Cerebral activity measuring apparatus

摘要: PROBLEM TO BE SOLVED: To provide a cerebral activity measuring apparatus capable of showing in what region the head functional deterioration progresses. SOLUTION: A plurality electroencephorogram sensors are attached to an examinee measure scalp potentials and alpha wave components measured converted numerical value data calculate dipole degrees at every sampling point time while average values within definite range square errors due equivalent dipoles peak occurring points or variances from calculated with respect respective electroencepharogram contour map related distribution on corresponding brain surface. Alternatively, squares recorded by averaged over several sec these large number reference persons standard deviation person group individual examinees ranked basis present thereof allotted surfaces draw maps. The local neuron function shown COPYRIGHT: (C)2005,JPO&NCIPI
