Special Issue Information

Dear Colleagues,

Since the beginning of the 21st century, the connectome has been used in various medical imaging tasks and electrophysiological applications, propelling research into the era of artificial intelligence. This Special Issue will highlight both clinical needs and technical challenges in medical imaging processing and describe how emerging trends in connectome are addressing these issues. Topics covered will include network architecture, learning, interpretability, uncertainty quantification. We are looking to present studies that are related to digital pathology mainly in the brain, particularly prominent research highlights related to clinical study applications. Artificial intelligence and neural networks are significant procedures that tackle this kind of medical diagnosis issue. Moreover, medical imaging processing presents a unique challenge that confronts other connected approaches such as deep learning and different machine learning techniques, which are employed in a variety of tasks along with the different medical image modalities. Disease prediction is one of the basic tasks for medical diagnosis software. As of late, deep learning strategies have been effectively used in different applications to aid medical diagnosis. The contribution of deep learning traits and learning its concepts is helpful for the medical community. We will address research challenges and suggested solutions, as well as future promises and directions for further developments. Proposing new neural network algorithms, different machine learning techniques, and deep learning architectures could improve the detection of brain anomalies, providing timely diagnosis that could reduce the patient's risk for long-term symptoms and lasting deficits. This Special Issue will show the importance of these techniques in medical diagnostics and present future research topics that could be utilized to lead further research.

This paper presents a mobile, easy-to-maintain wireless electroencephalograph (EEG) system designed for work with children in a school environment. This EEG data acquisition platform is a small-sized, battery-powered system with a high sampling rate that is scalable to different channel numbers. The system was validated in a study of live z-score neurofeedback training for quantitative EEG (zNF-qEEG) for typical-reading children and those with developmental dyslexia (DD). This system reads and controls real-time neurofeedback (zNF) signals, synchronizing visual stimuli (low spatial frequency (LSF) illusions) with the alpha/theta (z-α/θ) score neural oscillations. The NF sessions were applied during discrimination of LSF illusions with different contrasts. Visual feedback was provided with color cues to remodulate neural activity in children with DD and their cognitive abilities. The combined zNF-qEEG and training with different visual magnocellular and parvocellular tasks (VTs) compensated for the deficits in the temporal areas affecting the occipitotemporal pathway more in the left-hemispheric ventral brain areas of the post-training children with dyslexia in the low-contrast LSF illusion and dorsal dysfunction in the high-contrast LSF illusion. The better α/θ scores for postD in the temporoparietal and middle occipital regions can be associated with an improvement in special frequency processing, while the better scores in the precentral and parietal cortices were due to an advancement in the temporal processing of the illusion. The improvements in the reading speeds were twice as high after 4 months of qEEG z-NF-VT training, with three times fewer omitted words and errors. Full article
