Abstract
The organizational substate of brain activity depends upon numerous anatomical connection and pathway. Evoked brain potential called “P300” was discovered while monitoring brain activities of a patient counting the number of sound stimulation.
However, there are some problems; it is difficult to EEG the region beyond bones. Then, we propose a new method for EEG and local regions of the brain.
To determine the temperature distribution more accurately it would be required to introduce the more complicated model of heat removal effect by blood flow and the experimental results. These problem are left for the future investigation.
There exists a clear cut difference between indicative and nonindicative stimuli in respect to the shapes of brain waves, with the plus peak induced by indicative auditorial and tactile stimuli resulting around, 300 to 400ms after the time of presentation, exclusive of the time when tactile stimuli in a complicated pattern was presented. It was discovered in measuring temperature distribution on scalps that the distribution from each kind of stimuli correspond almost exactly to the regions of judgement and recognition activity, which have been identified on brain maps in the past.
