EEG-based time and spatial interpretation of activation areas for relaxation and words writing between poor and capable dyslexic children

2015 37th Annual International Conference of the IEEE Engineering in Medicine and Biology Society (EMBC), 2015

Symptoms of dyslexia such as difficulties with accurate and/or fluent word recognition, and/or poor spelling as well as decoding abilities, are easily misinterpreted as laziness and defiance amongst school children. Indeed, 37.9% of 699 school dropouts and failures are diagnosed as dyslexic. Currently, Screening for dyslexia relies heavily on therapists, whom are few and subjective, yet objective methods are still ...


Visual language task in EEG source localization analysis and functional MRI

2016 9th International Congress on Image and Signal Processing, BioMedical Engineering and Informatics (CISP-BMEI), 2016

Functional areas of language process are mainly linked with Wernicke area responsible for understanding language and Broca area connected with speech production. In this study Wernicke area is detected using ERP source localization and compared with fMRI study. The same neural networks are revealed in the both methods. Standardized low resolution electromagnetic tomography (sLORETA) seems to be sufficient for source ...


Dynamic diaschisis: anatomically remote and context-sensitive human brain lesions

5th IEEE EMBS International Summer School on Biomedical Imaging, 2002., 2002

Functional neuroimaging was used to investigate how lesions to the Broca's area impair neuronal responses in remote undamaged cortical regions. Four patients with speech output problems, but relatively preserved comprehension, were scanned while viewing words relative to consonant letter strings. In normal subjects, this results in left lateralized activation in the posterior inferior frontal, middle temporal, and posterior inferior temporal ...

  • Dipole localization of eeg and its application to detection of origin of epilepsy

    The paper introduces a confidential region proposed by T. Yamazaki et al., which is equipped with the equivalent dipole source localization software; SinaPointPro (NEC Corporation). This confidence limit is defined on a direction of the radius. This method enables to detect the origin of the epilepsy. And also the paper treats a series of its applications by the present author. The author and his collaborators have recorded electroencephalograms (EEGs) from subjects viewing four types of Kanji and arrows representing directional meaning. Subjects were asked to read them silently. The equivalent current dipole source localization (ECDL) method has been applied to these event related potentials: averaged EEGs. ECDs were localized to the right and left frontal lobes at latency after 500ms in both cases. Polarities of ERPs were also opposite in the case of opposite directions, and the moments of localized ECDs at these latencies were opposite. Pathways of ECDs in silent reading are almost the same in cases of Kanji and arrow. In these cases, no ECD was localized to the Wernike's area and the angler gyrus those are related to the auditory language area, however, ECDs were localized to the Broca's area that is said to be the language area for speech.

  • EEG-based time and spatial interpretation of activation areas for relaxation and words writing between poor and capable dyslexic children

    Symptoms of dyslexia such as difficulties with accurate and/or fluent word recognition, and/or poor spelling as well as decoding abilities, are easily misinterpreted as laziness and defiance amongst school children. Indeed, 37.9% of 699 school dropouts and failures are diagnosed as dyslexic. Currently, Screening for dyslexia relies heavily on therapists, whom are few and subjective, yet objective methods are still unavailable. EEG has long been a popular method to study the cognitive processes in human such as language processing and motor activity. However, its interpretation is limited to time and frequency domain, without visual information, which is still useful. Here, our research intends to illustrate an EEG-based time and spatial interpretation of activated brain areas for the poor and capable dyslexic during the state of relaxation and words writing, being the first attempt ever reported. From the 2D distribution of EEG spectral at the activation areas and its progress with time, it is observed that capable dyslexics are able to relax compared to poor dyslexics. During the state of words writing, neural activities are found higher on the right hemisphere than the left hemisphere of the capable dyslexics, which suggests a neurobiological compensation pathway in the right hemisphere, during reading and writing, which is not observed in the poor dyslexics.

  • Dynamic diaschisis: anatomically remote and context-sensitive human brain lesions

    Functional neuroimaging was used to investigate how lesions to the Broca's area impair neuronal responses in remote undamaged cortical regions. Four patients with speech output problems, but relatively preserved comprehension, were scanned while viewing words relative to consonant letter strings. In normal subjects, this results in left lateralized activation in the posterior inferior frontal, middle temporal, and posterior inferior temporal cortices. Each patient activated normally in the middle temporal region but abnormally in the damaged posterior inferior frontal cortex and the undamaged posterior inferior temporal cortex. In the damaged frontal region, activity was insensitive to the presence of words but in the undamaged posterior inferior temporal region, activity decreased in the presence of words rather than increasing as it did in the normal individuals. The reversal of responses in the left posterior inferior temporal region illustrate the context-sensitive nature of the abnormality and that failure to activate the left posterior temporal region could not simply be accounted for by insufficient demands on the underlying function. We propose that, in normal individuals, visual word presentation changes the effective connectivity among reading areas and, in patients, posterior temporal responses are abnormal when they depend upon inputs from the damaged inferior frontal cortex. Our results serve to introduce the concept of dynamic diaschisis; the anatomically remote and context-sensitive effects of focal brain lesions. Dynamic diaschisis reveals abnormalities of functional integration that may have profound implications for neuropsychological inference, functional anatomy and, vicariously, cognitive rehabilitation.

  • Spatiotemporal human brain activities on recalling body parts

    The authors measured electroencephalograms (EEGs) from subjects looking at line drawings of body parts and recalling their names silently. The equivalent current dipole source localization (ECDL) method is applied to the event related potentials (ERPs): summed EEGs. ECDs are localized to the primary visual area VI, to the ventral pathway (ITG: Inferior Temporal Gyrus), to the parahippocampus (ParaHip), the right angular gyrus (AnG), to the right supramarginal gyrus (SMG) and to the Wernike's area. Then ECDs are localized to the Broca's area, to the postcentral gyrus (PstCG) and to the fusiform gyrus (FuG), and again to the Broca's area. These areas are related to the integrated process of visual recognition of pictures and the retrieval of words. Some of these areas are also related to image recognition and word generation. And process of search and preservation in the memory is done from the result of some ECDs to the paraHip.

  • Chinese character and figure cognitive processing in the left Broca's area on inflated cortex

    The cerebral cortex is the main target of analysis in many functional magnetic resonance imaging (fMRI) studies; statistical analysis can be restricted to the subset of the voxels obtained after cortex segmentation. We used a event- related design and contrasted the cognitive processing of Chinese character and figure in left Brodmann areas 44 and 45, which constitute Broca's region. in Chinese-speaking individual. Participants carried out a visual judgments task on a list of randomly intermixed Chinese characters and figure. The fMRI data were mapped directly onto cortical surface models. Processing of Chinese characters and figure judgments activated a comparable network of brain regions. In Broca's area, the Chinese character judgment task is also similar but more activations than figure judgment task. The result confirms a popular view that this area plays a role in grapheme-to-phoneme conversion.

  • Electroencephalographic identifiers of reading abilities in turkish language

    Fluent reading requires learning the print knowledge of alphabet symbols (letters), rapid automatic naming and phonological awareness skills. In this study, electroencephalo-graphic brain signals of 17 subjects were measured with an eMotiv EPOC+ headset before, during and after a computer-based training session. For the training, distorted letter prints were created by rotating Turkish letters 180 degrees along the y-axis. Using these distorted letters two different texts, each 150 words in length, were created. Subjects were asked to read these texts before and after the training session. We investigated whether there is an improvement in reading speed and a decrease in number of errors due to the computer-based training and whether we can correlate the success of training with any characteristic of any EEG brain signals. Based on our analysis of the EEG data collected throughout the experiment, we observed that the frequency modulation across resting states in the Theta at the Broca Area (F7 and FC5) predicts individual reading performance measures. Even though there exist a variety of studies indicating a relation of Theta band power and learning performance, EEG measurements with eMotiv EPOC+ had not been previously reported with a Turkish alphabet learning task.
