It says 'caution do not use with human subjects' on the front
Abstract?The electrical conductivity of human cerebrospinal uid
(CSF) from seven patients was measured at both room temperature
(25 C) and body temperature (37 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.
