How We Filter Out Background Sounds When Speaking

Summary: Researchers have traced how the brain filters out background noise during speech using signals between the motor and auditory cortices. These milliseconds-long electrical signals, called auditory corollary discharge, originate…

Unexpected Sounds Boost Dopamine, Leading to Riskier Decisions

Summary: A new study shows that unexpected sounds can cause dopamine bursts in the brain, which may lead to riskier decision-making. Researchers found that participants were 4% more likely to…

Manipulating Brain Waves During Sleep With Sound

Summary: 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…

Pitch Perfect: Singing Earworms Reveals Surprising Trait

Summary: 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…

Classical Music Synchronizes Brain Waves, Improving Depression

Summary: 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…

Childhood Vision Loss Affects Sound Distance Judgement

Summary: 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…

Supranormal Hearing Achieved by Boosting Ear Synapses

Summary: Researchers have enhanced auditory processing in young mice by increasing inner ear synapses using neurotrophin-3. This study supports the hypothesis that synapse density impacts hidden hearing loss in humans.…

Imperfect Harmony: Rethinking Pythagoras’ Musical Consonance

Summary: New research challenges Pythagoras’s ancient theory on musical consonance, revealing our preference for slight imperfections in chords rather than the perfect integer ratios traditionally associated with beautiful music. The…

Loud Play, Silent Risk: Video Gaming’s Link to Hearing Loss

Summary: A systematic review indicates a potential risk of irreversible hearing loss and tinnitus among video gamers due to high sound levels. The study, encompassing over 50,000 individuals, found that…

Binaural Beats Boost Language Skills

Summary: Researchers conducted a new study exploring the effects of binaural beats (BB) on language comprehension. This study used electroencephalography (EEG) to examine how BB stimulation at beta and gamma…
