“…Its initial bilateral phase is followed by the lateralised readiness potential (LRP), which is contralateral to the movement and considered to reflect the output of the response selection stage (Coles, 1989; Eimer, 1998). A consistently negative pre‐central RP can only be registered by age ten (Chiarenza, Papakostopoulos, Giordana, & Guareschi‐Cazzullo, 1983). Recent developmental work combining ERP with fMRI also indicates that the basic motor network is established around age 9, and that topographic changes of motor ERPs beyond this age may result from increasing deactivation of a non‐specific, task‐irrelevant default network with age (Halder et al, in press).…”

“…Neurons in the supplementary eye field of the prefrontal cortex of rhesus monkeys fire more often before subsequent antisaccades than prosaccades Schlag-Rey et al, 1997!, which may be the source of this anticipatory CNV. In contrast to their failure to show an anticipatory CNV in the context of the antisaccade task, 10-to 11-year-old children do show a readiness potential in anticipation of the appearance of a visual target~Chiarenza, Papakostopoulos, Giordana, & Guareschi-Cazzullo, 1983!. Hence, the absence of anticipatory activity appears specific to the antisaccade task.…”

We examined heritability of error rate on the antisaccade task among female twin youths. This task appears to be sensitive to prefrontal functioning, providing a measure of individual differences in inhibitory control associated with genetic risk for schizophrenia. The sample consisted of 674 11-year-olds and 616 17-year-olds, comprising the two cohorts of female twins from the Minnesota Twin Family Study, a population-based investigation of substance abuse and related psychopathology. We used biometric model-fitting methods to determine the relative magnitude of genetic and environmental influences on performance. In both age cohorts, the best fitting model contained additive genes and nonshared environment. Despite substantial age-related differences in mean performance levels (effect size = .81), additive genes accounted for greater than half the variance in performance in both age cohorts. These results are consistent with the hypothesis that antisaccade error rate might serve as an endophenotype for behavior disorders reflecting frontal lobe dysfunction or problems with inhibitory control.

“…The major differences arose from the absence of premotor CNV in young children (6-11 years old) with respect to adolescents (12-18 years old). Previous developmental studies have shown that the Bereitschaftspotential potential (BP), which is a negative potential in adults indexing motor preparation, inverts its polarity from positive to negative in children aging from 6 to 8 years old (Chiarenza et al, 1983). Bender et al (2005) also showed that the auditory sensory component of the CNV would develop earlier than the motor component.…”

Objectives: The present study investigated the influence of the cerebral maturity in the process of cue task-specific preparatory activation induced by an spatial cue using a central cue Posner paradigm. For these purposes, the behavioral responses and the Contingent Negative Variation (CNV) generated between the S1 (the warning stimulus) and the S2 (the imperative stimulus) were compared in 16 healthy children (8-13 years old) and 17 healthy young adults (18-23 years old). Methods:The EEG was recorded from 20 scalp sites of the International 10-20 system. The complete trial period included a central directional cue that was on for 300 ms and an attentive waiting period lasting 1360 ms. Finally, a peripheral target subtending a visual angle of 4.56º and situated 2.28º eccentrically in the horizontal meridian appeared. The early and late components of the CNV appearing in the period between the cue and the target were analyzed. Results:The CNV of children did not show contralateral cortical activation related to motor preparation. However, the young adults showed contralateral to the cue activation in motor areas.The children and young adults showed cortical activation in the posterior sensory areas, displaying a contralateral to the cue pattern of activation. In addition to this, a parietal positive component appeared in children during the CNV period. Conclusions:These results might reflect a higher immaturity of the motor preparation system compared with the sensory preparatory system in children. It is possible that children used different strategies than young adults to prepare for stimuli and responses.
