%X 4D Brain ECVT is the latest non-invasive brain imaging instrument. In this research, the human brain activity in the prefrontal area during stress and relax conditions was recorded using this instrument, along with measurements of blood pressure, heart rate, and breathing frequency. The data shows that under stress condition, the voltage value of this instrument is irregular compared to the relaxed state. The same is also indicated by the data of blood pressure, heart rate, and breathing frequency. Through this study, it was concluded that 2-Electrode 4D Brain ECVT can be an alternative instrumentation to record the activity of the human brain. %L repository996 %N 10 %A Siska Ayu Nirmala %A Rizki Edmi Edison %A Rizki Nurfauzi %A Luh Putu Suta Haryanthi %A Muhammad Fathul Ihsan %A Rizki Maharani %A Warsito Purwo Taruno %I American Scientific Publisher %J Advanced Science, Engineering, and Medicine %P 869-871 %T Voltage Value of 2-Electrode 4D Brain ECVT of Human Brain During Stress and Relaxed Conditions %D 2015 %V 7
