Abstract:
There has been recent interest in the concept of connecting a computer to the brain to control brain functions. However, there are challenges that must be overcome in developing such a computer-brain interface, including a selection of nucleus that is stimulated, and an implantable electrode and electrical stimulator. Another important issue is the designing of the controller, that is, determining how to encode as an electrical signal the information to be sent to the brain. We have applied system identification theory, a method for evaluating dynamic characteristics of a system, to the arterial blood pressure control system of the brain. Our results show that (1) the stimulation-arterial blood pressure response relationship can be described as a mathematical model, which gives a good prediction of the arterial blood pressure response, facilitating the designing of a computer-brain interface, and (2) the arterial blood pressure can be actually controlled using a computer-brain interface.

Equipments Used To Measure Blood Pressure
This invasive approach involves cannulating a peripheral artery. During each cardiac contraction, pressure generates mechanical motion within the catheter, transmitted through rigid, fluid-filled tubing to a transducer. This transducer converts mechanical motion into electrical signals displayed as waveforms on a monitor. An automatic flushing system prevents blood backflow. Due to the potential risk of unexpected arterial blood loss, this method is primarily used in intensive...

Monitoring Both Arms:
Monitoring BP in both arms during the initial assessment is advisable, as the systolic value may differ by five to ten mm Hg between arms. For subsequent BP assessments, use the arm with the higher reading.
