Supranormal Hearing Achieved by Boosting Ear Synapses

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. The findings could lead to new treatments for hearing disorders by preserving or regenerating synapses. The study reveals that boosting synapses not only improves hearing but also enhances auditory information processing.

How The Brain Predicts Music

A new study reveals how our brains recognize and predict musical sequences, activating areas related to sound, memory, and emotions. This understanding could help develop tools to detect cognitive decline and dementia. The study measured brainwaves of 83 participants, showing the complex neural processes involved in music perception. Future research will explore how these mechanisms change with age and cognitive impairments.

Unveiling the Brain’s Response to Sound

Researchers discovered how the brain translates sounds into actions, a key to understanding sensory decision-making. Their study reveals that both sensory and future action-related signals are present in the cortex, challenging previous beliefs that these areas are functionally distinct.

How Our Brains Process Music

Researchers unlocked how the brain processes melodies, creating a detailed map of auditory cortex activity. Their study reveals that the brain engages in dual tasks when hearing music: tracking pitch with neurons used for speech and predicting future notes with music-specific neurons.

When Elders Can’t Hear Words at a Noisy Holiday Gathering, Too Many Brain Cells May Be Firing at Once

Older mice were less capable than younger mice at "turning off" certain actively firing neurons when exposed to ambient noise. The result causes a fuzzy soundscape that makes it difficult for the brain to focus on one type of sound and filter out other surrounding sounds.

Our Brains ‘Time-Stamp’ Sounds to Process the Words We Hear

The brain processes speech by using a buffer, maintaining a "time stamp" of the past three speech sounds. Findings also reveal the brain processes multiple sounds at the same time without mixing up the identity of each sound by passing information between neurons in the auditory cortex.

Why Are Sounds Not Perceived Under Anesthesia?

Under anesthesia, neuron assemblies that respond to sound become indistinguishable from spontaneously active neurons. Findings suggest the state of unconsciousness produced by anesthesia forces the cerebral cortex to mask sensory input with spontaneous neural activity.

Somatostatin Neurons Cooperate in the Cerebral Cortex

In the cerebral cortex, when somatostatin neurons become active, other nearby somatostatin neurons became active as well. The distance over which somatostatin neurons shared activity expanded in the posterior parietal cortex.

Misophonia Is More Than Just Hating the Sound of Chewing

A new study contradicts previous findings that suggest misophonia is caused by a supersensitive connection between the auditory cortex and orofacial motor control areas of the brain.
