        abstract = {The research of Brain ECVT application to observe the pattern of brain signals
from the prefrontal cortex area in elderly subjects has been successfully done.
This study includes several stages such as characterization of instruments,
measuring capacitance in a static medium and observation of prefrontal cortex
area of the brain using Brain ECVT. The results showed that the level of accuracy
of the instrument based on the measurement of air and water medium is 99.12\%.
The precision of measurement in the air and water medium, are 99.61\% and
99.23\%, respectively. Measurements on the static medium indicate that the sensor
of 32 electrodes Brain ECVT was capable of measuring differences in capacitance
to the medium, such as alcohol, glycerin and TiO2. Further observation in the
prefrontal cortex area of the brain using Brain ECVT in elderly subjects as the test
subject and the adult subjects as the control subjects. From the result of the
recording was obtained signal and image data of the brain. The signal data was
analyzed using statistical Kolmogorov-Smirnov test (k-s test) to see if there was a
significant difference between the signals of the brain in elderly subjects and the
adult subjects. While the image data was analyzed using three methods, namely
Spatial Image Error (SIE), Distribution error (DE), and Correlation Coefficient
(CC). Results of the analysis showed significant differences between elderly
subjects and adult subjects both based on the measurable signal and the image of
the brain. The differences in capacitance measured by ECVT illustrates the
differences in the brain permittivity distribution. This difference occurs in the
elderly due to undergo a process of degeneration of nerve cells (neurons) due to
aging factors.}
