New Citations | Marking Events with BIOPAC

BIOPAC offers complete systems for life science research and education—human, animal, or in vivo studies, as well as powerful software and automated analysis including industry-standard data acquisition amplifiers, transducers & electrodes. BIOPAC can be used inside or outside the lab to measure physiology anytime, anyplace.

Impact of Movie Editing on Perceptual Conflict Mechanisms

Our ability to watch and understand films effortlessly is a remarkable and understated feat of human cognition. Using different styles of editing in movies as event markers, these scientists recorded EDA using BIOPAC, and extracted the event-related skin-conductance responses (SCRs) around different events to compare the relationship between cognitive conflict and emotional response.

Tongue Pressure, Swallowing, and Respiration—Oh My!

Swallowing is as important to living as breathing. Without it, we couldn’t eat food or drink water. A key to swallowing is tongue pressure to move food from the mouth to the stomach. In this experiment, researchers were trying to measure tongue pressure through noninvasive means. With a clever event marking system and a BIOPAC pressure transducer with a data acquisition system, the study was able to acquire meaningful physiological data.

Using Ketamine for Acute Pain

Is there an alternative to nonsteroidal anti-inflammatory drugs (NSAIDs) for acute pain in a surgical setting? This study aimed to see if ketamine could be a valid alternative for pain relief during surgery. Using AcqKnowledge 5.0, researchers measured EEG data from lab mice marking changes in temperature and dosing.
