With respect to the dramatic increasing use of electronically communicators and wireless modems, concerns have been raised about the possible effects of emitted electromagnetic radiation on human brain. In this paper, the effects of high-frequency wireless modem waves on the brain signal are investigated. To this end, the Electroencephalograph (EEG) recording of 15 volunteers is examined in fou...
Recently, methodologies for developing brain-computer interface (BCI) games using the BCI have been actively researched. The existing general framework for processing brain waves does not provide the functions required to develop BCI games. Thus, developing BCI games is difficult and requires a large amount of time. Effective BCI game development requires a BCI game framework. Therefore the BCI...
Previous studies found that performance on the remote associates test (RAT) improves after a period of incubation and that increased alpha brain waves over the right posterior brain predict the emergence of RAT insight solutions. We report an experiment that tested whether increased alpha brain waves during incubation improve RAT performance. Participants received two blocks of RAT items (RAT1 ...
We experience the world around us as “continuous,” which means everything around us seems uninterrupted and ongoing. But how does our brain achieve that? Here, we suggest that the brain samples our environment in separate snapshots. We demonstrate that brain waves work just like a flipbook, where the rapid stream of related pictures creates the illusion of a continuous movie. We present results...
The human brain produces a characteristic electrical response to relevant events that occur unexpectedly. Recent reports have suggested that a prominent part of this event-related brain potential--the P3 wave--may be related to memory functions and may arise from activity within the medial temporal lobe, especially the hippocampus. The latter idea was tested by means of epidural recordings of b...
We investigate a feature extraction method that is effective for biometric identification using brain waves in this paper. We extract power spectrums of theta waves, alpha waves, beta waves and gamma waves for the quantity of personal characteristic. We measure brain waves with five tasks and multi-channel electroencephalograph to analyze each error rate. As a result, the error rate of the alph...
Slow wave sleep (SWS) is associated with spontaneous brain oscillations that are thought to participate in sleep homeostasis and to support the processing of information related to the experiences of the previous awake period. At the cellular level, during SWS, a slow oscillation (<1 Hz) synchronizes firing patterns in large neuronal populations and is reflected on electroencephalography (EEG) ...
