Wayne State University researchers are using photoacoustic imaging to observe brain activity and, in the process, discovering more about how it responds to different types of learning and experiences.

The team’s findings were recently published in the journal Photoacoustics.

The study, “Use of pattern recognition in photoacoustic imaging to identify neuronal ensembles in the prefrontal cortex of rats undergoing conditioned fear learning,” stemmed from a project by Wayne State University School of Medicine alumnus, James Matchynski, M.D., Ph.D., and was led by School of Medicine faculty members Shane Perrine, Ph.D., associate professor of psychiatry and behavioral neurosciences, and Alana Conti, Ph.D., professor of psychiatry and behavioral neurosciences and director of the Translational Neuroscience Program. The team collaborated with colleagues in the Department of Biomedical Engineering at the University of Illinois Chicago.
