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.

Scientists Discover Mechanism of Hearing

For the first time, researchers have captured in near-atomic detail the structure of a key part of the inner ear responsible for hearing. The results could pave the way for developing new treatments for those with hearing impairments.

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.

New Research Throws Doubt on Old Ideas of How Hearing Works

A new study casts old theories about hearing into doubt. Researchers found many cells in the inner ear react simultaneously to low-frequency sounds. This makes it easier for us to hear low-frequency sounds as the brain is able to receive input from many sensory cells at the same time.

A New Mechanism Responsible for Controlling Auditory Sensitivity

Researchers identified a new mechanism by which auditory sensitivity is regulated. The mechanism can temporarily reduce sensitivity in the auditory system to protect itself from loud sounds that can cause hearing damage.

Origins of human language pathway in the brain at least 25 million years old

Studying auditory regions and brain pathways in humans, apes, and monkeys, researchers have identified a language pathway that interconnects the auditory cortex with frontal lobe regions. The language pathway in other primates suggests an evolutionary basis in auditory cognition and vocal communication.

Mild-to-moderate hearing loss in children leads to changes in how brain processes sound

The brain activity response to sound in older children with hearing loss was lower than their peers with normal hearing.

Reducing brain inflammation could treat tinnitus and other hearing loss-related disorders

Rodent study reveals noise-induced hearing loss is associated with elevated expression of proinflammatory cytokines and microglia activation in the primary auditory cortex. Pharmacologically depleting microglia helps prevent tinnitus in mice with noise-induced hearing loss.
