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.
Memories are formed through long-term changes in synaptic efficacy, a process known as synaptic plasticity, and are stored in the brain in specific neuronal ensembles called engram cells, which are activated during corresponding events.
Early-life seizures prematurely switch on key synapses in the brain that may contribute to further neurodevelopmental delay in children with autism and other intellectual disabilities, suggests a new study from researchers at Penn Medicine published online in Cell Reports.
Although sight is a much different sense than sound, Georgetown University Medical Center neuroscientists have found that the human brain learns to make sense of these stimuli in the same way.
Preterm babies born early in the third trimester of pregnancy are likely to experience delays in the development of the auditory cortex, a brain region essential to hearing and understanding sound, a new study reveals.
According to a new prospective and observational study published today in The Journal of Pediatrics, very premature infants suffer from an altered cerebral blood flow (CBF) of key regions of the brain which may help to warn of complications in brain maturation, far sooner than conventional imaging could visually reveal.
A study presented today at the annual meeting of the Radiological Society of North America (RSNA) suggests that neurofeedback training has the potential to lessen the severity of tinnitus or even eliminate it.
Whether it is dancing or just tapping one foot to the beat, we all experience how auditory signals like music can induce movement. Now new research suggests that motor signals in the brain actually sharpen sound perception, and this effect is increased when we move in rhythm with the sound.
Salk Associate Professor Tatyana Sharpee has been awarded a grant of approximately $950,000 over 4 years by the National Science Foundation to study how the brain processes complex sounds. This grant is part of a multi-national project together with groups in France and Israel.
The origins of autism remain mysterious. What areas of the brain are involved, and when do the first signs appear? New findings published in Biological Psychiatry brings us closer to understanding the pathology of autism, and the point at which it begins to take shape in the human brain.
People who are hearing impaired have a difficult time following a conversation in a multi-speaker environment such as a noisy restaurant or a party. While current hearing aids can suppress background noise, they cannot help a user listen to a single conversation among many without knowing which speaker the user is attending to.
By training mice to perform a sound identification task in a virtual reality maze, researchers at Harvard Medical School and the Istituto Italiano di Tecnologia (IIT) have identified striking contrasts in how groups of neurons in different cortex regions of the brain function during decision making.
A month before they are born, fetuses carried by American mothers-to-be can distinguish between someone speaking to them in English and Japanese.
Researchers have identified a network of neurons that plays a vital role in learning vocalizations by aiding communication between motor and auditory regions of the brain.
Traditional clinical hearing tests often fail to diagnose patients with a common form of inner ear damage that might otherwise be detected by more challenging behavioral tests, according to the findings of a University at Buffalo-led study published in the journal Frontiers in Neuroscience.
Early dementia is typically associated with memory and thinking problems; but older adults should also be vigilant about hearing and communication problems, suggest recent findings in a joint Baycrest-University of Memphis study.
Humans can be trained to use echolocation to estimate the sizes of enclosed spaces. Ludwig-Maximilians-Universitaet in Munich researchers now show that the learning process involves close coordination between sensory and motor cortex.
Researchers have provided new insight into the brain mechanisms underlying a condition that causes reading and writing difficulties.
Neurodevelopmental disorders like autism very likely have their origin at the dawn of life, with the emergence of inappropriate connectivity between nerve cells in the brain.
When you're suddenly able to understand someone despite their thick accent, or finally make out the lyrics of a song, your brain appears to be re-tuning to recognize speech that was previously incomprehensible.
St. Jude Children's Research Hospital scientists have identified a small RNA (microRNA) that may be essential to restoring normal function in a brain circuit associated with the "voices" and other hallucinations of schizophrenia.
