A new study led by UCLA Health has shown that repetitive practice not only is helpful in improving skills but also leads to profound changes in the brain’s memory pathways.
The research, published in the journal Nature 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 to image cellular activity in up to 73,000 neurons simultaneously throughout the cortex.
The study revealed a transformation...
