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.
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.
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.
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.
Auditory and speech processing occurs in parallel in the brain, researchers report. The findings contradict the belief that the brain processes auditory information before transferring it into linguistic information.
