A UCLA Health study shows that repetitive practice enhances brain memory pathways, stabilizing working memory and improving skill accuracy, with implications for treating memory disorders.has revealed that repetitive practice not only enhances skill acquisition but also significantly alters the brain’s pathways for memory.and co-led by Rockefeller University, sought to unravel how the brain’s ability to retain and process information, known as working memory, improves through training.
To test this, researchers tasked mice with identifying and recalling a sequence of odors over the course of two weeks. Researchers then tracked neural activity in the animals as they practiced the task by using a novel, custom-built microscope that can image cellular activity in up to 73,000 neurons simultaneously throughout the cortex.The study revealed a transformation in the working memory circuits located in the secondary motor cortex as the mice repeated the task through time.
These changes give insights into why performance becomes more accurate and automatic following repetitive practice. “This insight not only advances our understanding of learning and memory but also has implications for addressing memory-related disorders,” Golshani said.
