Two regions of the brain critical to integrating semantic information while reading, UTHealth Houston research finds
Newswise — Two different regions of the brain are critical to integrating semantic information while reading, which could shed more light on why people with aphasia have difficulty with semantics, according to new research from UTHealth Houston.
The study, led by first author Elliot Murphy, PhD, postdoctoral research fellow in the Vivian L. Smith Department of Neurosurgery with McGovern Medical School at UTHealth Houston, and senior author Nitin Tandon, MD, professor and chair ad interim of the department in the medical school, was published today in Nature Communications.
Language depends largely on the integration of vocabulary across multiple words to derive semantic concepts, including reference to events and objects, and statements of truth. However, the way people integrate semantic information while reading remains undetermined.
“Typically, we take pieces from different words and derive a meaning that’s separate. For example, one of the definitions in our study was ‘a round red fruit’ — the word ‘apple’ doesn’t appear in that sentence, but we wanted to know how patients made that inference,” Murphy said. “We were able to expose the dynamics of how the human brain integrates semantic information, and which areas come online at different stages.”
To uncover this, researchers studied intracranial recordings in 58 epilepsy patients who read written word definitions, which were either referential or nonreferential to a common object, as well as phrases that were either coherent (“a person at the circus who makes you laugh”) or incoherent (“a place where oceans shop”). Sentences were presented on the screen one word at a time, and researchers focused their analysis over the time window when the final word in the sentence was presented.
Overall, they found that different areas of the language network showed sensitivity to meaning across a small window of rapidly cascading activity. Specifically, they discovered the existence of complementary cortical mosaics for semantic integration in two areas: the posterior temporal cortex and the inferior frontal cortex. The posterior temporal cortex is activated early on in the semantic integration process, while the inferior frontal cortex is particularly sensitive to all aspects of meaning, especially in deep sulcal sites, or grooves in the folds of the brain.
Murphy said these findings can help illuminate the inner dynamics of aphasia, a disorder that affects a person’s ability to express and understand written and spoken language. It can occur suddenly after a stroke or head injury, or develop slowly from a growing brain tumor or disease.
People with aphasia often have difficulty with semantic integration, meaning that while they can understand individual words, they cannot make additional semantic inferences.
“Both the frontal and posterior temporal cortexes disrupt semantic integration, which we see happen in individuals with various aphasias,” Murphy said. “We speculate that this intricately designed mosaic structure makes some sense out of the varying semantic deficits people experience after frontal strokes.”
Co-authors with UTHealth Houston included Kathryn M. Snyder, MD/PhD student; and Patrick S. Rollo, research associate and third-year medical student, both with the Vivian L. Smith Department of Neurosurgery and the Texas Institute for Restorative Neurotechnologies (TIRN) at McGovern Medical School. Tandon is the Nancy, Clive and Pierce Runnels Distinguished Chair in Neuroscience of the Vivian L. Smith Center for Neurologic Research and the BCMS Distinguished Professor in Neurological Disorders and Neurosurgery with McGovern Medical School and a member of TIRN. Tandon is also a faculty member with The University of Texas MD Anderson UTHealth Houston Graduate School of Biomedical Sciences, where Snyder is also a student. Kiefer J. Forseth, MD, PhD, and Cristian Donos, PhD, both formerly with UTHealth Houston and now with the University of California at San Diego and the University of Bucharest in Romania, respectively, also contributed to the study.

6 Tips to Improve Sleep Quality for Overall Well-Being
(Family Features) Despite a rising number of people searching for the term “sleep” in 2023, nearly 1 in 3 U.S. adults report not getting enough of it, per the Centers for Disease Control and Prevention.
The Quality of Sleep
As a foundation for overall well-being, getting quality sleep is key to achieving goals and being present in daily life. Without it, you’re more likely to lack the stamina and energy to follow through on your ambitions.
To help people realize the foundational role sleep plays in everyday successes, Natrol – a leading sleep, mood and stress supplement brand based on Nielsen data – alongside Dr. Jess Andrade are working together to help people improve their sleep quality and habits so they can conquer their wellness goals this year and beyond.
“From consistent exercise to eating healthy and even daily journaling, it may seem like all your priorities are in order, but without sleep, you won’t be able to reap the full benefits of your hard work,” Andrade said. “Often overlooked, getting quality sleep is a fundamental piece to improving overall wellness and it doesn’t have to be complicated. Creating small, achievable changes in our daily sleep routines can lead to long-lasting lifestyle habits for the better.”
Consider these tips from Andrade to help improve your sleep quality so you can achieve your goals.
1. Prioritize Movement and Light Exposure in the Morning
Whether you’re a yogi or prefer a simple stretch when your feet hit the floor, movement and light during the day can help stimulate quality sleep later that night.
2. Understand Sleep Gains are Just as if Not More Important Than Gym Gains
If you’re focusing on fitness goals, you’ll need adequate sleep to see successful results. If you’re a morning workout warrior, schedule earlier bedtimes to ensure you get the recommended 7-8 hours of sleep. For evening workouts, aim to end your sweat session as early in the evening as possible; too much physical activity before bed can keep you up at night.
3. Make Your Bedroom a Sanctuary
Make your bedroom a sleep sanctuary. Keep the room dark, noise-free, and comfortable with the thermostat set at 65-67 F for better sleep conditions.
4. Set Nightly Rituals to Unwind
Create nightly rituals that activate circadian rhythms and allow your body to unwind. Consider activities that relax you the most, like taking a bath, reading a book, journaling or sipping decaffeinated nighttime tea.
5. Try Incorporating a Drug-Free Sleep Aid
If you follow good bedtime habits but still occasionally struggle to fall or stay asleep, try a low-milligram melatonin supplement, like those from Natrol, that are designed to help you get a good night’s sleep so you wake up refreshed and ready to conquer your goals.†
6. Follow the 10-3-2-1-0 method
To help you fall asleep and wake up feeling revitalized, Andrade recommends the 10-3-2-1-0 method: Decrease caffeine intake at least 10 hours before bed. Avoid eating bothersome foods 3 hours prior to heading off to sleep. Engage in relaxing activities like reading at the 2-hour mark and cut out screentime with 1 hour to spare. Ultimately, these habits can lead to zero times hitting snooze the next morning.

Learn CPR as a Life-Saving Skill
(Family Features) While many Americans agree Conventional CPR (cardiopulmonary resuscitation) or Hands-Only CPR (HOCPR) significantly improve a person’s chance of survival from cardiac arrest, less than half are confident they can perform either Conventional CPR or HOCPR in an emergency.
Learning CPR
Black or Hispanic adults who experience cardiac arrest outside a hospital setting are substantially less likely to receive lifesaving care from a bystander. In spite of these survey results, the American Heart Association is working to change this by empowering members of these communities to learn lifesaving CPR, and a growing segment of respondents are willing to act in an emergency.
The American Heart Association’s 2023 survey also revealed that as a result of the organization’s efforts to change attitudes about performing CPR, which can lead to lifesaving results, more than half of African Americans said they would be willing to perform CPR in an emergency compared to 37% two years ago. Additionally, Hispanic and Latino respondents are more confident in their abilities to perform CPR.
Committed to turning a nation of bystanders into lifesavers, the American Heart Association’s multiyear initiative, Nation of Lifesavers, helps teens and adults learn how to perform CPR and use an automated external defibrillator (AED); share that knowledge with friends and family; and engage employers, policymakers, philanthropists and others to create support for a nation of lifesavers.
“Each of us has the power in our own hands to respond to a sudden cardiac arrest,” said Anezi Uzendu, M.D., American Heart Association expert volunteer. “We simply need to know what to do and have the confidence to act.”
The long-term goal: to ensure that in the face of a cardiac emergency, anyone, anywhere is prepared and empowered to perform CPR and become a vital link in the chain of survival, aiming to double the survival rate of cardiac arrest victims by 2030. It takes just 90 seconds to learn how to save a life using HOCPR, which can be equally as effective as traditional CPR in the first few minutes of cardiac arrest.
Nationally supported by the Elevance Health Foundation, the American Heart Association’s HOCPR campaign is focused on chest compression-only CPR. If a teen or adult suddenly collapses due to a cardiac event, you can take two steps to save a life: immediately call emergency services and use these tips to begin performing HOCPR.
- Position yourself directly over the victim.
- Put the heel of one hand in the center of the chest and put your other hand on top of the first.
- Push hard and fast in the center of the chest at a rate of 100-120 beats per minute, which is about the same tempo as the song “Stayin’ Alive” by the Bee Gees, and at a depth of approximately 2 inches.
- Continue compressions and use an AED, if available, until emergency help arrives.
