APRIL 29, 2025 — Researchers at the UTSA Sleep and Memory Computational Lab are studying how Rapid Eye Movement (REM) sleep could influence individuals who are regularly exposed to stressful experiences and are at higher risk of developing Post Traumatic Stress Disorder (PTSD).
The study, led by UTSA psychology professor Itamar Lerner, involves collaboration with first responders, such as firefighters and law enforcement personnel. The researchers examined their baseline levels of REM sleep, also known as “dream sleep,” and how that could have lasting effects on them over time.
“Our ongoing hypothesis is that REM sleep affects your ability to process threatening situations in two different ways, based on the predictiveness of the cues associated to the threat,” Lerner said. “Proving that would not only have clinical implications but also tell us something fundamental about the memory processes that occur in the brain and how sleep affects them.”
This research began as a pilot study two years ago. Since then, Lerner has secured a five-year, $725,000 CAREER award from the National Science Foundation for his research. This funding will allow his team to recruit more than 100 participants overall, with nearly 70 participants already enrolled.
In this video, hear from Professor Lerner, who is affiliated with MATRIX: The UTSA AI Consortium for Human Well-being, about this groundbreaking study and how it could have an impact on the future evaluation process of potential servicemen, law enforcement officers and first responders.

Covidence is a systematic & scoping review tool used to streamline the process of screening and reviewing articles. Using this software, research teams can easily import studies, perform automatic deduplication, and extract data using templates. This workshop will show attendees how to start a review in Covidence, add collaborators, and get started on screening.
Virtual (Zoom)In this workshop, attendees will be introduced to Pandas, a Python tool for working with data easily. It makes it simple to organize and analyze information when data is organized and categorized, like spreadsheets or tables.
Group Spot B, John Peace LibraryEach fall and spring semester, students convene at the Main Campus at UTSA with booths, ideas and prototypes. A crowd of judges, local organizations, students, faculty and sponsors walk around and talk to the students about their projects and ask questions. Students get the real-life experience of "pitching" their project with hopes of getting funding or support to move to the next level.
