects under imagery and execution of movement. They determined areas with movement-pre- dominant activity, imagery-predominant activity, and activity common to both move- ment and imagery modes of performance (movement-and-imagery activity). The movement-predominant activity included the primary sensory and motor areas, the parietal operculum, and the anterior cerebellum, which had little imagery-related activity (–0. Many frontoparietal areas and the posterior cerebellum demonstrated movement-and-imagery activity. Imag- ery-predominant areas included the precentral sulcus at the level of the middle frontal gyrus and the posterior superior parietal cortex/precuneus. One of us used a different approach for dissociating the effects of motor imagery and actual movements during fMRI measurements. Several psychophysical studies117–119 have dem- onstrated that subjects solve this task by imagining their own hand moving from its current position into the stimulus orientation for comparison. This motor imagery task was paired with a task known to evoke visual imagery, in which subjects were presented with typographical characters and asked to quickly report whether they were seeing a canonical letter or its mirror image, regardless of its rotation. Using a fast event-related fMRI protocol, imagery load was parametrically manipulated from trial to trial, while the type of imagery (motor, visual) was blocked across several trials. This experimental design permitted to isolate modulations of neural activity driven by motor imagery, over and above generic imagery- and performance-related effects. In other words, the distribution of neural variance was assessed along multiple dimensions, namely the overall effects of task performance, the specific effects of motor imagery, and the residual trial-by-trial variability in reaction times unaccounted for by the previous factors. With this approach, it was found that portions of posterior parietal and precentral cortex increased their activity as a function of mental rotation only during the motor imagery task. Within these regions, parietal cortex was visually responsive, whereas dorsal precentral cortex was not.
