Daydreaming, where the mind wanders into spontaneous thoughts and scenarios, is a unique human ability that fosters creativity and reflection. A new study by University of Arizona researchers, published in Frontiers of Human Neuroscience, used transcranial-focused ultrasound (TFUS) to noninvasively alter the brain’s default mode network, which is active during daydreaming and memory recall. This technique enhanced mindfulness, representing a significant advancement in neuroscience. The study, led by Brian Lord, showed for the first time that the default mode network, particularly the posterior cingulate cortex, can be directly and noninvasively modulated.
