Penn State researchers have developed a set of tools and methods to better monitor and analyze signals related to sleep and fidget in rodent brain studies. Considering the pillars of biological research, rodent studies provide an early understanding of the development of brain functions and are the pillars on which human studies are built, according to Patrick Drew, Huck Distinguished Associate Professor of Neural Engineering and Neurosurgery and a professor of engineering. and mechanics.

The tool allows researchers to monitor behavioral changes such as rodent heart rate, student diameter and whisker movements while I noticed reading, and set of numbers to measure and evaluate data. They published a complete guide on how to do it with their tools, their number and lab setup pictures in it Neurophotonics, Magazine published by SPIE, or the international community for visual and photographic devices.

According to Drew, variables can cause internal oscillations computer work that in the past they could have been interpreted aloud but now it is known that changes are characteristic. Creating and studying these mental functions is important for better understanding of the brain, but getting one to observe experiments and study movements and states of sleep by hand is a serious and subjective issue. human error.

To address this, researchers’ approach to monitoring the nature of rowan violence at the same time as nerve impulses is aroused by the uncertainty presented by human interpretation.

“What people always do in both animal and human species is that, ‘I introduced a stimulant and that happened,’ ‘Drew said. – whether they were vigilant. or dozing off-and their fidgeting habits. These behaviors lead to brainstorming activities. If cassava stimulates alcoholism and myocardial infarction, it not only shows up in brain tissue; appears everywhere, including the visual cortex, e.g. As a psychologist, you should never forget that it has to do with the body, and the body and the brain go through each other in ways that we do not yet understand. The detailed instructions we have published will make it easier for people to study and understand all of this. ”

According to the researchers, the tools and methods they share should be particularly useful in sleep studies but may also apply to other areas of psychology. For example, Drew explained that researchers can detect changes in the blood vessels of the brain, which neurons process to maintain. brain health and scientists use signaling in imaging studies.

Qingguang Zhang, an assistant professor of engineering and mechanics in Penn State and the first author of the paper, said, “Our lab uses engineering techniques to solve life sciences, so we are combining different research areas.” “As members of the Center for Neural Engineering and the Huck Center for Life Sciences, we have provided this group of people and we can understand the problem from both perspectives. We have developed tools that will help psychologists to analyze data and and find out the next step. ”
