Outline of Final Research Achievements

In this study we used magnetoencephalography (MEG) to investigate changes in inter-regional connectivity underlying attentional control. We analyzed the MEG signal in the cue-target interval in different attention tasks to examine neuronal oscillation and inter-regional connectivity during attentional control. Time-frequency analysis showed that in the cue-target interval, beta activity was desynchronized in the hemisphere contralateral to the attended side. Sensory-evoked responses were increased by spatial attention, irrespective of sensory modalities attended. Also, inter-regional connectivity between prefrontal and parietal regions was increased during attentional control compared with the baseline period. These findings support the hypothesis that early sensory processing in modality-specific cortices is regulated, irrespective of the sensory modality, by attentional control signals from the lateral prefrontal cortex in the human brain.
