Although frontal-posterior global theta synchronization appears in modality-specific WM, local theta synchronization in frontal regions has been found in modality-independent WM. How frontal theta oscillations separately synchronize with task-relevant sensory brain areas remains an open question. Here, we focused on theta-alpha phase relationships in frontal areas using EEG, and then verified their functional roles with mathematical models. EEG data showed that the relationship between theta (6\u2009Hz) and alpha (12\u2009Hz) phases in the frontal areas was about 1:2 during both auditory and visual WM, and that the phase distributions between auditory and visual WM were different. Next, we used the differences in phase distributions to construct FitzHugh-Nagumo type mathematical models. The results replicated the modality-specific branching by orthogonally of the trigonometric functions for theta and alpha oscillations. Furthermore, mathematical and experimental results were consistent with regards to the phase relationships and amplitudes observed in frontal and sensory areas. These results indicate the important role that different phase distributions of theta and alpha oscillations have in modality-specific dissociation in the brain.", "subitem_description_type": "Abstract"}]}, "item_5_publisher_27": {"attribute_name": "\u51fa\u7248\u8005", "attribute_value_mlt": [{"subitem_publisher": "Nature Publishing Group"}]}, "item_5_relation_10": {"attribute_name": "PubMed\u756a\u53f7", "attribute_value_mlt": [{"subitem_relation_type_id": {"subitem_relation_type_id_text": "28266595", "subitem_relation_type_select": "PMID"}}]}, "item_5_relation_11": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type_id": {"subitem_relation_type_id_text": "10.1038/srep42776", "subitem_relation_type_select": "DOI"}}]}, "item_5_rights_12": {"attribute_name": "\u6a29\u5229", "attribute_value_mlt": [{"subitem_rights": "\u00a9 The Author(s) 2017"}, {"subitem_rights": "This work is licensed under a Creative Commons Attribution 4.0 International License.
