The neural processes subserving working memory, and brain structures underlying this system, continue to develop during childhood. We investigated the effects of age gender on audiospatial visuospatial memory in a nonclinical sample school-aged children using n-back tasks. results showed that auditory visual performance improves with age, suggesting functional maturation cognitive areas. differences found tasks suggest larger degree immaturity boys than girls at period 6–10 yr. observed...
Using functional magnetic resonance imaging (fMRI), we measured brain activity of human participants while they performed a sentence congruence judgment task in either the visual or auditory modality separately, both modalities simultaneously. Significant performance decrements were observed when attention was divided between two compared with one selectively attended. Compared selective (i.e., single tasking), dual-tasking) did not recruit additional cortical regions, but resulted increased...
Earlier studies on adults have shown that functional connectivity (FC) of brain networks can vary depending the state and cognitive challenge. Network has been investigated quite extensively in children resting state, much less during tasks is largely unexplored between these states. Here we used magnetic resonance imaging independent component analysis to investigate architecture large-scale 16 (aged 7–11 years, 11 males) young 22–29 10 visual working memory tasks. We identified major...
The aim was to study whether there is indication of a dissociation in processing visuospatial and colour information working memory humans. Experimental subjects performed n-back tasks with without distractive stimuli presented the middle delay period specifically affect mnemonic task-related information. In high memory-load condition, visuospatial, but not colour, task selectively disrupted by distractors. When subvocal rehearsal memoranda prevented articulatory suppression; performance...
Analysis of scalar maps obtained by diffusion tensor imaging (DTI) produce valuable information about the microstructure brain white matter. The DTI scanning child populations, compared with adult groups, requires specifically designed data acquisition protocols that take into consideration trade-off between time, strength, number directions, and applied analysis techniques. Furthermore, inadequate normalization images non-robust reconstruction have profound effects on analyses may biased...
