Sound stimulation can manipulate brain waves during REM sleep, a stage crucial for memory and cognition. Using advanced technology, researchers were able to increase the frequency of brain oscillations that slow down in dementia patients, potentially improving memory functions. The non-invasive technique could pave the way for innovative treatments for dementia by targeting brain activity during sleep. This approach offers hope for enhancing memory and cognition with minimal disruption to patients' lives.

Researchers discovered that nearly 45% of people sing earworms in perfect pitch, suggesting a hidden "perfect pitch" ability in the general population. Even without formal musical training, participants accurately recalled the pitch of familiar songs, challenging common perceptions about musical abilities. This finding highlights the brain's remarkable capacity to store precise musical memories and suggests that many people may have untapped musical potential.

Western classical music can significantly affect brain activity, particularly in people with treatment-resistant depression. By measuring brainwaves and neural imaging, scientists discovered that music synchronizes neural oscillations between brain regions associated with sensory and emotional processing, enhancing mood. This study suggests that personalized music therapy could be a powerful tool for treating depression, especially when integrated with other sensory stimuli.

Researchers discovered that humans can detect water temperature through its sound. Using machine learning, they analyzed how people perceive thermal properties via auditory cues.

New research reveals that individuals who experience vision loss before age 10 struggle more with judging sound distance compared to those who lose sight later in life. This difficulty in perceiving the location of sounds has significant implications for safety and navigation. The study highlights the need for tailored healthcare solutions for those with early vision loss to enhance their quality of life.
