“…In this condition, PDR patients (dominated by left hemisphere disease) showed more activation of the dorsal stream (including the right posterior parietal cortex) compared to PDL patient (dominated by right hemisphere disease). These results point at consistency with previously described right-hemisphere dominance concerning visuomotor transformations [12], [104], including gait [105] and optic flow-derived visuospatial perception in PD [16]. Furthermore, they fit well with a previously suggested relation between left symptomatic PD and freezing of gait occurrence [106].…”

Parkinson-Related Changes of Activation in Visuomotor Brain Regions during Perceived Forward Self-Motion

Radial expanding optic flow is a visual consequence of forward locomotion. Presented on screen, it generates illusionary forward self-motion, pointing at a close vision-gait interrelation. As particularly parkinsonian gait is vulnerable to external stimuli, effects of optic flow on motor-related cerebral circuitry were explored with functional magnetic resonance imaging in healthy controls (HC) and patients with Parkinson’s disease (PD). Fifteen HC and 22 PD patients, of which 7 experienced freezing of gait (FOG), watched wide-field flow, interruptions by narrowing or deceleration and equivalent control conditions with static dots. Statistical parametric mapping revealed that wide-field flow interruption evoked activation of the (pre-)supplementary motor area (SMA) in HC, which was decreased in PD. During wide-field flow, dorsal occipito-parietal activations were reduced in PD relative to HC, with stronger functional connectivity between right visual motion area V5, pre-SMA and cerebellum (in PD without FOG). Non-specific ‘changes’ in stimulus patterns activated dorsolateral fronto-parietal regions and the fusiform gyrus. This attention-associated network was stronger activated in HC than in PD. PD patients thus appeared compromised in recruiting medial frontal regions facilitating internally generated virtual locomotion when visual motion support falls away. Reduced dorsal visual and parietal activations during wide-field optic flow in PD were explained by impaired feedforward visual and visuomotor processing within a magnocellular (visual motion) functional chain. Compensation of impaired feedforward processing by distant fronto-cerebellar circuitry in PD is consistent with motor responses to visual motion stimuli being either too strong or too weak. The ‘change’-related activations pointed at covert (stimulus-driven) attention.

“…The right DLPFC lies within the territory of the right MCA; therefore, we conclude that results of this fTCD study, namely LI to the right during planning, fit nicely with those presented by Unterrainer et al [3]. Woolley et al [22] observed more activation in the right than in the left hemisphere when online visuospatial information was used to control and correct ongoing movements. Although SOC is not a pure motor task, planning ahead may be regarded as preparation to orderly control appropriate movements.…”

Background: Mental planning and carrying out a plan provoke specific cerebral hemodynamic responses. Gender aspects of hemispheric laterality using rapid cerebral hemodynamics have not been reported. Method: Here, we applied functional transcranial Doppler sonography to examine lateralization of cerebral hemodynamics of the middle cerebral arteries of 28 subjects (14 women and 14 men) performing a standard planning task. There were easy and difficult problems, and mental planning without motor activity was separated from movement execution. Results: Difficult mental planning elicited lateralization to the right hemisphere after 2 or more seconds, a feature that was not observed during movement execution. In females, there was a dominance to the left hemisphere during movement execution. Optimized problem solving yielded an increased laterality change to the right during mental planning. Conclusions: Gender-related hemispheric dominance appears to be condition-dependent, and change of laterality to the right may play a role in optimized performance. Results are of relevance when considering laterality from a perspective of performance enhancement of higher cognitive functions, and also of psychiatric disorders with cognitive dysfunctions and abnormal lateralization patterns such as schizophrenia.

“…Probably this model requires more visuospa tial and attentional requirements that are predomi nantly functions of the left hemisphere, and this, per haps, may explain why model 5 is appropriated more by the subdominant arm. Also Woolley and coworkers [58] found that task performance with visual guidance mainly engaged a right lateralized occipital tempo ral parietal network, which may support our discus sion. The fact that the maximum accuracy of motion is provided by model 5, suggests that probably an important condition of precise movement is sufficient reaction time coupled with effective mobilization of the muscular system to implement this motion even though the motion itself has short movement time and a high level of variability error [40].…”

Reaction time and movement duration influence on end point accuracy in a fast reaching task

In labor and sport physiology a great deal of interest concerns the conceptual model of governance of both rapid and precise target directed movements. Widely known in the theory of motor control, Fitts' par adigm determines the time of motion, calculated from the distance to the target and the diameter of the tar get. However this paradigm does not take into account the time of preparation for movement, which can have a significant impact on accuracy. In addition, the literature highlights little evidence of temporal and spatial asymmetry in the production of fast and accurate movements. The aim of our work was to investigate the influence of the duration of the preparatory phase (reaction time -T R ) and duration of protractile motion of the arm (T M ) on the speed and accuracy of movement. Also, the indi vidual asymmetry of the temporal characteristics and accuracy of performance of movements were studied. We measured three aspects of translational motion of the arm to the computerized target: reaction time (T R , s), time of motion of the arm (T M , s), and error in the achievement of the target (ΔL, mm). The group of partic ipants consisted of 12 healthy, right handed, untrained girls, each of whom completed 5 series of 10 discrete movements by each of the left and right arms. Mathematical analysis of the results revealed the existence of five models of performance. Each model was represented in the participant's performance with different probability. The combination of high speed and high precision when the arm moved towards the target was found only in model 5, which combines a long period of preparation for the movement (T R ) and a short time of motion (T M ). The probability of its occur rence in the untrained subjects was very low (2-3%). We suggest that it may be possible to develop special methods of training, geared towards the ability to increase the probability of appearance of this model. Asymmetry of motor action appeared clearly evident only in the parameter of accuracy (right arm committed the least errors), especially when the reaction time (T R ) and movement time (T M ) were close to average values of the sample. This result enables us to recommend this method for the determination of "handedness". The results allow us to conclude that in the process of development of new motor skills which include both precise and rapid movements we must take into account the initial values of reaction time. We also think that Fitts' existing formula should be modified by including the parameter of reaction time.
