在室温（25℃）和体温（37℃）下测量了7例患者的脑脊液（CSF）的电导率。在10hz - 10khz的频率范围内，室温电导率为1.45 S/m，而体温电导率为1.79 S/m，高出约23%。近二十年来，人脑中电源的建模者低估了人类脑脊液电导率高达44%，这应该得到纠正，以提高源定位模型的准确性。
The electrical conductivity of human cerebrospinal fluid (CSF) from seven patients was measured at both room temperature (25 degrees C) and body temperature (37 degrees C). Across the frequency range of 10Hz-10 kHz, room temperature conductivity was 1.45 S/m, but body temperature conductivity was 1.79 S/m, approximately 23% higher. Modelers of electrical sources in the human brain have underestimated human CSF conductivity by as much as 44% for nearly two decades, and this should be corrected to increase the accuracy of source localization models.
