NIRS and CNAP—Pairing great tools for great data

NIBP sensor

Cerebral hemoglobin concentration (blood mass in the brain) is frequently measured in the prefrontal cortex, and systemic arterial blood pressure is known to be a variable factor based on the hemoglobin concentration. A leg pressure cuff was used to constrict and release blood flow to create a measurable event. Using a NIBP100D and a NIRS system, variability in time between when this event measured in the fingers and the brain were measured. Moving forward, these researchers hope to shine light on how noninvasive blood flow recorders can take place of traditional blood pressure measurement methods.

Predicting Risk when driving with Physiology

While we wait for the advent of autonomous vehicles, one of the most dangerous events while driving involves merging onto freeways or changing lanes. These researchers investigated methods for predicting the risks involved based on vehicle dynamic data and the driver’s physiological functions. Because this study made use of the 16-channel MP160 Data Acquisition System, subjects were able to have a variety of physiological signals measured simultaneously, including eye movement and heart rate variability.

New cerebrovascular agent with hypotensive activity

noninvasive blood pressure ampVascular injuries of the brain and hypertension can cause a certain disorder known as the Hypertensive cerebrovascular crisis. In a trial of a new chemical nerve agent aimed at blocking the neurological channels causing the crisis, researchers utilized the NIBP200 small animal tail noninvasive blood pressure system to measure Systolic BP through rat tails and measure hypertension, effectively measuring the ability of this pharmacological agent to function as intended.

Smelling your Emotional State Our sense of smell delivers important information to our brains, such as whether or not food is bad, or reminding us of a pleasant memory (crisp, fall air, anyone?). This fMRI-based study recorded PPG using a Photoplethysmograph Transducer for MRI connected to a PPG100C-MRI Amplifier. A differential pressure transducer continuously recorded variations in […]
