“…Supporting this, ERP components (both amplitude and latency) were not different between eyes-open and eyes-closed conditions in an auditory discrimination task (Polich, 1986). The eyes-closed procedure has frequently been employed in other finger tapping studies (Knyazeva et al, 1997;Sammler et al, 2007) because it minimizes focal changes associated with visual input (e.g., participants were prone to observe their finger movements) which could be incorrectly associated with the processing of auditory stimuli (Barry et al, 2007). Furthermore, because the potential alpha activity would always be present across our experimental conditions, it would be canceled out in our condition-wise comparisons.…”

Contingent negative variation (CNV) associated with sensorimotor timing error correction

Introduction: Detection and subsequent correction of sensorimotor timing errors is fundamental to adaptive behavior. Using scalp-recorded event-related potentials (ERPs), we sought to find ERP components that are predictive of error correction performance during rhythmic movements.Method: Healthy right-handed participants were asked to synchronize their finger taps to a regular tone sequence (every 600 ms), whilst EEG data were continuously recorded. Data from 15 participants were analyzed. Occasional irregularities were built into stimulus presentation timing: 90 ms before (advances: negative shift) or after (delays: positive shift) the expected time point. A tapping condition alternated with a listening condition in which identical stimulus sequence was presented but participants did not tap.Results: Behavioral error correction was observed immediately following a shift, with a degree of over-correction with positive shifts. Our stimulus-locked ERP data analysis revealed, 1) increased auditory N1 amplitude for the positive shift condition and decreased auditory N1 modulation for the negative shift condition; and 2) a second enhanced negativity (N2) in the tapping positive condition, compared with the tapping negative condition. In response-locked epochs, we observed a CNV (contingent negative variation)-like negativity with earlier latency in the tapping negative condition compared with the tapping positive condition. This CNV-like negativity peaked at around the onset of subsequent tapping, with the earlier the peak, the better the error correction performance with the negative shifts while the later the peak, the better the error correction performance with the positive shifts.Discussion: This study showed that the CNV-like negativity was associated with the error correction performance during our sensorimotor synchronization study. Auditory N1 and N2 were differentially involved in negative vs. positive error correction. However, we did not find 3 evidence for their involvement in behavioral error correction. Overall, our study provides the basis from which further research on the role of the CNV in perceptual and motor timing can be developed.

“…The presence of mirror overflow movements in adolescents and adults in disorders of both the motor cortex and the corpus callosum suggests that the ability to perform unilateral fine motor movements is dependent upon intact interhemispheric and corticospinal connections (Nass 1985;Knyazeva et al 1997;Meyer et al 1998). The supplementary motor complex (SMC) (and in particular the pre-SMC) has dense callosal and interhemispheric connectivity, arguing for a role in voluntary and involuntary movements.…”

Behavioral Neuroscience of Attention Deficit Hyperactivity Disorder and Its Treatment

The use of quantitative neuroimaging (volumetry), motor, and oculomotor assessments for studying children with attention-deficit/hyperactivity disorder (ADHD) has grown dramatically in the past 20 years. Most evidence to date suggests that anomalous basal ganglia development plays an important role in early manifestation of ADHD; however, widespread cerebellar and cortical delays are also observed and are associated with the behavioral (cognitive, motor, oculomotor) phenotype in children with ADHD. These motor and "executive" control systems appear to develop in parallel, such that both systems display a similar protracted developmental trajectory, with periods of rapid growth in elementary years and continued maturation into young adulthood. Development of each system is dependent on the functional integrity and maturation of related brain regions, suggesting a shared neural circuitry that includes frontostriatal systems and the cerebellum (i.e., those identified as anomalous in studies of volumetry in ADHD). Motor and oculomotor paradigms provide unique opportunities to examine executive control processes that exist at the interface between movement and cognition in children with ADHD, also linking cognition and neurological development. The observed pattern of volumetric differences, together with the known parallel development of motor and executive control systems, appears to predict motor and oculomotor anomalies in ADHD, which are highly relevant, yet commonly overlooked in clinical settings.

“…5,36 Therefore, both a continuation and a switching task were evaluated using the computer package Rhythm Integrated TM . 37 With the continuation task, children were asked to tap on the mouse button simultaneously with an auditory stimulus, and to continue this tapping 10 seconds after the stimulus stopped. With the switching task, the child was asked to tap along with a computer stimulus that suddenly switched from a low to a high frequency, and vice versa.…”

Objective: Evaluation of the efficacy of Le Bon Départ (LBD) treatment and Sensory Integration (SI) treatment on motor performance of children with developmental coordination disorder. Design: A single subject design with multiple baseline and alternating treatments. Order of treatment and length of phase were randomized. Measurements were blinded. Setting: Department of Occupational Therapy at the Academic Hospital Vrije Universiteit Amsterdam, The Netherlands. Subjects: Five boys and one girl with developmental coordination disorder (age: 6.0–8.1 years). Interventions: Baseline condition, Le Bon Départ treatment and Sensory Integration treatment. Main outcome measures: The Movement ABC, Praxis Tests, a rhythm test and visual analogue scales. With the exception of the Praxis Tests, lower scores indicate better performance. Results: During both treatments, the performance on the Movement ABC (x̄ = 7.21) and the scores on the visual analogue scales (x̄ = 46.64) were significantly better than in the baseline (Movement ABCbaseline: x̄ = 17.38; visual analogue scalesbaseline: x̄= 68.18). After treatment 2, performance on the Praxis Tests and scores on the visual analogue scales were significantly better than after treatment 1 (Praxis Tests: 113.54 versus 104.68; visual analogue scales: 34.74 versus 58.54). All six children performed better on the Movement ABC during treatment as compared to the baseline. Le Bon Départ led to significant improvement on all dependent variables, Sensory Integration on the visual analogue scales only. The improvements after Le Bon Départ were larger than the improvements after Sensory Integration treatment. On the rhythm test this difference was significant: LBD led to an improvement of 43.01 points, while the improvement after SI was 17.59 points (p < 0.05). Conclusion: Motor performance of children with developmental coordination disorder improved significantly on all dependent variables after the combination of treatments. Le Bon Départ led to more improvement than Sensory Integration. LBD appears to be a valuable treatment method for children with developmental coordination disorder.
