Auditory Cortex News and Research RSS Feed - Auditory Cortex News and Research

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.
Scientists reveal interaction between the auditory cortex and amygdala

Scientists reveal interaction between the auditory cortex and amygdala

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.

Study demonstrates how nerve stimulation paired with specific experiences can reorganize the brain

Study demonstrates how nerve stimulation paired with specific experiences can reorganize the brain

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. [More]

UCSF scientists solve mystery of how selective hearing works

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. [More]
A mind-reading machine could be reality soon

A mind-reading machine could be reality soon

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. [More]
Cortex plays a key role in fear learning

Cortex plays a key role in fear learning

The study, initiated by the Swiss researchers and published in Nature, constitutes ground-breaking work in exploring emotions in the brain. [More]

New review article: Pitch center does not exist in auditory cortex

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. [More]
Micro-electrical stimulators for spinal cord injuries

Micro-electrical stimulators for spinal cord injuries

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.

UC Berkeley scientists offer treatment hope for patients with tinnitus

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. [More]

Study: K-complexes control effects of noise on sleep

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. [More]

Age-related declines in hearing may accelerate brain atrophy

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. [More]

Conference to explore new discoveries about origins, diagnosis and treatment of tinnitus

University at Buffalo research showing that a new drug that eliminated tinnitus with a single dose in animal models is among the advances that will be presented at the Fifth Tinnitus Research Initiative Conference, "The Neuroscience of Tinnitus," sponsored by UB's Center for Hearing and Deafness Aug. 19-21 in Grand Island, N.Y.

American Tinnitus Association awards $10,000 to Wayne State University student

Na Zhu, a Wayne State University College of Engineering student, has received the 2011 American Tinnitus Association Student Research Grant Program award. The program financially supports scientific studies that investigate and aim to find a cure for tinnitus. [More]
GUMC neuroscientists: Speech perception must have evolved from animals

GUMC neuroscientists: Speech perception must have evolved from animals

Neuroscientists at Georgetown University Medical Center (GUMC) have defined, for the first time, three different processing stages that a human brain needs to identify sounds such as speech - and discovered that they are the same as ones identified in non-human primates. [More]
Wayne State team receives $330,000 NSF grant to develop 3-D neural probe for tinnitus

Wayne State team receives $330,000 NSF grant to develop 3-D neural probe for tinnitus

A team of Wayne State University researchers was awarded $330,000 from the National Science Foundation (NSF) to develop a 3-D neural probe. Their aim is to develop an implantable device that will suppress tinnitus, a neurological disorder that affects more than 250 million people worldwide. [More]

Functional MRI acquired during speech stimulation predicts children with autism

Functional magnetic resonance imaging may provide an early and objective indicator of autism, according to researchers at Columbia University in New York City, who used the technique to document language impairment in autistic children. [More]

Research provides insight into brain reorganization following sensory loss

The part of the brain that uses hearing to determine sound location is reorganized in deaf animals to locate visual targets, according to a new study by a team of researchers from Virginia Commonwealth University and the University of Western Ontario in Canada. [More]

Study: Visual cortex can dramatically change its function

When your brain encounters sensory stimuli, such as the scent of your morning coffee or the sound of a honking car, that input gets shuttled to the appropriate brain region for analysis. The coffee aroma goes to the olfactory cortex, while sounds are processed in the auditory cortex. [More]
Scientists probe functional connectivity among neurons in auditory cortex gives rise to map of acoustic space

Scientists probe functional connectivity among neurons in auditory cortex gives rise to map of acoustic space

Just as we visually map a room by spatially identifying the objects in it, we map our aural world based on the frequencies of sounds. The neurons within the brain's "hearing center"-the auditory cortex-are organized into modules that each respond to sounds within a specific frequency band. But how responses actually emanate from this complex network of neurons is still a mystery. [More]

Part of brain reorganizes to enhance visual abilities in deaf cats

Deaf or blind people often report enhanced abilities in their remaining senses, but up until now, no one has explained how and why that could be. Researchers at The University of Western Ontario, led by Stephen Lomber of The Centre for Brain and Mind have discovered there is a causal link between enhanced visual abilities and reorganization of the part of the brain that usually handles auditory input in congenitally deaf cats. The findings, published online in Nature Neuroscience, provide insight into the plasticity that may occur in the brains of deaf people. [More]
Mental exercises may help reverse age-related cognitive decline

Mental exercises may help reverse age-related cognitive decline

Specialized brain training targeted at the regions of a rat's brain that process sound reversed many aspects of normal, age-related cognitive decline and improved the health of the brain cells, according to a new study from researchers at University of California, San Francisco. [More]
