Study reports a pervasive neuromodulation system strongly influences sound processing in a key auditory region of the brain. Findings suggest acetylcholine may assist in the brain's ability to distinguish speech from other noise.
Neural networks involved in the same computation will repeatedly converge toward the same firing rates, even if they are perturbed by the natural noisiness of individual neurons or sensory environmental stimuli.
Two activities support the brain's ability to establish reliable connections in the presence of significant biological background noise.
Noise-induced hearing loss and hearing loss due to aging have different effects on sound processing in the brain. Researchers suggest each type of hearing loss should have its own specific treatment.
According to a new study, the presence of background noise may make it more difficult for young children to learn new words.
According to a new study, brief exposure to mild trauma or sudden sounds can permanently alter neural networks and form long lasting memories.
