The integration of sensory signals from different modalities requires flexible interaction of remote brain areas. One candidate mechanism to establish local and long-range communication in the brain is transient synchronization of neural assemblies. In addition to the analysis of oscillatory power, assessment of the phase dynamics of multiple brain signals(More)
In this study, we used a novel multisensory attention paradigm to investigate attention-modulated cortical oscillations over a wide range of frequencies using magnetencephalography in healthy human participants. By employing a task that required the evaluation of the congruence of audio-visual stimuli, we promoted the formation of widespread cortical(More)
Multiferroic BaMnF4 powder was prepared by hydrothermal method. Hysteretic field dependent magnetization curve at 5 K confirms the weak ferromagnetism aroused from the canted antiferromagnetic spins by magnetoelectric coupling. The blocking temperature of 65 K for exchange bias coincides well with the peak at 65 K in the zero-field cooled(More)
The clear understanding of exchange interactions between magnetic ions in substituted BiFeO 3 is the prerequisite for the comprehensive studies on magnetic properties. BiFe 0.5 Mn 0.5 O 3 films and BiFeO 3 / BiMnO 3 superlattices have been fabricated by pulsed laser deposition on (001) SrTiO 3 substrates. Using piezoresponse force microscopy (PFM), the(More)
