The auditory cortex is the region of the brain that is responsible for processing of auditory (sound) information. The primary auditory cortex is located in the temporal lobe. There are additional areas of the human cerebral cortex that are involved in processing sound, in the frontal and parietal lobes.
Intact hearing is a prerequisite for learning to speak. This is why children who are born deaf are fitted with so-called cochlear implants as early as possible. Cochlear implants consist of a speech processor and a transmitter coil worn behind the ear, together with the actual implant, an encapsulated microprocessor placed under the skin to directly stimulate the auditory nerve via an electrode with up to 22 contacts.
It is a listening or hearing disorder, which is due to the brain’s defective analysis of sounds, so that individuals who are affected with this disorder cannot make sense of what they hear.
Twenty years ago Khaleel A. Razak was an electronics engineering student focused on creating a telephone for hearing-impaired children in Chennai, India. Today he is a neuroscientist at the University of California, Riverside whose research on how the brain processes everyday sounds may lead to therapies for age-related hearing problems and Fragile X Syndrome.
The cerebral cortex contains two major types of neurons: principal neurons that are excitatory and interneurons that are inhibitory, all interconnected within the same network.
Short-term hearing loss during childhood may lead to persistent hearing deficits, long after basic auditory sensitivity has returned to normal. The processing of sound in the brain is shaped by early experience.
By studying how memories are made, UC Irvine neurobiologists created new, specific memories by direct manipulation of the brain, which could prove key to understanding and potentially resolving learning and memory disorders.
During a normal conversation, your brain is constantly adjusting the volume to soften the sound of your own voice and boost the voices of others in the room.
Anyone who's ever heard a Beethoven sonata or a Beatles song knows how powerfully sound can affect our emotions. But it can work the other way as well - our emotions can actually affect how we hear and process sound.
The distribution of white matter brain abnormalities in some patients after mild traumatic brain injury (MTBI) closely resembles that found in early Alzheimer's dementia, according to a new study published online in the journal Radiology.
How can healthy people who hear voices help schizophrenics? Finding the answer for this is at the centre of research conducted at the University of Bergen. Researchers from the Bergen fMRI Group at the University of Bergen (UiB) are working on how to help schizophrenics, who hear voices. The way they do this is by studying people who also hear voices, but who do not suffer from a mental illness.
In a study published in the Journal of Neuroscience and funded by the Wellcome Trust, Newcastle University scientists reveal the interaction between the region of the brain that processes sound, the auditory cortex, and the amygdala, which is active in the processing of negative emotions when we hear unpleasant sounds.
UT Dallas researchers recently demonstrated how nerve stimulation paired with specific experiences, such as movements or sounds, can reorganize the brain. This technology could lead to new treatments for stroke, tinnitus, autism and other disorders.
The longstanding mystery of how selective hearing works - how people can tune in to a single speaker while tuning out their crowded, noisy environs - is solved this week in the journal Nature by two scientists from the University of California, San Francisco.
Scientists at the University of California at Berkeley have devised a method by which they can hear thoughts. They conducted a small study in which they could predict what people were thinking based on their brain activity.
The study, initiated by the Swiss researchers and published in Nature, constitutes ground-breaking work in exploring emotions in the brain.
The perceptual feature of sound known as pitch is fundamental to human hearing, allowing us to enjoy the melodies and harmonies of music and recognize the inflection of speech. Previous studies have suggested that a particular hotspot in the brain might be responsible for perceiving pitch. However, auditory neuroscientists are still hotly debating whether this "pitch center" actually exists.
A new wireless device to help victims of spinal cord injury is receiving attention in the research community. Mesut Sahin, PhD, associate professor, in the department of biomedical engineering at NJIT, recently has published and presented news of his findings to develop micro-electrical stimulators for individuals with spinal cord injuries.
Neuroscientists at the University of California, Berkeley, are offering hope to the 10 percent of the population who suffer from tinnitus - a constant, often high-pitched ringing or buzzing in the ears that can be annoying and even maddening, and has no cure.
During sleep, our perception of the environment decreases. However the extent to which the human brain responds to surrounding noises during sleep remains unclear. In a study published this week in Proceedings of the National Academy of Sciences (PNAS), researchers from University of Liège used brain imaging to study responses to sounds during sleep.
A new study by researchers from the Perelman School of Medicine at the University of Pennsylvania shows that declines in hearing ability may accelerate gray mater atrophy in auditory areas of the brain and increase the listening effort necessary for older adults to successfully comprehend speech.
