“…This effect has been shown in normal adults (Mangun and Hillyard, 1991, Gomez, et al, 2004and 2008, in normal children (Enns and Brodeur, 1989, Brodeur and Boden 2000, Perchet and Garcia-Larrea, 2000 and in 16 ADHD children (Perchet, 2001). The presentation of valid cues significantly decreases RTs to the incoming targets (benefits), relative to either the invalid or to the no cue and neutral conditions (costs).…”

“…Moreover, an increase of the posterior positive components for invalid condition with respect to valid conditions at the time latency of the P3 component has also been described (Mangun and, Hillyard, 1991;Eimer, 1993). Recently, (Gómez et al, 2008) the P3b effects have been replicated, but an increase of the P3a to invalidly cued targets have also been observed.…”

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.

“…On the other hand, the P3 shows a rather opposite developmental pattern. This potential is also modulated by validity of the cue, showing larger amplitude at invalid compared to valid-cue trials (Bledowski, Prvulovic, Goebel, Zanella, & Linden, 2004;Gómez et al, 2008), and thus has been related to processes of disengagement and reorienting of attention. In our study, modulation of the P3 by the validity of the cue was larger for the youngest group of children.…”

“…On the other hand, modulation of the P3 has been related to stimulus evaluation processes. The higher amplitude of the P3 for invalidly cued trials appears to signal a mismatch between sensory perception and sensory-motor preparation (Digiacomo, Marco-Pallarés, Flores, & Gómez, 2008;Gómez, Flores, Digiacomo, Ledesma, & González-Rosa, 2008). Developmental studies of orienting attention using Posner's cueing paradigm have found that both 6-13 years old children and adults show higher P1 amplitude on validly cued trials, whereas latencies of P3 appeared delayed for children with respect to adults under invalid conditions (Flores, Gómez, & Meneres, 2010;Perchet & García-Larrea, 2000).…”

Electrophysiological correlates of attention networks in childhood and early adulthood

a b s t r a c tAttention has been related to functions of alerting, orienting, and executive control, which are associated with distinct brain networks. This study aimed at understanding the neural mechanisms underlying the development of attention functions during childhood. A total of 46 healthy 4-13-year-old children and 15 adults performed an adapted version of the Attention Network Task (ANT) while brain activation was registered with a high-density EEG system. Performance of the ANT revealed changes in the efficiency of attention networks across ages. While no differences were observed on the alerting score, both orienting and executive attention scores showed a more protracted developmental curve. Further, age-related differences in brain activity were mostly observed in early ERP components. Young children had poorer early processing of warning cues compared to 10-13-year-olds and adults, as shown by an immature auditory-evoked potential complex elicited by warning tones. Also, 4-6-year-olds exhibited a poorer processing of orienting cues as indexed by lack of modulation of the N1. Finally, flanker congruency produced earlier modulation of ERPs amplitude with age. Flanker congruency effects were delayed and more anteriorly distributed for young children, compared to adults who showed a clear modulation of the N2 in fronto-parietal channels. Additionally, interactions among attention networks were examined. Both alerting and orienting conditions modulated the effectiveness of conflict processing by the executive attention network. The Orienting Â Executive networks interactions was only observed after about age 7. Results are informative of the neural correlates of the development of attention networks in childhood.

Cognitive functions can be assessed and followed up over a period of time with cognitive evoked potentials (CEP) P300� In this context, brainstem auditory evoked potentials (BAEP) are most commonly used, but visual evoked potentials (VEP) are utilized as well� The research in this area has demonstrated that these techniques could be used as a supplemental method in diagnostics of numerous diseases such as Alzheimer's disease, mild cognitive impairment, vascular dementia, epilepsy, craniocerebral trauma, Parkinson's disease, multiple sclerosis, and other degenerative diseases� In addition, P300 can also be used as an auxiliary method in the diagnostics of mental disorders conditions such as schizophrenia, panic disorders, narcotic drug addiction, nicotinism, alcoholism, etc� The method assists in monitoring the course of diseases leading to encephalopathy, such as liver and kidney damage and grave anaemia� The advantages of P300 testing are easy application, non-invasiveness, and an unlimited number of potential applications� Moreover, the results obtained with this method are measurable and can be compared�
