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.
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.
Researchers reveal how the auditory cortex reacts to "wrong" sounds and shed light on auditory memory recall.
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.
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.
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.
Researchers have identified a network between the auditory cortex and thalamus that appears to blunt pain when an animal is exposed to specific sounds or noises.
A new map of the human brain reveals cells, receptors, and gene activity change along the same boundaries.
Stimulating a part of the auditory cortex called the planum temporale improved speech perception, researchers report.
Study sheds light on how various types of pulsations in the brain change while a person sleeps.
Researchers have identified a population of neurons in the auditory cortex that responds to singing, but not any other type of music.
Repeatedly listening to personally meaningful music induced brain plasticity and improved cognitive function for patients with mild cognitive impairment and early-stage Alzheimer's disease.
