Half of the subjects received C3 training and the other half C4 training, consisting of 20 half-hour sessions. We assessed the eVects of training on lateralized lexical decision in Hebrew. The lateralized lexical decision test reveals an independent contribution of each hemisphere to word recognition (Barnea, Mooshagian, & Zaidel, 2003). Training increased accuracy and sensitivity. It increased left hemisphere (LH) specialization under some conditions but it did not aVect interhemispheric transfer. Training did aVect psycholinguistic processing in the two hemispheres, diVerentially at C3 and C4. Training also increased hemispheric independence. There were surprising sex diVerences in the eVects of training. In boys, C4 training improved LH accuracy, whereas in girls C3 training improved LH accuracy. The results suggest that the lateralized NF protocol activates asymmetric hemispheric control circuits which modify distant hemispheric networks and are organized diVerently in boys and girls.

We constructed a speeded version of the LANT to optimize use in an Event Related Potential (ERP) paradigm. We evaluated the ability of this new test to behaviorally measure LANT attention networks as well as identify corresponding physiological characteristics of these networks. Speeded trial presentation and increased numbers of trials improved sensitivity of behavioral accuracy measures versus the LANT documented in Greene, et al, 2008. The speeded-LANT (sLANT) validly measured executive Conflict and spatial Orienting in behavior, although omitted an estimate of Alerting in favor of increased trial count. The P3 ERP component correlated with behavioral latency and accuracy sLANT performance; differences between ERP components distinguished networks. The scalp distribution of these ERP components lends weight to existing theories of hemispheric and modular attention networks.

The AP ability is assumed to reflect a unique, language-like representation of non-lexical musical notes in memory. The purpose of this study was to examine this assumption by comparing Event Related Potentials (ERP) of musicians with and without AP, to lexical and non-lexical representation of musical material. Subjects were eighteen young adult musicians. Seven were AP and eleven RP. Auditory stimuli, presented through earphones, were piano notes (non-lexical) or a voice saying the note's name (lexical). Visual stimuli, presented on a computer display were note symbols (non-lexical) or letters (lexical). Subjects performed a number of tasks, combining the two modalities (visual and auditory) and stimulus types (lexical and non-lexical), and reaction times CRT), performance accuracy and evoked potentials were recorded. The tasks forced the subjects to transfer mental representations of musical material from one mode to another. Our most important findings were the differences, between groups, in the scalp distribution of P300 amplitudes. We conclude that absolute pitch possessors use the same internal language as relative pitch possessors, when possible, but the distribution of the underlying brain activity is different between AP and RP subjects.

Visually presented stimuli consisted of either digits (lexical) or unfamiliar (non-lexical) characters. The subjects had to indicate whether a probe stimulus was a member of a preceding memorized set, or not. The memorized sets included 1, 2 or 3 items. Performance accuracies were significantly lower and reaction times longer in the dyslexic group. The significant Group x Lexicality interaction demonstrated P3 amplitudes which were smaller to lexical compared to non-lexical stimuli in dyslexics compared to skilled readers. Brain activity in response to the probes was more prominent over the right scalp in dyslexics, in contrast to controls that had left side prominence. The results suggest that dyslexic children relate to the physical features of stimuli as opposed to skilled readers, who rely more on the linguistic features of the stimuli. We suggest that remembering visually presented items in dyslexics involves different cognitive strategies and brain structures compared to skilled readers.

In this study we explore processes of consolidation of memory during awake hours. Since theta oscillations have been shown to play a central role in exchange of information, we hypothesized that elevated theta during awake hours will enhance memory consolidation. We used a neurofeedback protocol, to enhance the relative power of theta or beta oscillations. Participants trained on a tapping task, were divided into three groups: neurofeedback theta; neurofeedback beta; control. We found a significant improvement in performance in the theta group, relative to the beta and control groups, immediately after neurofeedback. Performance was further improved after night sleep in all groups, with a significant advantage favoring the theta group. Theta power during training was correlated with the level of improvement, indicating a clear relationship between memory consolidation, and theta neurofeedback.

Imaging, clinical, and behavioral evidence demonstrate hemispheric asymmetries in these attentional networks. We constructed a lateralized version of the ANT (LANT), with brief targets flashed in one or the other visual hemifield. We also modified the tests by including invalid spatial cues in order to measure the cost component of Orienting. In a series of experiments, we investigated the efficiency of the attention networks separately in each hemisphere. Participants exhibited significant estimates of all networks measured by the LANT, comparable to the ANT. The three networks were represented in each hemisphere separately and were largely comparable across the two hemispheres. We suggest that the LANT is an informative extension of the original ANT, allowing for measurement of the three attention networks in each hemisphere separately.

While sleep provides the most commonly studied framework for such consolidation processes, posttraining modulation of oscillatory brain activity may also impact on plasticity processes. Under the hypothesis that consolidation of motor learning is associated with theta band activity, we used EEG neurofeedback (NFB) to enable participants to selectively increase either theta or beta power in their EEG spectra following the acquisition phase of motor sequence learning. We tested performance on a motor task before and after training, right after the NFB session to assess immediate NFB effects, 1 day after NFB to assess interaction between NFB effects and overnight sleep-dependent stabilization, and 1 week after the initial session, to assess the effects of NFB on long-term stabilization of motor training. We also explored the extent of the influence of singleelectrode NFB on EEG recorded across the scalp. Results revealed a significantly greater improvement in performance immediately after NFB in the theta group than in the beta group. This effect continued for testing up to 1 week following training. Across participants, post-NFB improvement correlated positively with theta/beta ratio change achieved during NFB. Additionally, NFB was found to cause widespread band-power modulation beyond the electrode used for feedback. Thus, upregulating postlearning theta power may yield contributions to the immediate performance and subsequent consolidation of an acquired motor skill.

The ''SMR/Theta'' protocol rewards increasing power in the 12-15 Hz range while reducing or arresting power in 4-8 Hz range, and it has been used to ameliorate Attention Deficit Hyperactivity Disorder. We examined whether SMR/Theta at frontal sites, F3 and F4, affected attention in the two cerebral hemispheres of normal children, and whether training had differential effects on three attentional networks, Conflict, Orienting, and Alerting. These networks were measured using the Attention Network Test (ANT) and a lateralized version of it, the LANT. Ten Israeli girls (ages 11 ± 1.2 years) performed both the ANT and the LANT, before and after 20 half-hour NF sessions. We found that NF sped up performance. In the ANT, training decreased Conflict and increased Orienting and Alerting. There was an effect of training side, showing that NF was consequential. In the LANT, Conflict was unaffected, but NF improved A and it increased Orienting, especially in the left visual field. Training at F3 resulted in a greater change than at F4. We concluded that: (1) NF was effective, (2) the protocol improved all three attention networks indexed by the ANT, but (3) it did not affect C in the LANT, and (4) the effects of NF were not restricted to the hemisphere under the training electrode.

We tested three patients with partial callosal disconnection. Two anterior patients could not correct their errors in a unilateral version of a visuomotor learning task for which they previously exhibited callosal disconnection, whereas, they corrected most of their errors in two visual matching tasks (comparing abstract shapes or faces) that they could transfer between the hemispheres. An opposite pattern emerged in a posterior patient. He could not correct his errors in unilateral versions of the same visual matching tasks, for which he previously exhibited callosal disconnection. However, he corrected most of his errors in the visuomotor learning task he was able to transfer between the hemispheres.
